Best oil I have ever used. My twin turbo engine runs smoother than with the other the brand I was using. Also, I had a great experience with their customer service. Great product and service. Customer for life.
I run this oil in my C5 corvette. This car is used for HPDE and autocross. I only have 1 season with this car but I have a decade of experience with Amsoil. I don't want to keep a spare engine on hand, so this is the stuff I want in my race car!
Bottom Line
Yes, I would recommend this to a friend.

Great product, keeps my car running like new ,wouldn't change for anything else.
Amsoil is by far superior to any other oil I have ever used. The motorcycle oil is fabulous.My harley runs at least 20 degrees cooler in summer.I use Amsoil in every application where a superior lubricant is needed. You only get what you pay for.You get the very best with Amsoil products.My salesman Greg is the best!
Bottom Line
Yes, I would recommend this to a friend.

I’ve used the signature series oil for years. 200,000 on my last truck never had any problems. 175,000 on my current truck and still going strong. I travel and pull a camper we’re I go with a 1/2 ton truck. I love the fact that I can go 20,000 miles without changing oil. So that’s a money savings deal you can’t beat with the cost of oil changes ever 5,000 with conventional oil.
I use amsoil in everything I own it been rated the best on the market I got to make everything I own last as long as possible oil won't be the reason it wears out
