Been using this oil in my Chevy Silverado and have noticed an increase in mpg and money savings due to the extended life of the product and not needing to change oil as often.

Have been using Amsoil for the past two diesel trucks i've had the one i have now i had a head gasket problem. When I pulled the motor apart the cylinders still had the factory crosshatches and that is with 125,000 miles on it !!!!!!!!!! So I will be using nothing else in my vehicles and have turned alot of my friends on to Amsoil. Thanks for making such a great product !!!!

I have used Amsoil oil in my vehicles for over 20yrs and have had tremendous luck with it. No engine problems at all. I am now using the diesel oil and am having the same results. I constantly recommend Amsoil to people I know and talk to.

Still the same would not use anything else in my Diesel engine

was using rotella an truck was smoking Switched to amsoil and it quit

Started using amsoil truck runs so much better and doesn’t burn the oil like rotella

Always a great product. I wish it were available in those bags. That is a far superior container than these jugs.

Been running this in my 2004.5 ram 2500 Cummins for several years now. Tried other oils and it runs hot with AMSOIL in runs 20 to 30 degrees cooler. Great product

Amsoil is the only oil I put in all my Diesel engines. I love the next day delivery I will be a lifelong customer

No oil beside AMSOIL Heavy Duty makes my truck run the way it does.

I use amsoil in both diesel trucks and in my diesel welding machine

This "magic" oil reduce by half the engine oil consumption of my truck!!

Great product been using it for years

I’ve been using this stuff for a few years now on my Cummins and I strongly believe this is the best oil on the market.

I use Amsoil in my cars and motorcycles and just tried in my semi truck. Can’t believe the difference over other major brands. I was disappointed major brands because I do long oil intervals changed with my ops filter and oil test every 25000 miles. The major brands I couldn’t keep the base up to where it needed to be. I will update on my lab test on Amsoil after 25k . Plus my fuel mileage went up one tenth. We will see if this continues

Will use anything else

Switched over from Royal Purple and could not be happier.

All usual Amsoil doesn't disappoint. Great oil for Ram 6.7, and there deliveries rapid. Will always buy my oils from Amsoil

Worth the money

Quality stuff here. Long lasting good quality oil. A bit pricey but you get what you pay for
