Customer Ratings & Reviews

This is the only oil I will ever use. Love the extended change intervals keeps me from oil changes in the dead of winter. Cold weather starts are never an issue, -20+ below zero and my vehicles turn over like a summer day.

I am a parts manager at a local agricultural dealership and am keenly aware of both the high quality and the snake oil products that are out there. From my experience, Amsoil is the cream of the crop. On Christmas night 2009 my wife's '02 Silverado (used Amsoil 5W-30 since new) which had a little over 169,000 miles on it at the time broke a valve spring on the #6 intake valve (not an oil related failure). We took it to a local shop for repair and when we picked up the truck after the repair the shop owner showed me the failed parts and they were as clean as a new part. I inquired about engine cleanliness and he stated it was as clean as a new engine. Confirmation of money well spent. I'm still a preferred customer and still a loyal user.

Another “home run” product from Amsoil. Buy all my vehicle oil change, fluid replacement products from Amsoil. Best on the market!

It works as advertised. Never had an oil related problem using Amsoil.

I’ve been using Amsoil ever since I got my 2018 mustang GT. The engine runs super smooth and even quiets down a bit that typical tick from the third generation from the Coyote.

Using this and extended life oil filter on a 2012 Honda Crosstour since it's first oil change. Wouldn't use anything else.

I've been using Amsoil for a couple of years already and I've been very happy with this product. My engines feels smoother and quieter than before plus I know I'm getting the best protection for my vehicles.

Is the best oil on market

First time using Amsoil. All my oil changes before I used Motorcraft in my 2014 mustang. With Amsoil my car starts easier, idles better, and seems to better performance wise. I will never use a another oil in my mustang.

have used Amsoil in ALL my equipment costs a little more but I save in the long run don't have change oil as often my chrysler pacifica calls for 0w 20 will be able to run this for about 15-16 thousand miles which about a years worth of driving for me I totally believe in Amsoil products

I notice a difference in the way my engine runs; very smooth. And this product is not much more than the high quality synthetics like Mobile One but much better. Glad I found out about these Great products.

This is the only oil I use in my dodge demon & hellcat & srt durango. It’s that good!

The best product and recommended by several mechanics!

Engine runs smooth and quiet. Never an issue. Products are delivered quickly and of top quality. Every engine I have run it in from Corvettes (5w-30 Sig. Series), to daily drivers (0w-20, 5w-20, 0w-30, 5w-30 all sig. series) and outdoor power equipment (small engine 10w-30) I have been impressed. Smoother, quieter, oil temps. slightly cooler and longer drain intervals make it worth while.

For my first time ever buying and using amsoil, I've got to say, I'll probably never go back to anything else again. Best motor oil I've ever bought!

My engine ran sooo much smoother. This is my first time using it, and i won’t ever use another oil. High quality for sure!
