Customer Ratings & Reviews

I really recommend this oil if you want extra protection for your engine.

Best oil and filter on the market today. Great service and fast shipping, highly recommended.

Could not be happier with quality of oil. 10 year old car is running smoother now than it has for years.

The amsoil products are 2nd to none, they always surpass expectations and ordering is fast and efficient

Absolutely love your product. I have been impressed running it in my vehicles and I’m very picky haha. I will try it in my 1972 charger next summer as well.

This oil is amazing, my car runs so much better with this. It is a little pricey but worth it. Since it is expensive I decided to switch from it to the dealership brand oil in my Corolla since it was a few dollars a quart cheaper. I figured since it was Toyota brand it’s gotta be good right? I could tell the difference immediately with the Toyota brand oil. The RPMs ran higher at idle and the engine made a clattering noise when I would accelerate. I switched back to Signature series in 1,000 miles. Everything quieted down immediately. When I pull up to stop lights you can’t hear the engine at all, no more clattering when I accelerate. I’m thoroughly convinced that this oil is the best there is.

Have been using this product for years, change it every 10,000km engine is perfect and also no sludge build up. Great product

My vehicle engines (2011 F-250 6.2 gasser & 2008 Harley Ultra Classic) run smoother, cooler and quieter using Amsoil products. I will never use any other lubricants other than Amsoil in any of my vehicles. And when I do oil changes, I get every drop back!

Best oil in the market hands down. Worth every penny due to the benefits of this oil. I used to use Mobil 1 on my car and it just didn't feel right. Then I gave amsoil a try and never looked back. My cars engine feels so much better than before.

Great product!

Been using Amsoil oil in my vehicles for years. I had to replace the timing chain and related components on a 75,0 00 mile Honda Accord Sport, which required the timing and valve covers removal. I was shocked at how clean the engine internals were. No sludge or residue anywhere. Looked like a new engine. That sold me on Amsoil Signature motor oil. Started using the Amsoil 0-20W Signature oil because it was the highest rated oil for a direct injection engine that I could find, and it sure paid off.

This will be the 6 Amsoil oil change on the jeep. Usually I buy the larger 2 gallon jugs but I'm still sitting on some, sobI went with a quick 5 quarts

Confidence!

Besides, being a top oil in the industry, the shipping was outstanding. Not only did it come in a timely manner, but the oil was packed with great care. Plenty of padding between the jugs, made them arrive in perfect condition.

Well this is my first oil change with Amsoil products. So far so good. The engine sounds happy and healthy. No ticks or unusual sounds. I will continue to use them.

Been using Amsoil for 28 years and will continue using it. I use it in my car truck(cummins) tracto and mower both with Kubota diesels.

Best synthetic oil ever, I have used others once. But with Amsoil, I been using it for years.

I HAVE BEEN USING AMZOIL FOR OVER 48 YEARS IN ALL MY CARS AND EQUIPMENT. IT THE BEST OIL IN THE WORLD.

Awesome product and gives great protection

I didn't think my '08 AMG could sound or run smoother, but then I, on my first oil change, I used my much-loved Amsoil. Now the beast (as my wife calls her) purrs like a sweet 500+ hp kitten. I also noticed a small fuel mileage increase, and during the hottest months no oil consumption (as the prior owner had noted).
