Customer Ratings & Reviews

Upon installing this oil I immediately noticed lowered operating temps and quieter operation of my Jeep engine. very pleased overall with this oil I must say!

Use in all my Honda automobiles. Top notch oil.

I’ve been a fan for years! From the cold of Yellowknife NT (-40C) to the Rogers Pass BC towing the camper mid summer I never once was concerned!

Have been using Driven 10W40 for years, tried the AMSOIL 10W40 and have had great results so far.At a cost savings of about 6.00 dollars a QT. Thanks for Great Product!!

This is a great product for 10,000 mile oil change frequency. I have been using this product in all my vehicles.

This is good oil I use it in my mini

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.
