Customer Ratings & Reviews

We have a 2016 Toyota Highlander with the V-6 engine. We bought it new from our local dealer. The did all the Toyota spec maintenance up to 30k miles, including oil changes. I then took over service and switched to the amsoil 0W20 XL oil with Toyota filters. Our highway fuel mileage had been consitantly 24-25 mpg. On that first oil change, it went to 27-28. I thought, road conditions, wind, etc. We now have 45K and driving between 55-65 mph we still get 27-28. Not sure what oil the Toyota dealer was using (supposed to be Toyota synthetic), and if the engine were breaking-in, it would be slowly. We noticed the change on that first oil change! And 15k miles is enough to get a good average mpg. Thank you, Amsoil!!

Just switched so time will tell 12000 on 04 super duty. I have always used Valvoline Synthetic for past 30000

Best protection and wont break the bank. Great protection. 4 vehicles with various mileages... everything from 80k to 315k and in between. Best on the market...hands down!

all good, very happy with product

I put nothing but Amsoil in my son's half-ton 2001 Chevy Silverado. The vehicle has over 350,000 miles on the odometer, and is going strong! I attribute that long engine life, at least in part, to the use of Amsoil products exclusively. --Mike

Very satisfied with the performance of this oil.

been using for over 20 years

Been a Driven user for years, Gave your oil a try was very impressed with the results.Price is very good compared to most oils of this quality.

I have used AMS Oil products for 35 yrs. I have always been happy with your products. The have never let me down. They have always shipped me my order in a very timely manner.

Best oil in the market. Can’t go wrong with Amsoil. A lot of people cheap out on oil and don’t get the results needed to maintain a healthy engine. Amsoil has never failed to provide the adequate properties to have a fully functional oil that provides best results. Way better than putting dealership “recommended” oil. Trust me, try it and you’ll get the best out of it and the mileage range of the oil is no joke.

I have been using Amsoil oils and filters for 30 years and have never encountered a problem that was caused by Amsoil products.

Just started using this in my wife’s 2019 Kia Sportage with an OE filter... So far, so good... Been using Amsoil for many years, never an issue...

I've used Amsoil XL series synthetic motor oil in our 2015 Chevy Equinox since purchased new. Oil and filter are changed each 5000-7000 miles, based on its internal oil change recommendation. Now, with over 130,000 miles, the engine uses no oil and shows no sign of sludge or discoloration under the filler cap. The Equinox 2.4L motor is known for oil consumption over time; ours behaves like new!
