Customer Ratings & Reviews

Great product like always!

I have over 400,000 on my GMC Sierra, and this oil outlasts the rest. I have recently changed my wife's vehicle to AMSOIL. She has over 100,000 on her Buick Encore.

Heard about this stuff while working in the auto industry from a friend who swears by it. Did an oil change in my garage at home with this stuff and it appears to be working great so far. I have a 2016 Chevy Silverado 1500 w a 5.3L V8 and it is running VERY smoothly. A little expensive but I know that quality comes at a price. I used the high mileage oil because my truck is at about 95,000 miles. They claim this stuff last 12,000 miles or one year but I will not let it go that long. No complaints, seems to be a great product!

It's the only oil that I put in my 08 6.7 Cummins. The engine thrives, shows 0 leaks, and runs like a sewing machine with 226K miles.

It’s so easy to reorder my kit for my truck and cars. My rep has helped me anytime I’ve needed it. Yes, Walmart is cheaper, but ask anyone in the whole store a question about what’s best for you car and no one can answer you or show you the facts. Walmart doesn’t deliver in my area and I would be weary if they would pick the right products in the first place.

I currently use this in a 2015 Toyota rav 4 with 122,000 miles. Been using the high mileage oil ever since the vehicle had 75,000 miles. The vehicle sees a lot of short trips. The vehicle doesn't "use" oil(not adding an extra oil) between oil changes. In one year we usually travel around 10-12,000 miles

I have found that Amsoil representatives have exceptional people skills. In addition to that, their oil quality is the best!!!

Great price for a great product for your vehicle!

Great product will be buying it for all my vehicles.

I have been using Amsoil products for about 20 years or more. I used it in my Harleys and all my cars. I remember a ball bearing test report that came out a long time ago that made me consider using AMSOIL and I have been using it ever since. I use it in my 2007 350zx as well as my 2024 Acura Integra Type S. I use signature series synthetic, good for 25000 miles, and I change it every 5k miles, I actually changed my oil the first time at 1500 miles, then again at 5k, and now I will do it every 5k going forward to make it easy to remember, 5, 10, 15, 20, 25, etc.. It costs a little more, but instill confidence and makes me feel good, so I don't much care about the added expense, I change the oil myself, so I save a little money there. IMO, better than Mobil 1, Penzoil or just about any other brand out now.

Met my representative Ron at a local outdoor show. I told him that I had been looking to use Amsoil products. He informed me of the products that would fit my application. Helped me establish my account. I placed my first order. Web site was easy to use. Order arrived in a few days, complete and accurate. Last week, I changed my oil. The nice touch was the included thick vinyl gloves and paper funnel.

As always excellent , great products

Ever since switching all my vehicles to AMSOIL I have noticed a difference in performance.

I have been using AMSOIL for over 10 years and have seen better improvement on the condition of the motor and mileage increased a little. Now have over 212500 miles on my Dodge Hemi 5.7 and the only work that has been done to motor is normal maintenance.

I love it that they have the whole package available! I didn't have find oil, then go find my filter. Perfect!

I use Amsoil in my motorcycles and in my trucks I love it would not use anything else. That’s why I have an account and have it sent to my home every six months or so.
