Customer Ratings & Reviews

I've converted my family to use AMSOIL in their vehicles as well. Order ahead and have it delivered to the house. Wish you included a sticker, to keep up with my due date/ mileage

Excellent product. Easy to purchase online.

Been running in my vehicles for about a year now and through out hard towing and engine abuse it has held up in molecular structure and viscosity. Definitely one of the best oils I have run in my vehicles.

I only use Amsoil synthetics in all my vehicles. I always get 200k plus mileage out of my trucks. Amsoil is the fastest shippers of any company, usually by next day or two it’s at my door. Will always use Amsoil on my vehicles, trucks, motorcycles and toys. Great product and company.

I use 10W30 in my Honda CR-V because I firmly believe that thicker oils are better for the engine. Although I haven't conducted any lab tests or in-depth research, I generally like this oil. I changed the oil at 3,700 km, which is about 200 hours of driving. The oil appeared dark, indicating that it contains effective detergents. I hope it performs as well as I expect and that its price reflects its quality.

Amsoil lubricates my high performance motor. I believe it does an excellent job preserving my engine and moving internal parts. Thank you for a wonderful product. 392 LV

This oil is the best on the market !

It’s fantastic to get a top-tier product at such a great discount. I signed up for my annual membership before making my first purchase and am excited to do more business with Amsoil in the future. Thank you for all your help!

Car runs smoother and oil stays cleaner longer with Amsoil. I used the best from the red horse brand and the one with the funny color. Amsoil is the absolute best in the many years of oil changes.

I've used Amsoil since the seventies when it was introduced to me by a colleague at work. He was running a race-prepped 427 Ford Fairlane. I've used it in all sorts of vehicles from a Land Cruiser to a Ferrari and have never had any lubrication issues. I just finished swapping a modified crate LS3 into a stepside and used Amsoil everywhere in the drivetrain. The best oil!

I have been using this oil in my 2015 F150 and 2020 Ford Explorer, since new. Both vehicles are turbocharged. I have not seen any indication of oil burning. This is the only oil I will use in these vehicles, and since I perform all maintenance I have control over the oil products used.

Been using this oil for almost 10 years now

I have been using Amsoil products for over 20 years and never had any failures or related issues. For engine oil I use the Signature Series Full Synthetic 5W-30 and run it a full year which equates to 20k miles in my truck. I use the Amsoil oil filter. My friends think I am crazy for going 20k without changing the oil, but my truck now has 357k miles and never had an engine failure. I notice it does not burn oil using the synthetic compared to the dino juice. Save a little money and buy the gallons instead of quart bottles, plus there is less waste that way.

Engine runs the smoothest with Amsoil. I'll only run amsoil in my cars. Both current cars have direct injection so LSPI protection is high on my list as well. Lab results excellent.

I bought my Dodge Ram used with 35,000 miles on it. A friend of mine suggested Amsoil. Have used nothing else in it. Very pleased with performance.

Switched to this oil and oil pressure has increased in one oil change and cleaned out a lot of my engine parts with first oil change. Lubricants the top end of my engine and no more dry starts

2008 4X4 GMC Sierra 6.0 VortecMax. 129,000 miles I’ve only use this oil since first oil change. Truck was delivered with 4 miles. No engine problems. Change interval I used was 6 months or 5,000 miles.

I switched to Amsoil quite a few years ago after using multiple different top brands. I instantly noticed a difference in how smooth the motor felt in both diesel and gas motors. I would always notice some oil consumption with other brands. Since I switched to Amsoil I never have any oil consumption. The same amount of oil comes out that I put in with oil changes. Highly recommend Amsoil products.

Fast delivery and keep my motor running healthy

Probably the best oil on the market. Have better oil pressure and a quieter engine. 2009 chevrolet silverado
