Customer Ratings & Reviews

My 2019 Acura RDX with 132000 miles started running real smooth and quiet after I started using this oil!

This is the best engine oil in the industry. You can't do better. Ive tried a lot of the others

Cars performance is always best whenever I use AMSOIL. Very fast shipping as well.

Just what my old truck needs after years of hard work on the farm

Will buy again in future.

My daughter's car runs smoother and little quieter always have had awesome experience with amsoil

I will never go back to purchasing from big box stores again...Amsoil provides a premium product with premium service and delivery... it's all that I run in our 2018 4runner, 19 Tundra, 18 Scatpack Charger.

I had 12,000 mile oil tested and the results were surprising as to how good the oil still was. I’ve used this oil for 4 years and my engine has never run better and uses no oil.

very good

This oil works. Improved performance and mpg.

AMSOIL is simply the best, period!

Feels like my trucks run smoother after switching from mobil1. 2010 Toyota Tacoma with 150,000 miles and 2006 Toyota Landcruiser with 190,000 miles.

I have finally gotten all my vehicles switched over to Amsoil products. I both the high mileage oil for a 2016 Hyundai Santa Fe 2.0T with approximately 117,000 miles. At some point in its past history of dealer maintenance, the dealer didn't notice an oil leak. I noticed a problem when the oil light came on, I added some oil to get my wife through the work week. I decided to do the oil change myself and found where the approximate leak was. I am not a mechanic, but the dealer is BLIND. My wife crawled under and without me saying a word she saw the oil leak. I decided to use what I thought was a high quality high mileage motor oil by a company starts with M and ends with 1 full synthetic. The oil did not slow down the leak, still was putting 1/2 quart in every two weeks. I know I have an oil leak, I don't want to get it fixed at the moment. On to the Amsoil oil review. Lots of research and science led me to Amsoil products. I bought the high mileage oil and did the oil change almost four weeks ago. This is the part I am amazed by, The Hyundai has only lost a little under 1/2 a quart of oil. I have no words to explain this, ,but this made me decide to only use Amsoil for my current vehicles and future vehicles. Thank you Amsoil!

The oil seems to be doing it's job. Engine sounds the same and runs the same, but I have noticed slightly better fuel mileage running this oil. Delivered promptly and intact.

Heard about Amsoil for years, but never used. About 5 years ago I tried it, and haven't looked back. Run in both cars, and my motorcycle.

Great product, the vehicle runs quiter and smoother.

I always get the product quickly and it has always been correct. I love the products and plan to use this for all my vehicles.

I have been using this oil for a few years now and I absolutely love it. It helps my car run better

I’ve been using this product for five years and it’s been wonderful

Changed oil on a Friday night. The next two days drove 1600 miles to pick up a gift from ebay. When I got home the oil was full and same color as new high milage oil I installed. Great trip, great oil. 252,000 plus miles on 2003 Silverado.
