Customer Ratings & Reviews

Outstanding Products and Customer Service. Will not use any other oil products.

Wish I'd started using it along time ago

This oil hands down is my favorite and I will only use it why?because it is the truth!!!

I put this oil in my 2010 Subaru with 125,000 miles on it and I just changed it a few weeks ago. No issues it lasted a year and performed flawless! I can’t wait to put Amsoil in my 2021 Tundra! Just waiting for the free dealership oil changes to expire!

Our third vehicle uses 0W-20 synthetic Amsoil and nothing else! great gas mileage too!

Only synthetic oil I have used in both our vehicles for years now and am amazed at how clean it looks after an extended oil change!

Been using AMSOIL for over forty four years without any problems. I always drive my vehicles like I stole them. Not a better oil on the market. If it works for me it will work for anyone.

The best you can get!

Have been using in my 2004 Chevy Truck for 5 years or more and love it!

Fits perfectly with manufacturers requirements

As soon as I was due for my first oil change, I went with trusted Amsoil products. They recommended this weight in my current car. Even in the Texas temperatures this summer, the car has been performing better and better. On my third oil change now. Throttle response and torque feel great. Thanks for another great product! 12 year customer, will continue to use Amsoil signature series in all my vehicles.

I only change my oil once a year. The oil is amazing. Very high quality

I love using Amsoil for its performance in cold weather. Where I work I do not have access to be able to plug in the block heater in the winter. With the Amsoil I have never had an issue starting the car even at -38C after 8 hours at work.

I've been using AMSOIL in all my vehicles for years. Running the SS 5W-30 in everyone one at the moment. Close to 200k on my Infiniti and the engine is like new. Can't say enough about how great this oil is.

I put a reman engine in my 2009 F150. No issues so far. I like the fact that I feel confident in 10k changes. I have 35K on the reman.

I used to have a rear main seal leak. After hearing the miracles of amsoil I tried it last November and haven’t added a drop of oil for 11 months now.

Love this oil ! I wish I would have found it years ago

Outstanding

Extremely fast shipping and great customer service! They always deliver it fast when I ask for it. And ofcourse great product!

Very pleased with Amsoil 5w-50. It will be the only oil I use in my GT-350!
