AMSOIL #1 Choice for High Performance Supra


Dear AMSOIL,

I chose AMSOIL for one reason. It is the best bar none. A friend of mine sent it out to a lab and had it analyzed and compared it to a few others.  AMSOIL topped all others I chose in the past. This was something that was important to me because good oil is like having good blood.  It is the life in your veins. Anytime someone wants to know what oil I use, I tell them AMSOIL is the #1 choice.  Whether it be for a normal application or high performance street or drag race use, this is the oil to use.

AMSOIL Gives Life to a Sweet Old Cadillac
Making a skeptic into a believer.

Dear AMSOIL,

I thought you might appreciate hearing my AMSOIL story.

When the opportunity arose last year to purchase my mother-in-law's 1987 Cadillac DeVille, I jumped at the chance. A true low mileage survivor, it was in near pristine condition. I was proudly showing it off to a mechanic friend when he said, "Uh-oh, you bought an HT-4100? Good luck buddy."

After much research I understood what he meant. The HT-4100 was rumored to be one of the most troublesome engines Cadillac ever built. The problems are numerous: an aluminum block with cast iron heads that expand and contract at different rates causing premature head and intake gasket failure, coolant loss into the oil, and finally main and rod bearing failure. They also have a heavily loaded distributor gear, weak timing gears, and sludging issues.

My first thought was, if ever an engine needed AMSOIL, it's this one. I first heard about AMSOIL at the old Brohman Dragway in the late 1970s from a fellow racer who swore by it. For the past 10 years, I've used various synthetic oils with favorable results, but never AMSOIL. Then I talked with Dave Mann, the AMSOIL Dealer in my home town, and told him my story. Having spent 19 years as a lubrication specialist with Ford, Dave knows his stuff. He made several recommendations, and shared with me his excellent e-book on motor oils.

I also asked around at the Cadillac owners group I belong to, and almost every one of them said, "Don't buy AMSOIL! It's too expensive and won't do you any good. You need this or that oil with this or that additive," and so on.

So who was I to believe?

Having spent over 25 years in advertising and marketing, I have a strong skepticism for extravagant claims made by manufacturers. Usually, when you hear impressive adjectives like "advanced" and "superior," someone just wants your money or your vote (or both). So I read the science; from AMSOIL and from several independent studies. I came to the conclusion that it really is an excellent product. It also intrigued me that one of the primary sales points made by AMSOIL is to convince you to buy LESS of their product. That kind of marketing is contrary to anything I've experienced, and elevates AMSOIL's credibility level exponentially.

I switched the Cadillac over to AMSOIL 5W-30 (ASL) last fall, then put in AMSOIL 10W-30 (ATM) this spring (even though it's not a turbo, I like the extra wear protection offered by this formula). Rather than letting the oil go a full year, I change it every six months, during which time it accumulates about 6,000 miles. My dad was an auto mechanic and taught the 3,000-mile oil change rule like it was the 11th commandment - that kind of conditioning is hard to overcome. With this frequency, I still spend less money than if I changed the oil on a three-month/3,000-mile schedule. I use the money I save to have drain samples tested by an independent lab each time.

The Deville now has 50,000 miles and runs like a fine Swiss watch. I have not had a single problem with the 'troublesome' HT-4100 engine. It runs roughly 10 degrees cooler than with regular oil, and my gas mileage has increased by 10%. It has become my mission to get 200,000 miles from this car. With AMSOIL, I might just make it.

As an addendum, I also recently switched my wife's 2003 Oldsmobile Silhouette minivan to AMSOIL. Since we've owned it, this car has had a lifter clatter for the first 10 seconds on cold starts. Literally, on the first start after putting in AMSOIL, the clatter was gone.

Thanks AMSOIL. By making a superb product that truly does what you say it will do, you've given new life to a sweet old Cadillac, and made a believer out of this devout skeptic.

This is my seventh car/truck that used AMSOIL products.

I purchased my first diesel on March 11, 2001. The Ford Excursion had 4,727 miles on April 21, 2001 when the following fluids were changed to AMSOIL.

  • Engine changed to HDD Series 3000 5W-30
  • Transmission and transfer case changed to ATF
  • Rear Differential changed to Series 2000 SAE 75W - 140
  • Front Differential changed to SAE 80W-90
  • BK-16 By-Pass oil filter added to truck

This SUV engine has a 100,000 mile warranty from Ford. The engine oil has been analyzed every 10,000 miles since it was new and now has more than 98,000 miles on one oil change using the BK 16 By-pass filter system, without any problems.

In the last year, I have traveled over 40,000 trouble free miles, thanks to AMSOIL, and have towed a 8 1/2 X 34 foot travel trailer 10,000 miles during this time period.

On February 2, 2004, the PSD completed its first 100,000 miles looking forward to second 100,000. The engine does not have any white, blue or black smoke and no engine or transmission repairs in the first 100,000 miles.

Angler Is "Hooked" On AMSOIL

Guide Service Owner and Tournament Angler

David A. Zgrabik of Cleveland, Ohio, owns a guide service and is also a tournament angler. His success depends on the reliability of his equipment. He says he has always used quality oils, but has never seen the performance and sheer benefits from other products like he has seen from the AMSOIL product lineup. After starting to run AMSOIL Series 2000 2-Cycle Racing Oil, I noticed considerably less smoke at start-up, improved idling and more power, David said. I even have an unexplainable 200 rpm increase! Davids tow vehicle is another important part of his business.

 I travel all over when I'm fishing and doing other promotional work, David said. After installing AMSOIL engine oil and an AMSOIL filter, I noticed a 10-15 degree temperature drop while the engine was operating. I was just amazed at how well it was working. There was also an increase in fuel mileage. There is no way I would do without my AMSOIL motor oil now!

Hi, my name is Don Berger, Chief of Police, for the Hondo Police Department. We have a total of 12 cars that are driven hard each day. I like to keep them in the best running shape Possible.

On February 13, 2002, AMSOIL Dealer Troy Klump stopped by my office for about twenty minutes to talk about AMSOIL Synthetic Lubricants and how they would benefit our patrol cars and our budget. We do not have our own maintenance shop so we have it done at a local service shop. Troy explained that the patrol cars would start easier, perform better, last longer, get better fuel economy, need fewer repairs and reduce emissions. He also explained that AMSOIL lubricants are built for extended drain intervals, and we can save money on lubricant and maintenance costs by running AMSOIL lubes in the engines, transmissions and rear ends.

We originally ran AMSOIL lubricants in three patrol cars and now, starting in the middle of November, all of the cars will be flushed and filled with AMSOIL products in every application. We have seen great results since we switched to AMSOIL products and we are going to continue using them. Troy asked me if I thought anyone could benefit with AMSOIL and I told him that the more AMSOIL lubricants a person uses and the longer they use them the more benefits they will see. AMSOIL Dealer Troy Klump has been very helpful checking up on the Department to see if we needed any products, and if we do I tell him what we need and he orders it for us quickly.

Thank You,
AMSOIL for your Products

'Roadkill,' 'Traveler' Claim Mileage First
ROADKILL RIDES ON - AMSOIL Dealer Timothy Werder poses astride his 1999 Polaris-made Victory V92C motorcycle outside of his home in Shawangunk, N.Y.

AMSOIL Dealer Tim Werder, "Roadkill" to his friends, has racked up a first on the first new U.S. manufactured full-size motorcycle in 60 years.

Werder, 42, Shawangunk, N.Y., has more than 100,000 "butt" miles on his Polaris-made 1999 Victory V92C motorcycle.

While it's the world's highest mileage for the cruisers since the first Victory V92C production model rolled off the assembly line on July 4, 1998, Werder is an old hand on a bike. He's been riding since he was 16, even traveling more than 10,000 miles by motorcycle on his honeymoon with his wife Christine.

The love of motorcycles has always been a theme in Werder's life. He's put more than 100,000 miles on other bikes through the years and faced more than his share of dangers along the way. Five accidents, one that caused him life-threatening injuries, have not deterred him, nor has a 190-mile-a-day round trip commute to his state government job in New York City.

His bike, known as "Traveler," is powered by a 1507 cc air/oil cooled V-twin engine and has a five-speed transmission. The Victory bikes are manufactured in Osceola, Wis., with final assembly in Spirit Lake, Iowa.

Werder rides "Traveler" year round, even in the cold of the Northeast winter.

He owns another Victory, number 219 from the first year of production, and has on order a 2003 Victory Vegas with a new 1507 cc Freedom engine. He expects an early spring delivery date.

He uses AMSOIL 20W-50 Synthetic Motorcycle Oil (AMV) in the summertime and in the winter switches to AMSOIL SAE 10W-40 Motorcycle Oil (AMF). He also has installed an AMSOIL SMF-103 Oil Filter.

"I recommend this combination to my Victory customers as well," Werder said. "I'm extremely pleased with the results I achieve from the AMSOIL products, and I've specifically had oil analyses performed to maintain awareness of fluid performance."

His earned the nickname "Roadkill" because "I've hit five deer, all while motorcycling, never in a car," Werder said. In one of those acddents, Werder nearly lost his leg. His wife and two sons share his love of motorcycles and work with him in his AMSOIL business.

He is former national vice president for the Victory Motorcycle Club and former corporate ride coordinator for the Victory Riders Association. He organized group rides for association members during the group's first year. Werder joined the Marine Corps in 1986 and went to basic training on Parris Island. There he may have logged another first — as oldest recruit.

Drill instructors repeatedly made him yell out his age. "Sir, I'm 26, Sir!" Werder recalled of his time there. He became a logistics/embarkation specialist staff sergeant with Aerial Refueling Squadron VMGR- 452, Newburgh, NY. That unit was reactivated on Feb. 8, 2003 and sent to the Middle East. They haven't seen active duty since the Persian Gulf War.

The veteran rider has logged nearly 500,000 miles on motorcycles. "My 26 years of riding has brought me to a butt-total of over 479,000 miles, including three 100,000 plus-mile motorcycles with a variety of trailer and sidecar-towing duties, and even though I live in the Northeast, I normally ride through the seasons, expecting my bikes to accept what I dish out. AMSOIL gives me the confidence to do so," Werder said. "I anticipate the 500,000-mile mark this summer, and always recommend AMSOIL to fellow riders, regardless of the make of bike they ride."

He caters to motorcycle riders in his AMSOIL business, especially Victory riders, he said, but he may expand that business when he retires from his full-time job. "I consider myself a voice for many motorcyclists, and am a long-time member of the American Motorcyclist Association, Motorcycle Rider's Foundation and ABATE," he said. He also maintains an online publication "The Victory Digest."

As Roadkill says, "Ride on."
New Jersey Car Passes Inspection With AMSOIL

Dear AMSOIL:

A friend of mine has debated for several years on using AMSOIL in his cars saying that it was too expensive. I have tried to tell him that in the long run it is cheaper.

About three weeks ago he came to me and said his car will not pass New Jersey State inspection because it smokes when accelerated and did not think using AMSOIL would get the car to pass inspection by eliminating the smoking. I told him that if his oil rings were in fair shape, AMSOIL would most likely stop the smoking when accelerating. The inspector told him he would have to have the motor over-hauled.

He purchased 4 quarts of AMSOIL 10W-30, Engine Flush and a filter.

He stopped last night (March 19, 2002) and told me that his car passed inspection with flying colors and the only thing he did was to use the AMSOIL Engine Flush and the 10W-30 Motor Oil.

He was planning on over-hauling the engine this summer, but since the car passed inspection he has decided to see how many more miles he can go before he must rebuild the engine. The car presently has 220,000 miles on it.

He has now decided to convert his other car and his pick-up truck to AMSOIL.

I have never see a person so excited and happy as he was when he stopped here. he had just come from the inspection station and couldn't wait to tell me that AMSOIL is more than he expected. he has noticed the easier starting on cold mornings; no more valve lifter clacking and oil pressure is there as soon as he starts the car.

We have another satisfied and happy customer.

Thank You,

Dear AMSOIL:

I wanted to tell you about an event that happened to my family and I when first using AMSOIL. It was back in 1992 and a friend introduced me to Ray DesMarais (now my direct jobber) in Rochester, MA, and it only took Ray a minute to turn me on to AMSOIL. I switched my brand new 1992 Subaru over at 5,000 miles and that winter my family and I were on a ski trip to Bretton Woods, NH located across from Mt. Washington. 

The temperature that Saturday morning was below zero while we sat in the breakfast room of Carlson's motor lodge and Mr. Carlson explained to us that the tow-truck was stuck -- he couldn't get his engine started. And so, we bundled up after breakfast, went outside where we found at least a foot of newly fallen snow on top of a foot that fell on Friday and a few of us shoveled out a path to our drivers side doors. There must have been at least 8 to 10 cars, trucks, vans, etc., in the lot. Everybody ended up with dead batteries except me. I got in, turned the key without pressing the accelerator, and the starter was whining, then turned it off, then tried again without pumping any gas and on the second try, it started. It was very quiet at the time and the people that were still out there came running over to see how I started my engine. I simply pointed to my AMSOIL stickers and said that is the only reason why my engine turned over. They were all in disbelief. I let the engine run while we packed up and off we drove to the ski area. 

Even though we only took a couple of runs that day, it was much too cold no matter how well you were dressed but, we were delighted to know that we could start the engine and forever are grateful to AMSOIL. It could have been a circumstance of far more importance and from that time on we have been driving with confidence knowing that AMSOIL is under the hood.

Again thank you.

Respectfully,
Douglas C. Oliveira, ZO#505194

AMSOIL Quality Beats Competitor, Earns New Customer

AMSOIL Preferred Customer Mark Tweedale, Neenah, Wis., learned about the quality and cost savings he can depend on with AMSOIL Series 2000 2-Cycle Synthetic Racing Oil after a hard lesson using Pennzoil-Quaker State oil in his watercrafts.

The watercrafts are stock Kawasaki Ultra 150s, bought new in 1999 and 2000. They have a triple cylinder 1200cc motor that puts out 145 horsepower with a top radar speed of 65 mph.

"They are Kawasaki's top of the line muscle crafts," Tweedale said.

The machines use a race spark plug that costs "a whopping $15 each," Tweedale said. "I began fouling plugs almost immediately into their use."

In fact, he fouled out 30 plugs in the first year. He took the watercrafts back to the dealer to try to identify the source of the problem. "The dealer found nothing mechanically wrong with my watercrafts," Tweedale said. The dealer told Tweedale none of his other Ultras had experienced this plug fouling problem.

Tweedale began to suspect his oil and he contacted Pennzoil-Quaker State about the problem, explained the expense of the plugs and that the machines were mechanically sound. "I asked them for help and possible reimbursement for my plugs," Tweedale said.

Pennzoil-Quaker State sent a letter requesting Tweedale send in some of his oil for analysis. After the oil had been analyzed, Tweedale received a letter from the oil company stating that, while the oil's additives showed signs of breakdown from aging, it was not to the extent that it would foul plugs in his watercraft. "They offered me no reimbursement toward my plug expense," Tweedale said. They did offer him a gallon of their synthetic oil.

While talking with coworkers, he discovered Gary Yashinsky, an AMSOIL Preferred Customer in Green Bay, Wis. Yashinsky "had only positive things to say about AMSOIL," Tweedale said. "He truly went the extra mile to help me solve my problem and also to promote AMSOIL."

Tweedale was convinced. He had the Series 2000 Racing Oil installed in the watercraft early in the spring of 2002.

"I went the entire summer with no fouled plugs in either watercraft," Tweedale said. "Unbelievable. What a difference oil can make."

He became a Preferred Customer and does everything he can to promote AMSOIL products to his friends and coworkers. "I will be an AMSOIL Preferred Customer forever," he said. "Thank you AMSOIL for putting out a quality product which in turn solved this problem for me."

He does most of his watercrafting in Lake Superior, the world's largest freshwater lake. Generally, Tweedale starts his trips on the big lake at Munising Bay. He plans this summer to complete a ride started last year with his friend Todd Olson of Gwinn, Mich., that traverses the shoreline along the entire Upper Peninsula. "We completed half of it last summer and simply ran out of nice weather," he said. "It's one cold lake and can get downright violent at times. That's what makes it a challenge."

This year, the trip takes them from Little Girls Point north of Ironwood, Mich., around the peninsula and back to Houghton; the final leg covering the distance from Grand Marais to Sault Ste. Marie.

When their journey is over this year, the two—along with Olson's wife, Gina Olson, and Tweedale's fiance, Kristi Krajewski, who will join them at different stages along the coast—will cover nearly 400 miles. That's in addition to a nearly 200-mile trip last year. They plan the trip in stages because the lake takes its toll on their bodies.

"We move on as soon as our bodies and muscles recover from the pounding of the first (stage)," he said. "We tend to get beat up a little bit out there on (Lake) Superior. North winds are bad."


409,000-Mile Oil Drain Interval Mack Engine Teardown

After 409,000 miles without an oil change, the AMSOIL-protected Mack E7-400 engine in this truck was as wear-free as an engine in comparable service treated to TWENTY TIMES the oil changes.

COLONIAL HEIGHTS, VIRGINIA I didnt see any surprises in there at all. Based on my experience with AMSOIL Motor Oil, it came out the way we expected, said owner/ operator Haywood Gray (right) of his 1990 Mack E7-400 engine. It came out in good shape, exactly what youd expect for a well-maintained engine with 630,000 miles. Yet the engines oil had not been changed for 409,000 miles!

Gray began using AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil (AME) in the E9-400 V-8 engine of his first truck, a 1984 Mack, after the engine accumulated 45,000 miles. For 280,000 miles, Gray changed his oil at 40,000-to 60,000-mile intervals though his oil analysis reports showed, without exception, that the oil was good for continued use. At 325,000 miles, Gray increased his oil drain interval to 100,000 miles. The engine was torn down at 600,000 miles when Gray decided to sell the truck. The cylinder liners, bearings, pistons, rings and oil pump, all treated to extended oil drain intervals with AMSOIL, were found to be in excellent condition. Gray continued using AMSOIL AME in the engine of his new truck, a 1990 Mack with a E7-400 engine. With the new truck, instead of using 100,000 mile drain intervals, Gray began basing his oil drains on the findings of a used oil analysis program. He also installed an AMSOIL By-Pass Oil Filter. After 630,000 miles total and 409,000 miles without an oil change, the E7-400 engine was torn down by the local Mack dealership in December 1996 and its parts were examined by an engine rater from a major oil additive manufacturer.

Findings
The engine showed light to moderate wear throughout, just as an engine in similar service and lubricated with conventional oil changed at 15,000- to 20,000-mile intervals would show. In fact, according to the engine rater the parts he examined cylinder liners, pistons, rings, bearings, valve train components could have been put right back in the engine and would have continued to provide the good, dependable service they had provided all along after 409,000 miles without an oil change!

Discussion
Many factors enable AMSOIL to be safely used 20 times longer than petroleum oils may be used:

Stability AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil is far less prone to thermal and oxidative breakdown than are petroleum oils. Stability inhibits the formation of carbon deposits, varnish, sludge and acids, which helps the engine run clean and protected.

Neutralization ability While rapid TBN loss often renders conventional oils unfit for continued use, 12 Total Base Number (TBN) AMSOIL Synthetic Heavy-Duty Diesel and Marine15W-40 Motor Oil offers lasting protection against engine corrosion.

Viscosity retention Some conventional oils viscosity slips out of specification within a few thousand miles of an oil change. AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil neither loses viscosity as shear-prone oils do, which promotes wear during high temperature operations, nor gains viscosity as oxidation-prone oils do, which promotes wear during startup and cold temperature operations.

 

The pins show no wear at all. The piston crowns and lands show a normal amount of carbon. The skirts are very clean with a few fine vertical lines.
Independent engine rater
The rings are very, very good. All the rings are free. None are broken. No plugging whatsoever in the oil rings.
Independent engine rater
Probably 95 percent of the crosshatching is still in the liners. No scuffing, no cavitation in the liners. The liners could go back in the condition theyre in.
Independent engine rater

Additional Demonstrations
Grays successful use of AMSOIL synthetic motor oil in extended drain service is not unique. AMSOIL has conducted demonstrations with fleets all over North America. In each instance AMSOIL has been proven safe and effective in extended drain use. In fact, these studies show that AMSOIL used in extended drain interval programs consistently delivers lower rates of engine wear than conventional oils used in conventional drain interval programs. 

The rater found the valve train components showed, very light wear. Very good. [I] find no wear on the shaft, which can be a heavily loaded area.

Southern over-the-road fleet AMSOIL was used in Cummins class 8 engines for 75,000-mile drain intervals; the fleets normal drain intervals were 15,000 miles.

Upper midwest grocery fleet AMSOIL was used in Cummins NTC 350 engines for 74,000-mile drain intervals; normal drain intervals were 12,000 miles.

Northern grocery fleet AMSOIL was used in Detroit Diesel Series 60 engines for 79,000-mile drain intervals; normal drain intervals were 20,000 miles.

Virginia Beach, Virginia owner/operator AMSOIL was used in Cummins 350 engine for 325,350 miles without a drain.

Midwestern trucking fleet AMSOIL was used in Detroit Diesel Series 60 engines for 60,000-mile drain intervals; normal drain intervals were 20,000 miles.

Northern tier over-the-road fleet In an ongoing demonstration, AMSOIL Series 3000 5W-30 is being used in a fleet of Cummins N-14 engines for extended drain service with oil drains based on the findings of used oil analysis. One change was performed at one year with 125,000 miles on the AMSOIL. The oil was recommended for continued use. Normal oil drains are done at 20,000 miles. 

Again, very, very light wear. These could be put right back in and used again. In an extended drain program [with petroleum oil] theres a possibility you could see maybe half again as much wear.

Independent engine rater

Light wear. They compare to [those in] an engine that had 15,000- to 20,000-mile [petroleum] oil and filter changes.

Independent engine rater

Minimal wear. These, too, compare to [those in] an engine that had 15,000- to 20,000-mile [petroleum] oil and filter changes.

Independent engine rater

Except for normal top polishing on the push tubes the rater found, no wear to speak of. These can go right back in the engine and be used again. The push tubes were put back into the engine and are in use today.

I see no reason why it [the engine] couldnt run on. Independent engine rater

WHAT MAKES AMSOIL SO GOOD?
Synthetic basestocks, top-quality additives, and most importantly, more experience formulating synthetic motor oils than any other oil company, says AMSOIL Director of Technical Sales Dave Anderson. 

AMSOIL first put a long-drain synthetic diesel oil on the market in 1975 and since then has introduced three other long-drain synthetic diesel oils.

DOES AMSOIL OFFER A WARRANTY?
Yes. AMSOIL warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL products are used in full compliance with AMSOIL recommendations.

AMSOIL extended drain interval recommendations are set at a minimum of two times or more than the engine manufacturers recommendations as determined by oil analysis. Diesel operators who use AMSOIL for extended drains are fully protected.

Studies have proven time and again that extended drain intervals with AMSOIL are a win/win situation truckers win with less downtime and oil expense and they win big with reduced engine wear.

AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil Aces Test!

Haywood Gray has his used oil tested regularly to ensure the ongoing serviceability of the oil and well-being of the engine. In the engine oil report card, wear metals tell the whole story. A high wear metal content indicates a high rate of engine wear. In fact, most engine manufacturers publish upper limits on wear metals content at which an oil must be changed to assure continued engine protection. Even after 409,000 miles, AMSOIL protected better than Mack limits required. Now thats protection! 

What Is Oil Analysis?
Oil analysis is a maintenance management tool that allows users to monitor equipment condition for maximum equipment life, maximum lubricant drain interval length and optimal downtime scheduling. Oil analysis saves users significant money by reducing equipment replacements and repairs, reducing the volume of lubricant purchased and destined for disposal and, most of all, by reducing downtime.

Oil analysis customers like Haywood Gray trendline their oil analyses. Trendlining involves comparing the results of previous oil analysis reports to those of the most recent report to establish trends in wear metals content, viscosity, acid content, acid neutralization ability and other characteristics as specified. Departures from established trends indicate a change in engine or lubricant condition and the information they provide may be used to correct abnormal conditions before they cause damage or failure.

AMSOIL Oil Analysis
The AMSOIL oil analysis program puts technologically advanced testing equipment in the hands of experienced diagnosticians to deliver accurate, reliable, useful results.

Still wondering if AMSOIL is the World's Finest Lubricant?
