"AMSOIL Testimonials of Satisfied Customers - Read From a Few Of Our Personal Customers and Acquaintances"

It never ceases to amaze me the number of friendly people we run into that have been using AMSOIL synthetic motor oil products. They all love to share their AMSOIL testimonials on the improvements they notice like improved gas mileage, cooler engines, cooler gear boxes, extended equipment life, and more. Let me share with you some of their stories:

Pontiac Montana Owner Saves Money at the Pump using AMSOIL Synthetic Motor Oil and High Flow Air Filter.

Hey Jesse,

Just wanted to drop you a line and let you know that before I changed my oil I checked the average miles per gallon on my wife's Pontiac Montana via the on board computer and she was getting 18.1 miles per gallon. I then changed her oil to AMSOIL synthetic motor oil and installed your air filter and just let her continue driving it. I checked it about 3 months later and her average miles per gallon had risen to 21.1. So she gained 3 miles per gallon switching to your synthetic motor oil.

AMSOIL Synthetic Motor Oil Provides Improved Gas Mileage Over Other Synthetic Oils.

Attn: Jesse Hull

This is to let you know that I changed the engine oil on my Chevrolet Astrovan using AMSOIL 10W-40 synthetic oil and also replaced my rear end gear oil with AMSOIL synthetic gear lube(75W-90) last summer. This is to prepare for a 3200 plus mile round from Lenexa, Kansas to Orange County, California. My Astrovan has a 4.3liter V6 engine with an automatic transmission. The summer temperatures during the trip varied from the 70s to the high 90s. Previously, my Astrovan was getting an average of 22 miles per gallon on another manufacturer's synthetic engine oil on the same round trip from Kansas to California. Using the oil you recommended, I averaged 24-25 miles per gallon. My driving conditions (vehicle speed and A/C usage)did not change, and with these results, I'm very satisfied and will stay with your Synthetic products for all my vehicles.

My 1993 Ford F350 with the IDI Banks turbo-charged truck has also just been converted to use AMSOIL synthetic engine oil and also running the AMSOIL engine oil bypass filter. I will let you know the differences on oil analysis between previous oil usage and your synthetic oil in the future.

AMSOIL Synthetic Motorcycle Oil Helps Harleys Run Quieter and Run Cooler.

"I had heard a lot of good things about AMSOIL motorcycle oil used in Harley Davidsons, so I decided to try it out in my 2001 Heritage Softail with the Evolution Series Twin Cam Engine. I noticed right away that the top end of the engine quieted down and on the hot days I run 12-15 degrees cooler than all the guys I’m riding with. I don’t sell your oil, but I recommend it after the improvement it made in my Bike."

AMSOIL Synthetic Gear Oils Cool the Most Severe Applications.

I own a grain dryer that requires a 90 degree gear box from the engine drive shaft to power the large fans via the drive belts. The tension from the drive belts created extreme conditions inside the gearbox. The gearbox used to get so hot you couldn’t touch it and you could smell oil burning. The seals would burn out and sling oil on the belts causing slippage that would require us to shut down and rebuild the gearbox.

After numerous bearings and even on entirely new gear box I tried your synthetic gear oil over the recommended gear oil and it solved my problem entirely. I don’t sell your product so this is not to benefit my pocketbook. It is just a true story of what happened with me.

AMSOIL Synthetic Oil Provides Superior Protection and Performance For Over 30 Years.

For two summers during my high school years I operated a hay bale hauling crew. The second year (the summer of '76) I had a 21' goose neck flat bed trailer that I pulled with a GMC trailer house tractor (short wheel base 2 ton truck). My dad and I built a wooden tool box / bed combination for the truck. It had a large hole in the center for the gooseneck hitch. We carried the drinking water jug for the crew in the toolbox. During breaks we would gather around the water jug for a refreshing drink. One of my crew was adamant about rinsing the dirt and hay dust out of his cup. He would toss this rinse water down that hole where it would land on the differential. By mid afternoon this water would sizzle.

Before the summer was over I had replaced the differential oil with AMSOIL synthetic oil. By this time the rinse water routine had became quite a game. Imagine the surprise of the crew the first time they tried the water game after the new oil was in the differential. The operating temperature had lowered enough the water simply ran off.

AMSOIL Synthetic Motor Oil Provides Superior Protection and Gas Mileage for a Ford Expedition.


Just wanted to get back to you regarding the AMSOIL 0W30 I am running in my Expedition. Truck seems to like the oil. I have noticed a slight improvement in fuel economy and the engine seems to be quieter at start up. I like the protection that the engine is getting, especially when I tow my trailer. I take care of my equipment and count on it to perform. I would like to see what you recommend for a 1978 JD 950 Tractor. It has a diesel engine (JD recomends 30W) which can get hot when cutting brush (radiator get clogged with seeds, debris, etc). I would also like to see about changing over the hydraulic fluid and the gear lube in my brush hog gearbox. The only thing left is my JD push mower. If you get a chance, lets discuss. Thanks again. Regards,

AMSOIL Synthetic Motor Oil Saves Me Time and Money.


About 4 months ago, I installed AMSOIL synthetic motor oil in my 2003 Expedition. Prior to thattime, my overall miles per gallon always indicated an average of 14.7 for a3-4 month period. Now, after 4 months of your synthetic motor oil, it indicates 15.0. Thatdoes not seem like much. However, I normally drive 35,000 miles per year. At$2.20 per gallon, I am saving $105 annually on gasoline plus I will need 2-3fewer oil changes. This will more than pay for the better oil and saves me time.

AMSOIL Synthetic Motor Oils Make Trucks Stronger and Smoother

Reinier drives a 2004 Dodge Ram. He uses Premium Synthetic 5W-30 in the engine, Synthetic Universal Automatic Transmission Fluid in the transmission and 80W-140 Long Life Gear Lube.

“Synthetic oil has given this truck life that it was hiding before,” said Reinier. Reinier said the Ram now pulls stronger and runs smoother than it did before. He made the switch to synthetic motor oil when the truck hit the 3,000-mile mark. “What comes as a surprise to me is that my Dodge dealer had no problem doing a complete drain and fill with the synthetic oil I brought,” said Reinier.

Reinier said the dealer removed all the Dodge transmission fluid and refilled the truck with our Synthetic ATF. “Within a mile or two I could feel the transmission was smoother and showed a difference in how it performed,” said Reinier.

Less Maintenance, More Performance with AMSOIL Synthetic Oils

Pickul drives a 1992 Geo Prizm with unusually high miles. As of February 2005 the Prizm had over 362,000 miles on only 15 oil changes and 31 filter changes. Pickul credits synthetic motor oil with extending the life of his car’s engine.

Pickul bought the Prizm new in June of 1992 and after 3,000 miles, converted it to 10W-30 Synthetic Motor Oil. Pickul also installed an 2-Stage Air Filter.

“In November 2003 with 329,000 miles on the engine, I drove the car from Sarasota, Fla., to Carbondale, Ill., without stopping,” said Pickul. “The 13-hour trip was a true tribute to the synthetic oilization of this vehicle.”

The Prizm has a 1.6 liter 4 cylinder engine that has had no major problems. The valve cover was removed at 360,000 miles and it was exceptionally clean.
