Customer Ratings & Reviews

I love this oil. The SRT 392 Hemi runs great with this oil. I would recommend this oil to anyone who has a Scat Pack or Hell Cat Challenger or Charger.

I changed from Mobile One and have been very pleased with Amsoil. Not only their product, but their service has been outstanding, too.

If you are reading this, just buy it and try it! This oil is making a difference in all my vehicles. It has greatly reduced engine noise and smoothed out. I have watched many videos and I highly recommend the Gale Banks episodes he did. Thank you Amsoil for putting a superior product on the market!!!!

Love the quality and savings of extended Milage oil changes. Been using Amsoil for several years now.

I've watched so many different videos about people's experiences with AMSOIL that I just had to try it. My cars, 2013 Odyssey and 2015 Pilot both are running 0W-20 Signature series oil. It just gives me great comfort that the engines have this type of quality. I know this oil can go the distance of 25,000 miles but I will most likely change oil and filter every 12K miles or so. I am servicing the transmissions next with AMSOIL trans fluid on both vehicles. I'm sold on it.

The best oil for any application worth the extra $

Great product. Oil pressure seems better, 05 silverado with 250k miles

I always go around a full year between oil changes, and the mileage is usually from 22-24K. Te proof is in the pudding. Used oil analyses consistantly show little if any wear metals, TBN of 3-3.5, viscosities are still well within range, and flash point >420. Can't think of any reason not to use this oil. I've used Amsoil products in everything from my vehicles to my diesel tractor to my 150hp outboard. I've been using Amsoil products since they were first introduced in the late 70s/early 80s.

Never reach the expected change interval. Oil was very dirty, so maybe it was doing its job….

I’ve run Amsoil 5W Signature Series in my ‘21 Chevy Malibu since I bought it a year ago. I use this car to commute to work, traveling 160 miles daily on an interstate highway. The car has the 2.0 Ecotec engine for over 35k miles in the past year. The engine is turbocharged and a very good oil is need with that. I’ll continue to use the 5W-30 Signature Series in this car for as long as I own it. Amsoil makes superb lubricants and I’ll continue to use them. I also like that Amsoil stocks very high quality oil filters for my vehicles. Great product and seller. I’ve given them five stars and an A+

We run the 0W-20 in my son’s 2018 Toyota Tacoma pickup. The signature series exceeds Toyota specs for engine oil and we’ve been happy with the results. You can run this oil at extended drain intervals without fear of the oil degrading and breaking down. Great product that we 100% believe in. The engine runs quieter with this oil in the crankcase. I’ll give it an A+.

I’ve been running this 5w 30 in my drift car with crate ls3, after about 1,000 miles and a dozen events I did a cam swap. There are no visible wear marks on the stock cam after a ton of abuse. Run the 5w 40 in the 6.7 powerstroke, have noticed smoother and quicker start up’s.

I’ve been using Amsoil for years know, this is the best oil manufactured today. If you want the best engine protection use Amsoil.

I want thanks ams oil with there awesome and service and keeping me up to date too

I have been using AMS Oil in all 3 of my 6.4 hemis. AMS oil meets Chrysler specifications, but most oils do not even if it’s the correct weight oil. You do not want to damage your engine and have costly repairs. I use AMS oil and have had great success with it and perfect running engines. Do your research and request AMS OIL.

Amsoil is the best motor oil I have ever used.

In my opinion the best.

The best oil money can buy.
