Matt from Santa Barbara, Ca switched his 2002 Jeep Grand Cherokee over to Amsoil synthetics at 104,000 miles. He used ASL 5W-30 in the engine, ATF in the transmission, Severe Gear fluids in his differentials and ATH in his transfer case. Here's what he had to say...

Jeep has felt great since switching to all Amsoil synthetics. Was close to trading it in on something new, but the new fluids have made a world of difference. Immediate MPG increase, improved shifting, and a general smooth feel throughout the drive train.

I can confirm a 3mpg improvement on the freeway. Just tested this out over 700 miles.

Thanks Gabe!


Brian from Westminster, Ca recently put Amsoil's MTF Syncromesh in the NV3550 5 speed transmission in his 2003Jeep TJ Wrangler. Here are his thoughts....
I replaced my transmission fluid with your product (5w-30 Syncromesh) and it made a huge difference when shifting. It fixed the notchy feeling I used to get when upshifting into 2nd.

Thanks again for a great product!
Last Friday, on the way home from work, my 2001 Ford F250 SuperDuty (7.3L Turbo Diesel) experienced an oil-out. Driving along at 55 mph, the first sign of trouble was the check engine light came on and the engine went dead. I coasted approximately .5 mile into a parking lot and got off the Highway. Got out, smelled oil, checked under the hood. Top of the engine was oil soaked and oil was running down the back of the engine onto the ground. I pulled the dipstick and it was dry! Now, being a bit of a gear head I am always checking gauges. The engine was not overheating at all. We changed the filter, drained what was left of the oil from the oil pan (only about 2- 3 qts left) and filled up with oil. Started the engine and drove to the dealership. The problem? A seal or o-ring had blown on the hi-pressure oil line to the oil pump that provides pressure to fire the injectors. $600 later I have a new oil pump, seal kit and hi-pressure oil line. Thanks to AMSOIL AME 15W-40 100% Synthetic Lubrication, I did not spend $10K for a new engine. Loosing 13 qts (16 qt total capacity) would normally spell engine failure. I've been an AMSOIL customer for several years and have had the everyday experiences of cooler running engines, increased fuel economy and the like. This experience further convinces me that AMSOIL is the way to go. We also use AMSOIL in our pulling garden tractors which helps make more horsepower and protects those air cooled engines. Thank you AMSOIL! -Randy K.
