Customer Ratings & Reviews

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.

Brand new Kia K5 GT nothing but the best for her, with the help of amsoil this car will be arounf forever gonna break the kia stigma, lol thanks for the best oil ever amsoil ily 😘

I use amsoil in all of my vehicles. I feel that is why I obtain high mileage with little or no major maintenance problems. My 2003 Chevy truck now has 347,000 miles with no engine teardowns. It still runs like a top. My 2023 Envision with only 47,500miles I had oil change recently. I expect high milage on it also. It's not just synthetic, it has to be amsoil synthetic.

Fantastic! I switch over to AMSOIL Signature Series 5W-30 at 30K service, my trucks seems to be running smoother, I intend to stretch out my oil change to 7,500-10,000 mile instead of 5,000.
