Customer Ratings & Reviews

Best oil there is. Makes an engine run smoother.

The viscosity seems to be holding up . Don’t really know since it’s only been a couple of oil changes .

I have used AMSOIL in Texas for over 20 years. It has served me well with long intervals regardless of filter used.

0W-30 oil is a rare commodity in oil offerings. Oil Forums, FB pages are constantly debating the oil issue 0W-20 vs 5W-30 on new vehicles. I understand the 0W weight for cold starts, especially in Montana. However, I also like the 30 rating for towing and turbo engines. I’ll be validating my theory with Blackline oil tests over the next year. I may opt for 5W-30 when Montana summer temps hit.

Our 2008 Toyota Highlander has over 227000 miles on it and still does not need to have oil added between oil changes. Never run any other oil from when we bought the car with 9000 miles on it.

As someone who drives a 24 Civic Si daily, enjoys spirited driving, racks up highway miles, and explores the best curvy roads of the Appalachians, you’re asking a real enthusiast’s question, not just “what’s good oil?” but what oil protects and performs under real-world stress. In that context, AMSOIL Signature Series 0W-20 stands out as one of the best choices on the market

It's motor oil.

I have a 2011 Ford Taurus. I use Amsoil because its a liquid insurance policy for my Ford's engine.

Received oil and filter package super quick. They were packed well. Paul Archer is my sales representative and he has been great to work with. Highly recommend Paul and Amsoil! Thanks

The order was received in excellent condition.

I run this in my 2019 5.0 F-150 and the results honestly surprised me. Before switching, my truck would burn a noticeable amount of oil between changes. After running Amsoil Signature Series, consumption dropped significantly. I also sent a sample to Blackstone Laboratories at 7,000 miles, and the results were impressive. Wear metals came back lower than the universal averages — and those averages are based on about 5,200 miles of use. They even noted I could safely run 9,500–10,000 miles before needing to change it. Between the reduced oil consumption and the strong oil analysis results, I’m completely sold. It’s not the cheapest oil out there, but the performance and protection speak for themselves.

Always get great products at great and fair prices, good delivery time as well.

I believe this to be one of the best full synthetic oils on the market. The previous owner used it in my 2016 Chevy HD and I will continue

Best oil brand and product is great

I have got 270,000 on my truck it has had amsoil since the first oil change motor still runs like new

The Amsoil product works great, prompt shipping and good prices! It's nice to have a product I don't to go search for!

Put this stuff in your car. It works fantastic.

Did my first oil change with Amsoil Synthetic and Insane Diesel Bypass Filter install looking for 15k oil changes. I will be doing oil sample at 10k to see if 15k is doable.

Great oil. However one container was busted and oil leaked. This is frustrating at these prices cause I know the oil is good and want to purchase but since it’s only available shipping, there are no other choices.

Never any complaints about this oil, works great!
