A Sampling of Satisfied AMSOIL Customers:

A Major Michigan Municipality Fleet: This letter is a summary of a letter written by the Superintendent of Motor Pool. Please contact us if you would like the full letter mailed or faxed to you.

This Municipality has switched its entire Police and City Hall Fleet (approximately 350 vehicles) to AMSOIL Synthetic Lubricants.

History: In the past, all marked and unmarked police vehicles would come in monthly for an oil change, lube and safety check. As a test, we switched two marked Chevrolet Caprice vehicles over to 100% synthetic AMSOIL engine oil and extended the drain intervals to 20,000 miles, with a new oil filter installed at 10,000 miles. The vehicles were still scheduled to come in monthly for a safety inspection (tires, brakes, suspension, lights, etc...), but the oil is not drained, only a sample is taken. When the two test vehicles reached 70,000 miles, the municipality service technicians removed the oil pans and also removed the main and rod bearings to check for wear using the plastic gauge test. The bearings showed very little wear. the same procedure was performed on two marked cars, same year, make and model, using petroleum oil. The wear on the two vehicles with petroleum oil, changed monthly at about 2,500-3,000 miles, showed slightly more wear in the plastic gauge test. The results were well within specifications in both cases.

Currently the city is using all Ford Crown Victorias in its police fleet. With the help of oil analysis, we were able to extend our oil changes to 18,000-20,000 miles with a new filter installed at 9,000-10,000 miles. We are currently using AMSOIL synthetic engine, transmission, and rear differential oil in all vehicles serviced out of the city hall facility.

SAVINGS: Savings have been noticed due to the decrease in number of oil filters and quarts of oil purchased and disposed of. Labor time to complete a preventative maintenance (A or B) on a vehicle has been reduced, allowing up to 50% more vehicles to be serviced each day. To date, we have not had to re-build an engine or transmission with the new extended oil change intervals.

I am writing to let you know how pleased I am with the AMSOIL program that you helped set us up with. For the past 25 years our fleet of trucks, mostly Navistar/International 4600 Series trucks, have been using regular petroleum-base lubrication products. We thought that we were happy with our lubrication program until we were introduced to AMSOIL.

I was very reluctant to switch from regular lubricants to fully synthetic lubricants because the benefits of AMSOIL seemed too good to be true. To be honest, when I was told that the motor oil could go as long as 100,000+ miles without changing, I didn't believe it. I can tell you now I am a true believer.

We have been using AMSOIL now for about 4 years and have changed the entire fleet to AMSOIL synthetic lubricants. We use the By-Pass oil filtration system on all of our trucks with the Synthetic Heavy Duty Diesel and Marine 15W-40 oil. We use AMSOIL grease and use the 75W-90 gear lube for the manual transmissions and differentials and the synthetic ATF transmission fluid for the automatics.

What do I get out of using AMSOIL? A lot!! After becoming fully synthetic on all of my trucks, I picked up an average of 5% in fuel savings. I haven't had to change my oil since I switched...4 years ago! I can't tell you how much money that has saved me in time alone. I have several trucks with over 100,000 miles on the oil and I am still getting high marks when I send the oil in for analysis But the best benefit is the decreased wear and tear on my equipment such as the pistons, cylinder heads and walls, transmission gears and differential gears. That is the most important to me because it means I can leverage my fleet longer, which translates into saved dollars. It means I can put those extra dollars to work in another area of my business. My average truck life has gone from 7 years to more than 15 years! UNBELIEVABLE! I have estimated the savings from better leverage alone will save me over $20,000 per year.

Thanks for all the help as I've implemented this new program. I am absolutely ecstatic about the results so far and I look forward to a long and fruitful partnership with you and AMSOIL.

All light, medium and heavy duty trucks, chippers, loaders and other equipment has been converted to AMSOIL lubricants and filtration systems. Action Tree has some of the most specialized equipment in the business, including a custom designed 80 foot in reach aerial lift bucket truck which is a 2000 model year, 4900 Series International DT466 275 H.P. diesel with an Allison New World transmission. The company also has several large swaploader diesel trucks and Ford Powerstroke Diesel trucks.

All of Action Tree's vehicles and equipment use only AMSOIL synthetic lubricants and filtration systems. Every truck is equipped with AMSOIL 15W-40 Synthetic Heavy Duty Diesel Oil, Dual-Gard (for large diesels) or Dual-Remote (for Ford Powerstrokes) filtration system, AMSOIL gear lube and AMSOIL synthetic automatic transmission fluid. Each of the large diesel trucks has 77 grease fittings and lubrication points which are all lubricated with AMSOIL GHD Heavy Duty Moly Fortified Synthetic Grease. Since switching to GHD, Action tree has drastically reduced the frequency of required greasing due to the greases superior performance, while providing much improved lubrication and protection to critical components. All chippers and stump grinders use an autolube system with AMSOIL GLA and 00 Grade synthetic multi-purpose grease.

Eastwood Excavating of Traverse City, MI

Thank you for introducing us to the AMSOIL product line. Although this is our first construction season using AMSOIL products, we are experiencing a lot of good things. I will try to highlight some of the things that we've experienced to date. First of all, we had changed all of our fluids to AMSOIL in February 2000. We have yet to experience an oil change. To date all we've had to do is change the filters and draw a sample, send it in, get the results and experience more extended oil service life. Consequently, we've not had to dispose of any oil. Our services are so simple. We now perform them in the field instead of in the shop as we used to because all we need to do again is draw a sample, change the filter and top the fluid off. While the initial cost of the change over from our past oils to the AMSOIL system was expensive, it was certainly worth it because of the change over, we have a much better filter system providing us with much less equipment wear which provides longer equipment life with less overhauls and rebuilds.

Dave, you really made it easy for us starting with the first introduction to the AMSOIL product working with us, guiding us and actually working hands on with our mechanic to help us through some of the change-overs was a fabulous experience. The technical support that you provide us with helps us a lot and we really appreciate it when you just stop in to see how things are going making sure everything's okay and it's nice to know that your support is just a phone call away. This has been a very good experience. Thank you for your help.

Harley Davidson Owners Testimonials:

Dear Dave.....How's it going? Fine I hope. I just wanted to bring you up to date. I received my AMSOIL 20W-50 Motorcycle oil today via UPS. I wasted no time, and changed my H-D 20W-50 oil to your 100% synthetic. I can already tell a definite change in how my transmission shift's smoother! My engine sound's quieter, and I notice the throttle response is better, and more responsive. Although my H-D 2002 V-Rod only has 1976 mile's, and is still very new, I feel more confident for the future life of my fine machine knowing it now has adequate protection in the engine, transmission, and final drive. The wet clutch seems to be easier to operate as well. I showed my Harley pal's your wear test's specification's, and how poor a quality H-D 20W-50 really is, and some of them are now interested in switching their motorcycles to AMSOIL as well! One of my Harley pal's is a Master Diesel Mechanic, and he quit using H-D oil year's ago. He knows there are many better quality regular petroleum oil's out there than the way over-rated H-D brand! I will happily promote your product to other enthusiast's down the line. Thanks Again......Charles Graham
