Customer Ratings & Reviews

Amsoil makes incredible synthetic oil, and I wouldn't put anything else in my '20 Ford Raptor.

I have been using only AMSOIL products since 1978! I have recommended the line to many others, who are also totally satisfied, and note performance improvement and much greater reliability.

Shipped quickly, my vehicle’s engine is running smoothly thanks to Amsoil.

Engine runs cooler and with less vibration. I run AMSoil for all fluids on all of my vehicles. Wont use any other brand.

Been using Amsoil for years and now my sons have also begun doing their own mainframe and also use Amsoil. Always recommend for piece of mind.

Switched from Mobil 1 in 2011 Corvette. Corvette runs smoother..cooler...better mileage. Started using in 09 Jaguar XF..noticeable difference. Great lubrication qualities...highly recommend

Amsoil oil filters have kept our 2 Hyundai engines in excellent shape. They are part of the Amsoil oil change that includes Signature 5W20 oil, upper cylinder treatment, and PI fuel treatment. Bought since new, the cars (Sonata 2013; Elantra 2014) perform very well and we plan to keep them as long as possible. Amsoil products and the Amsoil team are offering the best products. They are trustworthy and stand behind their products 100%.

I've been using amsoil since the 80s best oil on the market. I've used all other brands, amsoil wins hands down my opinion, example 77 Porsche gears sticking changed with Amazon oil 80/ 90 weight oil, gears shifted like butter afterwards.

Received the oil quickly and at a very good price, highly recommend!

This is the best 10w-30 I know for a street car for high performance applications such as track days. Redline and Motul 300v is more expensive, and not as good as a street oil. Only thing I wish was that it came in 5quart size as my cars take at minimum that amount

Great stuff that I can trust! It’s definitely pricey but worth the price.

Best oil I’ve ever put in a car. My subaru usually burns a 1/2 of a quart every 2000 miles but since I’ve ran the engine flush and put this liquid gold in. 2000 miles in and nothing is missing. Holds perfect.

Been using this for around 15 years. Love the extended oil change intervals.

Love this oil best in the world will always use this oil for the life of my new truck.

Been using amsoil products for about 3 years now and it always looks new after a oil change and the inside of the engine always looks spotless. I switched my 97 Silverado over to amsoil and now it looks like a new engine under the valve covers

I've been using Amsoil in all my vehicles, for 15 yrs. or so.....and love the extended drain intervals. Although none of my engines have been torn down to check for wear, I trust Amsoil is doing it's job.

stays clean for as long as 25,000 miles while protecting your motor to the fullest
