Customer Ratings & Reviews

I drive a lot for my job and my engine normally uses 0w20 and changing to Amsoil. Going up to a 0W30 was to me is a good choice. Been using it since my 2022 was new and now has 78,000 miles and no problems engine runs smooth as glass.

There was a lot of positive word on forums and a few mechanics I know. Thought I would finally give it a try in my 3.6l penastar engine. Noticed a difference right away. Engine ran smoother, reved quicker and seem to pick up a little in fuel mileage. Overall happy with Amsoil!

I would Highly recommend it. My son and Husband love this oil for there trucks . My son is the one that recommended this oil. Engines run better with this oil. Its also very affordable. Thank you for your service

Best oil you can buy

I only trust AMSOIL in my vehicles and recommend to all.

Purchased this for my Chevy pick up. It was suggested by other amsoil users.

The oil is top notch! Amsoil is the best! But my experience with Customer Service of this company was very bad!!! I placed an order for oil and then I was given grief for ordering (too much)!!!! 8 gallons. No reason given!!! Still no reason given. I had to explain my reasoning for purchasing 8 gallons and then no reply. Next thing I know my money was refunded with no explanation. I then started searching for other ways to purchase the oil as my husband is a mechanic and oil appeared at my door and money taken from my account after refunded with still no explanation. Very bad Customer Service!!!

Great oil , super fast shipping

Ever since I started using Amsoil, I've gotten better fuel economy in my F150. I drove to Florida from Maryland and was getting 22 MPG, but locally I was only getting 17 to 18 MPG on highway using the regular oil. Reverted back to using Penzoil from Jiffy Lube and my MPG went back down and when I changed back to Amsoil the mileage improved. I'm a true believer in this oil.

Amsoil has always been a leader since its beginning. It out performs, it does its job second to none. It cleans and protects ,it sets the bar for others to follow. It may cost a bit more but isn’t protecting one of your largest financial purchases worth it? It is to me, I want the best for my 50K truck I won’t compromise, this oil has been tested time and time again and has always came out on top. Bottom line…. I love it! Do yourself a favor use this oil or run your motor to junk to soon ,the choice is yours.

I like the research I found the good stuff about it I like the fact that it's flow rate when it's super cold is above all the rest

Love the quality of the signature series oil.

If someone is out there looking for engine oil that is beyond premium look no further. My 2013 Civic SI 2.4L I4 engine has 181K miles still counting and it burns 0 drops of oil. I do 5K mile interval changes and no issues what so ever. I started using this oil for my 2009 Toyota Avalon 3.5L V6 as well, 250K miles and counting no oil consumption yet. For those who don't believe me I will start posting every oil change on youtube. Many are skeptical about my cars not burning oil but I always measure what comes back out and it matches what always goes in. So 5 quarts go in and 5K miles latter 5 quarts come back out.

The product is great. Love the products.

I’ve been using Amsoil for a number of years now. I don’t plan on changing.

Been using this product for 5+ years in my older Ram 2500. No complaints

When I bought my car from it's original owner, he told me he only ran amsoil in it since day one. The car has been tuned and (slightly) modified with some bolt ons and flex fuel, and compared to others in the community, it's held up great. There aren't any amsoil garages or retailers local to me, but I have the same love/passion for the car that the original owner had, so I've stuck with amsoil for every oil change since buying the car 3 years ago. My car loves amsoil, and I'll use it for all future applications/builds. Even if it's slightly more inconvenient for me to purchase locally.. (by no fault of amsoil) than it is to go with other brands :). I've never heard a bad word about this brand, at worst I've heard that "liqui molly is the next best thing". You guys have my loyalty ❤️ thank you :)

Used these products since my vehicles were purchased new. One is 20 years old, the other 26, both high mileage engines run great .

Or recommendation from a very reliable source, I went to the 550 synthetic in my Chevy Camaro 3.6 engine going to add a Tracy Lewis Catch scan soon to really extend the whole life and keep things clean
