Just a change of oil and my truck idles better and just runs smooth going down the street. After many years of using whatever oil, making the switch has changed my mind. Wife’s truck next.

Trusted by the trucking industry for as long as I can remember. Amsoil is the best oil for any diesel vehicle application.

At the first start up after changing my oil to Amsoil, I immediately noticed how quiet my diesel motor is now. After driving on my first trip, I noticed the motor is running smoother than it did before, and I gained one mile per gallon. I plan on doing an oil analysis in the spring when I do another oil change. I will change both front and rear differentials next to Amsoil, and hope to see even more fuel savings. It was so convenient to order through Eben and my order was delivered to my front door within 2 days.

2022 Ram 2500 6.7L SO On my 3rd oil change. Works great! Would highly recommend

Excellent product and service

Put it in my 07 f250sd with a 6.0 What a difference, and got rid of that annoying knock that it has always had since new

Very high quality synthetic oil. Fast delivery. The AMSOIL team is perfect.

Best oil on the market hands down

I've used this oil for a while. Truck runs good on it.

This is the best oil you can buy and you get what you pay for. I put amsoil in everything I own because they care and I care to put high quality in my vehicles

My mechanic says this oil is as good (or better) than Rotella.

Provides faster cranking in cold weather and therefore easier extreme cold weather starts.

Best oil ever used

I have been using this oil now for about a year. It seems to be doing better as far as oil pressure goes compared to my previous oil. I have become a loyal Amsoil fan and user now!

Engine runs great after switching from Schaeffers and I received the product next day without pay for extra shipping.

Great oil, runs much cooler than the Ford synthetic I had to use in warranty. Even after 10K miles in Texas heat towing, oil keeps cool and the turbo is happy. Even after 10K miles the oil comes out slick. I use it in every engine and gear box in my truck, car and both motorcycles. Couldn't be more happy with an oil and additives.

Awesome product

18,000+ miles on first change using this product. Oil analysis was not perfect, but said to keep running. Since low miles on engine, decided to change.

I will only use this moving forward

Amsoil awesome product
