Customer Ratings & Reviews

Engine runs cooler and improved fuel economy

Best oil ever. Using it from day one on my '09 HD, and my 2013 Highlander and 2018 Tacoma V6. My truck gained 2mpg when I began using in 2019.

Amsoil products are terrific. I've been using them for over 20 years and have never lost a vehicle due to mechanical problems. Had 276,000 on my '04 Tacoma and still ran great, until someone turned left in front of me on a rainy night. Amsoil won't help you stop, but it will help keep you going!

Amsoil continues to have products that excel in quality. We’ve trusted our vehicles to Amsoil for several years now and continue to brag on their product.

My Dad started using Amsoil years ago and got me into it. I use it in my vehicles and my boat and cannot recommend a better quality oil.

I've been using amsoil for several years now, and I love knowing I'm protected no matter what

Couldn't ask for anything else in a motor oil

Great Protection for Older car

I change the oil in these two car every 5k or 6 months.

I put less than 15k miles a year in my car so i change the oil once a year.

I use nothing but amsoil products

Been using Amsoil products for 25 years and never a single engine problem, even oil use rate is excellent in every engine I have ever used it in...

I've noticed it runs alot quieter some how. Cuz my mufflers have been a little loud on my Chevy Impala. I didn't see any obvious holes. I don't understand it idles quieter. Passing others has not been noisy either. Just awful good oil.

I've been using Amsoil for awhile now and, as a loyal customer i'm 100% satisfied. Once you switch to Amsoil you'll never go back.

Great product got delivered before I thought it would

Happy with the product

Overall complete satisfaction of the Amsoil Boosted 10w-40. I was turned onto this oil from other enthusiasts to run in my full built/boosted 13 BRZ! Will never run any other brand of oil again.

I use Amsoil products to lubricate every vehicle I own as well as every piece of equipment I own with an engine or motor. I see proof that all of these items get unsurpassed protection. The Amsoil engine/transmission flush followed by Amsoil synthetic oil was responsible for saving me thousands of dollars for an engine repair on my mid-mileage SUV. I won't use anything else! On top of this, I save money over local-purchase products by buying Amsoil every time. Protecting my equipment and saving money is a double win for me.

This is an excellent high quality oil. My mileage has gotten better and engine is quieter.

Got turned on to amsoil through my brother in utah and finally have a car worth running it in
