Customer Ratings & Reviews

I use amsoil because it provides the best protection for my cars.

Fast service and the oil makes my truck run very smoothly. Very happy with the product.

This is the kind of oil I want to use to keep my vehicle from oil related failures. All oil costs have gone up but good oil pays in the long run.

Should have been using this a long time ago. Did an oil change in my 2013 mustang got premium and could not believe how smooth everything ran. Removed engine vibration and smoother acceleration. Been looking to see what they offer for diesels.

Another great product from a great company

Just put it in and will see how it is. Was recommended by a YouTube content creator.

Been using this oil since 2012 , never had any problems or oil consumption.

Excellent as always

This product worked amazing on my 2017 Dodge charger Scat pack I would highly recommend it.

I switched from the 0w-20 on a Jeep 3.6 and Subaru 2.4l turbo last fall, both motors sound quieter on start-up and when the oil is at max temp. I have seen no reduced MPG after making the change. On the Subaru turbo motor, the oil temps under higher boost/loads are 3-4C cooler and on the 3.6l it has a couple more PSI of oil pressure during low speed high load off road conditions.

I've been using Amsoil since 2001. It's the best oil!

My daily was being used with other synthetic oil brands and was always giving us a sowing sound but that was with 5w20 and now we are border line close to 200k miles and after switching to 5W30 we noticed a big difference especially in the mornings!

I was using 5W20 from what my manufacturer recommends but was told it would be better to run 5w-50 for my 15 Mustang 5.0 and it makes sense since I drive my car like I stole it !💯😎😈 lol but was definitely worth the investment since I do track it several times a year and holds up pretty damn well in the heat and during high revving

Have been running this oil in two Pentastar 3.6 liter engines. Now over 150k miles on both. No problems. Both run quiet and smooth.

Just bought a new 2026 RAM w/3.0 liter Twin turbo engine. Truck runs smooth as butter and oil temps when towing are excellent! Love Amsoil!

Been running AMS oil since the day the truck was borne. Lets see how well it does I have 90k on the truck now without a tic. I've never had a machine that runs AMS it's whole life fail mechanically.

I can already hear a huge difference in my engine.

A great product as usual. I am slowly swapping all my vehicle fluids to Amsoil.

When Toyota posted a bulletin about using different oil in hotter climates and conditions. I immediately went from 0-20 to 5-30 signature series oil right after that was posted. New Tacoma 4-Cylinder Turbo engine runs quieter. Next thing I do is change the rear differential and front differential with severe gear series fluid. Great products I use their gun cleaner and gun oils too. Awesome stuff

I have used this for over 20 years and love it.
