Customer Ratings & Reviews

The oil is clean and my engine is running cooler and quieter since I switched from Mobil one oil.

Ordered this kit for my 2020 Chevrolet Silverado 5.3. AMSOIL. is one of the best holes ever used, and that is all I ever use in all my equipment.

I been using it for about 3years and can only say, I wish i knew about it sooner!

Best oil ever

197,000 miles on my For Explorer and still running great.

Great oil that slowed the consumption between changes.

It’s true AMSOIL is outdated, but in a good way. Nowadays companies pitch a whole lot of fluff stating their products are the best and list a bunch of “scientific terminology” to persuade customers to buy into their cheaply made products. This is where AMSOIL is outdated because they take pride and truly stand behind their products like companies use to do in the good ole days, while still advancing their lubricants (oil, transmission fluid, coolant, brake fluid, etc.). They’re underrated because when it comes to the government setting the bar on classification labels AMSOIL says that’s not good enough and sets the bar even higher. Long story short, AMSOIL is the bar and no other mega company comes close.

Since using Amsoil in my truck .. engine performance is smoother..cooler and oil lasts longer between changes

More power, better gas mileage, smoother running engine it sounds like and feels like it doesn't have to work so hard to get the same power as before. I'm homeless so I idle my car a lot summer/winter since I idle much more than a taxi cab or police officer remember I live out of my car year round I might go with 5w40 next time instead of factory recommended 5w30 this oil ain't no joke!!! 2005 Toyota Solara V6 SLE

Great products, fast shipping Amsoil is the best period!

I did the first oil change in my buddies new Lexus at 500 miles for the break in service. I will update this review at 3,500 miles at the next oil change service.

I only use AMSOIL products in my vehicles. I have done a lot of research and believe it’s the best product for my use.

Top of the line oil protecting my work truck

Run great

Love this oil - I use this in my 21 Jeep Compass

Best Oil you can buy period end of story. Amsoil is a great American company.

This is the best oil in the world. It holds up to all kinds of punishment and helps your engine to never develop leaks.

Manufacturer calls for 0W-20. 5W-30 just feels better for my hot climate. My 6.2 purrs as quiet as a mouse (If you ignore the growl of the Flowmasters)

I continue to use AMSOIL products, because they are excellent. Also, they ship their items extremely fast. The quality of the products far outweigh the cost.

Well, oil is oil, so there is not much to say about the oil. Now the bottle is worth talking about. The wide mouth on it meant I didn't spill any oil while pouring it into the engine. My order arrived very quickly, which is a plus these days. I have been having issues with parts arriving promptly.
