Customer Ratings & Reviews

Always easy, efficient and fast. I've used Amsoil for 30 plus years. In everything from motorcycles to

I swear by this oil. Simply the best fully synthetic oil out there. I got 220000 miles on my Altima and still has great fuel mileage and power.

The Best Oil for your car makes it run better than any other oil I have ever used, you will feel the difference in you car's performance.

I use this in my 454 big block one tone and she works hard pulling a 14000 pound trailer fantastic love it

I use Amsoil 0W-20 in my daily drivers, a 2008 Scion XD and currently a 2012 Honda Civic coupe. My workhorses receive roughly 110 miles a day / 24 to 26,000 miles a year. The Scion had over 186,000 miles on it when it was involved in an accident and was "totaled" in 2015. The engine never missed a beat, its last duty was to move its smashed up self onto flatbed tow truck.

I have been using this oil for years and my cars and trucks, all run cooler on this than they did on reg.oil. All of them start up easier in the cold weather and here it gets down below 0.Best oil I have found in my 74yrs. of life..

Used in all my vehicles. Season after season the best. An easier to read side window would be nice

This is the best motor oil on the planet. I have used it in all my cars with excellent results.

Amsoil 5-20 oil is great. I normally run it a little over 5k miles in my truck, no more then 7k miles, and don't notice a large drop in performance from then and after the oil change.

Great stuff

Great product! 2.5 to 3 mpg improvement!

This oil I use in my trailblazer and impala

I use this in my 2012 Silverdo with the 5.3 V8 and it is great. I run it for a year and forget about it. Keeps the engine clean and cool.

Amazing oil, the best you can buy, noticed improvements in mpg

Great stuff!

I've been using this oil in my 2010 Taurus SHO since I purchased it in 2012. I've been on an annual oil change for most of that time, but recently changed to twice a year after I had the oil analyzed to see the impact the turbos had. While the oil was holding up, it was clear that a more frequent oil change was warranted. I've used this oil in my wife's car and the predecessor of the SHO. I also use this in my 1977 Corvette (albeit a different grade) -- so all my vehicles are protected.

Have been using amsoil since its start before being called amsoil. Had a ford explorer for 13yrs 278,000 miles. Still had factory compression specs when I sold her.
