My 17 year old engine has never run quieter or smoother

This oil is perfect for my 800 hp Mustang! I love it! Trust AMSOIL will protect my car to the furthest extent!

I have been using AMSOIL motor oil for many years, at least since 2014 maybe earlier. I had read about a ball bearing test and very good results, so I decided to tr5y it in both my Harley and my Nissan 350z. Both ran very well and seemed to like the Amsoil. I usually use either high mileage synthetic for my Z at 170k miles or in my Harley and newer cars signature series. I just changed my oil yesterday at 10,000 miles on my 2024 Acura Integra Type S. this high performance 4 cylinder is fantastic and is a high revving engine, so it is important for peace of mind to have the very best oil in there I can. I changed it at 1500 miles, after break in then again at 5000 miles, and now a 3rd oil change at 10kl miles. I feel very good about it. My car runs excellent and after new oil, filter, and air filter it seems renewed, and healthy, it just feels good to know I have new Amsoil in there, good for 25k miles and it will never see more than 5000 miles in my car. Engines are expensive oil not so much, change it often.

Oil does make a difference. The car runs smoothly and feels like less effort is needed in accelerating.

Great stuff

Will install with my next oil change and will never turn back. I believe in the technical advantages of Amzoil 100 % synthetic. Why? I intend to keep my new car a long time. This product offers resons why it it is a superior product.

This is the best oil in the world. I’ve used this product many times and very happy with the results.

Love this oil, really have noticed my 03 lancer ES run smoothly.

I simply ordered the kit I needed and it all came in one package. Once I clicked on the pay now it was here really quick. Everything I needed was in one box and neatly packaged. I'm only on mile 120 but so far so good.

I use my truck... I put the 25k AMSOIL but change the oil every 10k.

Over 20 years of using Amsoil with no engine failures, improved mileage, and negligible engine wear. I won't use anything else.

I've been a royal purple guy for 20 years. I was doing some research and decided to change to Amsoil. I've seen a noticeable difference in engine performance and better fuel economy. I would highly recommend this oil.

Great brand excellent product

I’ve used this product for 40 years without fail. I have a couple of high compression motors that I want to be sure gets the proper lubrication. This oil never fails. both engines run well and never overheats, or seem like they’re straining. fast customer service from Amsoil as well.

Well worth the investment. Best performance oil in the business.

i got this based on all the reviews and claims that its the best. i saw it win a pour out race at -30degrees on youtube against another brand haha

We did the first (10,000km) oil change on our new Subaru Forester. To my surprise, immediately subsequent to the change, the fuel consumption dropped from 7.8 l/100km to 7.2 l/100km. The savings in fuel costs will offset the premium paid for Amsoil.

Great stuff!

I was turned on by Amsoil ever since I went to SEMA 2024 and had the opportunity to speak with an Amsoil representative. I forgot the lady's name but she was helpful, answered my questions, and very nice. When I went to the Amsoil website, I was taken back by all the products available, and the fleet management system on the site. I was sold, I bought several kits for my vehicles, and will continue using the products. Thank you Amsoil. You're the greatest.

Great Service. I love the convenience of working with you guys.
