Customer Ratings & Reviews

It is a great product, I'm getting excellent fuel mileage.

I switched to Amsoil from Mobile 1 four years ago and have never looked back. Amsoil no doubt has the best machine lubricants, period.

The only motor oil I use in my vehicles.

The oil does not have that acrid burnt smell when I change it at 5K miles like the other brands that I have used. Time will tell how well it protects the inner workings of the engine timing chains bearings etc.

Its just simply the best oil money can buy.

I've been running amsoil signature series for 100k miles. I don't want to run anything else. I'm a diehard amsoil guy. We'll worth the $$.

I started using 0W-20 Ams SS on my 2.5L 3 at 67,000 but have switched to this when I realized that the manual only recommended it for USA & a few of it's eco-fanatic territories. Other countries (like Mexico) said that you "must" use 5W-30 in the non-turbo engine. I just got a turbo -- and there are no dual standards for oil -- and this is what I use in it.

Very good product, i’m running it in my 2018 Shelby GT 350 R, that is Whipple SuperChtaged

I have lived in Wisconsin and now Kentucky and have 251,000 miles on my Ford explorer using this product!

Put this in a 2024 Frod Edge ST. Works great

I have been using for years on many vehicles. Worth every Penny

This is great you feel the difference in the perforance of the vehicle.

Amazing product can't wait to see how it performs compared to royal purple

Over 300,000 km and no problems at all with the engine!

I run this in a toyota prius C and a Nissan pathfinder. The pathfinder is direct injected and the oil you pull out of that motor looks aweful even at 5000 miles. People have complained for years about the 3.5 l gunking and sludging up as well, so I've been running this in her. I still do the 5000 mile intervals and it still looks aweful coming out but with less breakdown I'm hoping to avoid the sludge these engines seem to produce. So far I'm very pleased. In the Toyota it does great as well with its 6000 mile intervals.

Amsoil is the only product I truly trust. From their engine oil, their transmission fluid and gear oil. My 19 Silverado, my 19 Equinox and my beloved 2010 Camaro SS. Amsoil products flow through them all.

Turbos make great sense for us living at high altitudes. The AMSOIL Signature oils have the right detergent package to avoid LSPI and the shear strength to keep engines lasting a long time.

Amsoil is the best, best by far of any motor oil

A never fail oil/filter purchase. I run this truck hard in both work and play, Amsoil keeps everything under control.

This is the best engine oil I have ever used for my Dodge Challenger. Thanks!
