Running oil in 2 dirt track cars, holds up good under pressure and high rpm’s

I have been using this oil since installing new longblock 25,000 miles ago. I trust my motor to Amsoil.

Hands down best oil. Perfect for my application. I put upwards of 3000 miles a week and I know I don't have to worry about my cam washing out

Have run Amsoil products in all my engines with not one oil related problem in over 30 years.

So far it seems to be working good I’m thinking my old motor has over 300,000 miles on it and it seems to be running more quite then before and good oil pressure. 👍🏻👍🏻

I works good

First time using the product so far so good.

I always try to use Amsoil in my E36 BMW M3. 20w-50 is hard to find and Amsoil has been tested to be the best around.

Great oil. I own a landscape company and We have been using it in all our equipment for years. It has stood up to all the abuses and helped our equipment last longer.

Gives me peace of mind about lubrication of my motor.

I've been using AMSOIL since 2002 starting with my Turbo Hayabusa all the way to current Big Turbo Subaru, this applies to engine, transmission or rear differential. Every time I refresh/rebuild my engine it always looks perfect and shows extremely low to no engine wear on the internals. Pay for the best and get the best!

Amsoil is the only oils I use in our 1982 VW Westfall Vanagon L Campervan

This is an excellent lubricant for motorcycles, as well as autos (JASO MA comp.)

Awesome oil at a great price and very fast shipping!!

A LITTLE PRICEY ,,, BUT IT IS THE BEST ,,,,

2000 miles of hard towing in oil still holding the same pressure and looks as clean as new. Has performed equally well from 80F down to 20F.

Since acquiring my BMW 328iC in 2012, I have been using Amsoil premium products. The car has 167,000 miles on it and looks and runs like new. I also use Amsoil in my work van. Great stuff.

I made the switch to 10w40 Amsoil after installing new longblock. Had been running 5w40 in the last motor. My tuner reccomended this oil after break-in was complete. I trust my EJ255 with Amsoil.

Began using Amsoil synthetic in my Dodge Ram equipped with a Cummings diesel engine and the engine performed without any issues when I sold the Ram in 2009. There were no leaks from the engine and it always started before making a complete revolution of the engine. I continue to use Amsoil synthetic oil in all of my vehicles and am very pleased with their performance.
