I can say if I would of know Amsoil as growing up it’s great and can’t say bad about it

Great oil. Instant oil pressure on star up in cold weather.

So far awesome product

The top 2 best, most honest mechanics I know recommend Amsoil. I've been using it for a couple years now and agree it's the best. Most noticeable to me is starting my diesel in the winter has improved as I don't have to plug it in anymore and it warms up faster. Also like not having to change the oil as often. Worth the money.

This is very good oil for my 6.7 diesel. This is the best oil I have used in any of my diesel trucks.

I didn't realize there was such a size until I browsed the Amsoil site. I run the PPE filter on my Duramax so a big jug and small jug does the job with no leftovers. So convenient to get order sent to my home.

Love this oil, I have been using it for years

Runs smooth no oil burn

Quick delivery for a superior product, use Amsoil in all my vehicles

I did find that this lubricant worked on reverse in saying it will increase fuel mileage, my with backwards. I still continue using this oil for my 2015 GMC 3500 HD Diesel engine

best oil fastest service

best oil and fastest service

Tried many oils when I got my Duramax and this is the only stuff that takes the ticking away

There’s a lot of BS that gets passed around about what motor oil is the best. That being said, I run Zrod oil in any car I work on with flat tapper lifters. Several times I’ve had friends buy themselves a new toy/project car and the first thing we do is change all the fluids. Running Zrod after mystery oil actually makes the engines quieter! I’ve had several engines with lifter ticks become silent with just an oil change.

This oil takes all the worry if your is doing it’s job. Just use this and there is none better

I live out of my RV and refuse to take any chances. Great oil
