Customer Ratings & Reviews

I was skeptical at first about amsoil then I researched and read all the great things about there oil and I am so happy I gave amsoil a shot. My mustang is running so much better than when I first bought it and I gained 2 to 3 mpg. I was so impressed by the motor oil and now my transmission and differential now has amsoil running though it.

Amsoil is the only oil used in all our vehicles. It keeps the engine clean even past if for some reason the 1 year or 25,000 miles. My son had his 2012 Nissan Maxima in Nissan shop for work and the Mechanic told him after 25 years working he had never seen an engine as clean as his and it was due the Amsoil oil he uses.

great oil. I have been using it in my 2005 dodge since i got it. Now using it in my 2010 jeep

I have been running this in my 2010 FJ Cruiser since it was new and have zero issues with my engine @ 182,000 miles. My use would probably border heavy-duty / extreme. 7,000 ft. elevation. Mountains to the desert on a regular basis with light towing common. Change it around 10,000 miles. Inadvertently pushed it past that once and the oil looked and smelled the same at change time. Frankly, I just don't even think about or have any concerns about my power train because of this oil. I also bought a 2011 Tundra with the 5.7 in it with 80,000 miles and have switched over to Amsoil Signature as well - same viscosity. When we found the truck, it was kind of an abused pound puppy situation. Of course the dealer who was selling it claimed to have done an "eleven-jillion point inspection", so naturally we get the truck home and find the oil 3 quarts low and black as tar. Changed out and replaced oil with this oil, ran it 2000 miles and used the engine flush product by Amsoil. Pretty alarming what came out that time! The flush product is very effective. The next change however the oil looked normal and I hear very little engine "chatter" which is pretty common for the 5.7 motor. I'm feeling good about this engine despite its previous neglect. I also run Amsoil products in the whole rest of the drive train.....tranny and differentials and have never had a failure!

I believe that if you buy a high quality product to begin with, that you will experience better results in the long run. I can just tell by how well my cars idle and accelerate, that I have found that high quality in AMSOIL. My cars never ran this well before, using other motor oils. I usually keep my vehicles for a long time, and I fully expect them to keep running for a long time, using AMSOIL products! I wish that I had tried AMSOIL years ago. I know that I would have switched sooner.

EXCELLENT PRODUCTS!! FAST SHIPPING!!

First time using this oil in my truck, but I know the products well. I know this oil will give me the best protection.

I use this oil in my Motorhome and it runs great. Need an oil that withstands the demands of my engine.

Signature Series 0W-30 is the only thing I use. I Dont trust nothing Else.

Great oil, must have

I’m using it for the first time now, but if you know what’s being written about it, I’ll be happy and buy it in the near future!

Great Product

Quality oil and very good quality filter.

Amazing AMSOIL quality where these oils stand the test of time. Their product line and reputation prove their quality. I’ll only use Amsoil. Their loyalty program gives you discounts as well.

very good

I have used Amsoil products for many years now. And now that newer engines require thinner oils, I know that our vehicles will be well protected for the long run with Signature Series 0W-20. I don't have to worry about them because I know I am using the best!

👍

This is the first time I've used AMSOIL. The first thing that I noticed was improved fuel economy. I own a 2021 Jeep Wrangler and was getting about 18 mpg combined. I'm now up to about 19.3 combined.

This oil works great and I have been using it for a few years now. Recommend from the GTR forum. -1 star because it does not come in a 5qt bottle.

I purchased My 2016 Mazda CX5 new in 2016. At the 1st oil change I switched from factory to Amsoil 0W-20 because I know nothing is better. I don't buy a new vehicle very often and when I do I need it to last a long. Using Amsoil products gives me the best opportunity for that to be the case.
