Use this in my 26 year old F350. Still runs like new. It's my farm truck.

great oil for my old big block ford highly recommend

Fast shipping and fantastic customer service. Will definitely be buying again

got a new car they said 20-50 I said Amsoil

I’ve almost always used BMW recommended products for my car. As I know my motor is higher compression and extended service intervals, I’ve chosen 20W50 Amsoil. This product is awesome and has met and exceeded my high standards.

Indisputably the best for our 1982 VW Westfailia Vanagon camp mobile!!

Been using Amsoil products for over 25 years. Would never use any other oil.

Would not hesitate to purchase any Amsoil product. I have a 1994 F350 with 200K plus miles and running strong thanks to Amsoil products.

Used in a motorhome with 1600kms so still a few MKS to go, but so far , very happy with the oil

Use in air cooled Porsche. Excellent oil with zinc additives for older engines.

This is the oil I use in my lawnmowers , The oil looks brand new every time I change it . They start and run like they are brand new !

I use this in the new 383 stroker engine in my 71 Nova, does a great job!

The best oil I have ever used for my 2003 Jeep WJ 4.0.

Amsoil AMO high zinc full synthetic is the recommended oil for my cars engine . The 90-95 Corvette ZR1 needs an oil with the correct additive package of zinc and phosphorus. It's LT5 engine with 4 cams, flat tappets , and 32 valves needs an oil that meets the manufacturers requirements. That oil use to be Mobil 1 full synthetic. Mobile 1 has reduced the zinc and phosphorus package in their current oil. Most new engines have roller valve train and they also reduced the package over catalytic converter life concerns. My engine builder recommends the Amsoil AMO product. It meets the original manufacturer recommendation . I use only Amsoil in all my cars . Especially my Corvette ZR1 with its exotic 528 horse power LT5 . It's cheap insurance .

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.

I works good
