Customer Ratings & Reviews

We bought a used Volvo V70 with over 100k miles. The check engine light was on. the cause appeared to be the variable valve timing system. A very reputable shop pulled it all apart and reset everything to factory specs. they didn't find that the cam timing was wrong. The variable valve timing is actuated using oil pressure through small passages way up in the top of the engine. you could see that the engine had build-up by looking at the oil filler. 100,000k of cheap oil had left deposits and gunk. Now we are on our fourth change using Amsoil and the light is intermittent and even the oil fill area looks cleaner. Years ago Mobil One cured noisy lifters on my 1971 Cutlass. synthetic oil solves problems.

I have over 264,000 miles on my truck and I wouldn’t run anything in it but AMSOIL.

I started using XL 5w30 in my 2001 Silverado a few years ago and only had 89k miles on the clock. I now have 215k miles. No leaks, engine still sounds like a sewing machine.

great product recommended

All Amsoil products are hands-down the best lubricants and filtrations for the application you are thinking about. Try it - you'll become a lifetime user of the products. I have 4 personal vehicles that have achieved over 200K miles each and still running strong using these products for the last 19 years.

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!
