Customer Ratings & Reviews

This is a great product that keeps my engine running longer with less oil changes.

I was skeptical at first because every motor oil claims to be the best. I've been running a "purple" oil for years and figured I'd try Amsoil. Let me tell you, the reviews are real. My engine got noticeably quiter and my fuel mileage went up about 30 miles per tank consistently. Just note that the jugs are 1 gallon and not 5 quarts. I run Amsoil in my Harley and will use Amsoil in everything I own from now on. This product lives up to its claims.

Years ago, I had a Dodge Caravan that had noisy lifters. my friend said "Change to Amsoil, and that noise will stop. It did. I have used nothing else ever since in all my motorized machines. Cars, Tractors, Mowers, Power washer, etc. no exceptions. I have had zero engine failures, and am a happy camper. Thanks.

I love this product I highly recommend to everyone,I promise you’ll be saying the same as me right now.

This shipped fast and test results prove it’s as good as it gets. Take care of your prized possessions with the best lubricant you can find. This is the stuff.

I really like the fast delivery of the product that I order. It is rare that I do not get my product within 2 days of ordering. I think when it takes 2 days it is because I have ordered late in the afternoon or evening. I love the product.

Recommend oil for my 6.4 and have had no issues. Price is very competitive.

Both of my vehicles happen to use 0w-20. Never had a problem. I Always use Amsoil oil and Amsoil filters.

I put this oil in everything I have and love it. I use the gear oils also. No oil has ever made my vehicle's engines run so quite and smooth.

I originally rebuilt my motor & used the flush first. My mechanic was impressed never used the products because it’s not available in stores. Did my oil change & added the P. I Booster, really impressed withe performance & longevity.

Superior products! I use Amsoil in everything I own. I won’t use anything else!

Have used Amsoil since 2011 on 2011 Saab. Has 183,700 miles without any engine problems. Would recommend Amsoil Oil to everyone based on my experience.

Great product, fast shipping.

Those who don’t know won’t know! You want the best then you have found it!

OUTSTANDING OIL, I HAVE BEEN USING IT FOR YEARS FOR MY 3 CARS,I DON'T USE ANYTHING ELSE.

I have been using Amsoil since 2001 with no problems and I have been able to extend my drain intervals backed up with oil analysis. I am currently using it on my 2021 F-250 and a 2018 Nissan Armada. On the Nissan Armada I I’m running the signature series for at least 10,000 miles with room to spare all this backed up by doing oil analysis and making sure that you have a good TBN. I’m on my first fill on the F-250 and will be taking a sample at 10,000mi to make sure that I’m still good.

I've been using this oil on both my 2015 Jeep SRT and my 2008 Jeep SRT8 for the last 3-4 years. They both run so smoothly and the longevity of this oil is unmatched. No one comes close in quality to AMSOIL!

I spent years running different oils and comparing quality and performance. Amsoil in my experience performs the best, from below freezing temperatures to high desert temperatures, superior lubrication and wear protection, and all temperature performance to any other oil I’ve tried.

Happy with the product. Engine runs quieter and performs better.

received oil promptly, no issues with shipping. Exact amount of oil needed and proceeded to change without problems, new vehicle for me and was not sure what oil former owners used. I use Amsoil in all my vehicles: 2 motorcycles, 2 jeeps, a truck and a Lexus. No engine issues.
