Customer Ratings & Reviews

Have this in my 2007 silverado.Seems to be doing as advertised.No engine problems at all.Runs great......Will continue using this oil.No cold starting issues with it.

Changed the oil on our 2014 Lincoln MKX.

My order arrived on time and un-damaged. I use Amsoil in my Gatortail engine (Briggs) replacing the oil at 25-35 hours with a total of 550 hours on the engine. The oil holds up very well. When conducting maintenance on the engine the interior working parts of the engine are like new with absolutely no visible signs of sludge build up. I highly recommend the use of Amsoil products. I also use the Amsoil Marine Grease in the lower unit and that product holds up very well as well.

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.
