Customer Ratings & Reviews

Amsoil has proven itself to our family over many years, and many different applications. Motorcycle, automobiles new and old, pickup truck, garden tractor, garden tools. We apply it to everything we can. The 5W20 has gone into our two Hyundai's both bought new. 2013 Sonata, and 2014 Elantra. Amsoil always surpasses expectations. Stays remarkably clean and right up to the full line on the dip stick.

Excellent service and product

Using 5w20 Signature Series in new Ram 1500. Love the quality of Amsoil products. I can go long chang intervals without worrying about the oil breaking down.

great motor oil as is the entire amsoil line of products

This is supposed to be the best synthetic on the market. Everyone I talk to who are mechanics swear by it.

The Amsoil SS engine oil (5W-20) is a great product to help my aging vehicle drives performed like it was new. I can sense how fluid and effective my car responded to my daily high performances driving habits.

My Subaru is nearing 300000 km with the signature series 5W30 since first oil change. Winter cold starts are easy and not engine issue to report.

I have used Amsoil engine oil and oil filters for the better part of each decade dating back to the 1980s. I have had my vehicles serviced at Honda dealerships since then. Most of the time that I have had a few major engine services performed, I have asked about the condition of the engine and the oil and have always received a positive report. Currently, I drive a 2015 Honda CR-V. I believe that its average fuel economy of ~31mpg in a combination of city & highway driving is attributable to the Amsoil "Signature Series 0W-20 Synthetic Motor Oil" that I run in my CR-V's engine.

I use Amsoil for everything I can.

I use it in my 2500 chevy

Title says it all

Been using Amsoil for around 6-8 years on my 1999 Yukon with 205,000 miles had oil tested about month ago test come back with very good results no probelms at all. The 1997 truck has Amsoil in engine and transmission pulls camper 198,000 miles no issues so far. And all my small engines has Amsoil in them also

I have used this oil product since 2005 and love this synthetic old for the long life between oil changes.

The engine is running smoother and has more pep...greater response!

Have used Amsoil Signature in all of our vehicles/equipment and have never encountered engine wear issues

This oil makes a noticeable difference in cold temperature starts. The engine turns over easier leading to faster starts with less battery draw. The longer time between oil changes helps, also.

I use AMSOIL in all my equipment. Cars motorcycle, diesel work truck, power washer and generator. There is absolutely no way to go wrong using the best there is. So that's why I do it

I strictly only run this Amsoil in all my cars I would never run anything else. I use it in my 1986 Subaru Brat GL, 2002 Subaru WRX, and in my 2009 Toyota Tacoma TRD Sport. I recommend this oil to anyone who only wants the best for their cars or trucks.

Used in a 2016 chevy spark.

Once a year oil changes since car was new.
