Customer Ratings & Reviews

change the oil on my truck using this 0w20 signature series and I noticed the difference immediately, engine runs smoother plus knowing your engine is more protected especially on those cold starts

Great product and fast shipping times!

Absolutely outstanding oil for lubrication and protection of engine lubrication. I have been using AMSOIL synthetic oils since 1972. I use to teach & work with all types of oils and lubricants for vehicles and aircraft. To compare AMSOIL with regular petroleum lubricants - there is no comparison. AMSOIL lubricants and oils are far superior to any other I have experienced. Absolutely essential in both hot and cold climates for protecting all parts that require lubrication.

I've been using Amsoil in my Kia for 200k miles now and I'm pretty sure that's the only reason it still runs.

I have peace of mind knowing I have the best oil possible in all my vehicles.

I been using Amsoil for years. I change my own oil a lot. I like clean oil. But for my company van it’s a bit different. It gets an oil change once a year with signature series’s 5 30. The van sees hard use and very high rpm’s. It never gets a chance to warm up. I start it and go. Even in the winter. I have never had to add oil between oil changes. I believe Amsoil is the best on the market.

I have been using this product for approximately 20 years, for all my vehicles, I wouldn't use anything else. OUTSTANDING results for my vehicles.

First time using Amsoil so far very pleased will see how it is by next oil change

I use to use Mobil one for years. I tried amsoil in my Harley’s when I rode. The one thing I noticed is the engine smoothed out and ran noticeably better. Then I tried it in my 2012 Camaro SS and the same thing happened. I have a 2021 Nissan Sentra SR now and I have already bought my oil to change when it’s time. Thanks for a great product.

All of use in my 6.4L hemi

It's the best oil that's it

runs a lot quieter will use again

I have been using this oil in my 2012 Corvette Convertible since about 25,000 miles on the odometer. It now has over 130,000 miles and still runs like brand new, with no noticeable loss in horsepower. It also quieted the engine down so I hear the pure exhaust sound. Absolutely love this oil…!

I have been using Amsoil product for over twenty years, and is by far the best product to use, I use it for my cars, truck, and yard equipment.

This is the first time I’ve used Amsoil, and I can’t wait for my other vehicles to need an oil change!

Your website I find your login for suture in your website to be somewhat confusing it took me too long to find the actual product so I wanted

This oil has my car running like it’s brand new and I will use this for as long as I own my car

I have used AMSOIL for years. I currently own a hybrid and my engine purrs on the highway. It’s like running ball bearings in your engine. Try this oil and you will never use any other brand again.

I think Amsoil is a good product but it is a little pricey. I also believe that you get what you pay for. On some test I seen Amsoil beat other products even Mobil 1 EP.

my newest Vehicle is 10 years old and my other older one is 15, and both run like new because of using Amsoil products.
