Customer Ratings & Reviews

For at least 15 or 20 years I have been using your products on my vehicles and telling everyone I know about how wonderful the products are. Had my 95 4runner engine re built by my local dealer and thought it was running great. After 200 miles changed to Amsoil and it ran 10 times better. All my vehicles are using your products, from the radiator to the rear end, thanks Amsoil.

Although this quality oil is more up front cost it will save over time. Between the amsoil oil and filter should be able to double the miles I typically change my oil going from 5,000 miles up to 10,000 miles. This is my first time using this oil. So far seemed to help mileage very slightly.

Great product. My number one choice in oil.

great oil

Ames Oil is my No # 1 product for all my equipment. The Best in the Industry.

Will definitely use it again

Best oil in the game keep it up guys amazing work

Oil takes a good beating and stays clean and healthy. Great stuff.

Check out my review on the 0w-20, same thoughts for this weight oil. Far more in-depth

I am certain you may be questioning the title, but by break in I say you notice the most difference or true application of this oil after the third or fourth oil change. Probably once all the crap is out and this is in full lubrication. Been using Amsoil for 3 years now and decided to change when watching reviews of the product performance. It beats out almost everything in the market. Only certain racing line oils surpass it and also cost more. I feel it’s perfect for everyday cars, and have used it with BMW turbo engines to naturally aspirated. I feel it’s best quality is maintaining your engines output for a longer time and excellent for people who don’t drive with pedal to metal. For example most oils work great up to the first 500 miles of an oil change. Engine is fully topped off and the car is providing it’s rated power. Usually after that I see performance decline as the oil cooks. I see with this oil it pretty much holds sold to about 4000 miles and I always top off fluid and my OCI is 5,000 even though that’s way under potential. My oil goes in golden and comes out a light brownish gold. Not burgundy like most cooked oils or dark black. I like to keep my internals clean and don’t mind paying a premium when I do my own work. My strong suggestion would be not go over 7,000 miles even though tests do show very low degradation even after 20,000. Especially if you drive aggressively on a consistent basis.

I’ve been using AMSOIL in my vehicles since before I could drive. Nothing but great performance from any of these products. Quality products for superior protection. I’ll never use anything else.

best oil and service hands down fast delivery and and good prices

Amsoil is the best oil available. Even after 15,000 mi it still is clean and good.

I will truly know when I submit a sample to the Lab - For Real Results ! So far better gas mileage up 10% - even with AC on here on Hot South Florida Vehicle Mazda CX-5 2.5

Excellent product! Keeps my F150 3.5L eco-boost running smoother and cooler in the Summer, and no knocking during start up in the winter. The detergents in the oil really keeps the engine innards clean! I witnessed this along with the dealership, how clean the motor was during my timing chain replacement. The engined looked as if it was just assembled. I am glad I made the switch to Amsoil

Great customer service. Free shipping was a very nice bonus. The best thing is the quality motor oil that keeps my 2008 Lexus IS350 running great at nearly 150K miles. Thank you AMS Oil.

I use this oil in 3 of my vehicles and it gives me consistent 7,500 mile oil change intervals. It is an outstanding motor oil.

I would never wait 15-25K miles to do an oil change, but it is nice to know that Amsoil has me covered in case that would ever happen!

saves me around 3 extra miles per gallon so i end up with an extra 30miles per fuel up. car runs smoother.

I have used many top shelf brands over the years but this my first time using Amsoil and I truly regret not making the switch sooner. The most unexpected benefit which I have experienced is an increase in MPG (the Hellcat needs all the help it can get! Lol) and slightly cooler operating temps.
