Customer Ratings & Reviews

I use Amsoil in my wife's Jeep Rubicon and it keeps the engine protected from all the 4 wheeling we do up in the mountains. We call Amsoil the good stuff.

Very good oil and the price is great fast shipping and customer service is awesome!

Love Amsoil and have for years never a problem.

My opinion best oil out there, low oil burn off, haven't had reason to get into the engine internally for looks, stays the cleanest I've ever had on the dipstick for longer miles though. Highly recommend!

After being a GM vehicle brand user for many years I started noticing performance issues while using Mobil and other large name brand oils that promised best engine oil performance available, WRONG! As many know of the sludge buildup in GM DI motors as well as the fuel management systems collapsing I switched to Amsoil Signature Series and immediately noticed a smoother running engine, better mpg’s and overall performance was just as good 5 years later and with 100k miles later as it was on the day I bought it new. If you want peak engine performance and outstanding reliability then I highly recommend using Amsoil 100% synthetic engine oil and filters. Better for the environment too as less oil changes, less chance of spills.

Love the product. Always fast and convenient shipping times. Highly recommend

Great oil and fast shipping!

I use Amsoil in my boat, truck, cars, small equipment as well. Great to deal with, fastest of shipping, and may I add, the best protection available with Amsoil. 👍🏻

Excellent product, top quality in all tests I have read. I use it in all 4 of my vehicles. However, at the prices charged, shipping should be free on all orders.

The best once a year Synthetic Oil money can buy! Been using Amsoil products for over 20 years.

Use this oil both in my van and car, vehicles both run great, get as good mileage as you can get out of a van and could last the year. I change every fall and spring .

Using this stuff for over 200,00 miles on a ‘12 FJ Cruiser. No issues, leaks or troubles of any kind. Use it in my Tundra, 175,000 miles and change it every 25,000 miles. Money savings!

Been using AMSOIL for years and really like it. when I order it bam it is here! I also like the free shipping for orders $100!

I use this oil often because of the 25000 mile guarantee. I have not tested for a full 25000 miles, but have been close to the year mark without any issues.

I’ve been using Amsoil for a long time and can say that without a doubt it’s the best quality oil in the industry by a long shot. I use it in every vehicle I own, good quality engine oil is a must especially in newer GDI Engines. There just isn’t any better in my opinion. I’ve worked in the auto industry for over 20 years now and you absolutely get what you pay for.

I have been using Amsoil since 1985. I currently use the 5-20 signature series in my Toyota Tundra since new. My truck now has about 60k miles on it. My last oil change was about a year ago and I have added about 6k miles. Oil looked almost new. Amsoil shipped my oil to me and arrived 2 days earlier then anticipated. Obviously will continue to use Amsoil products

Amsoil is the best Motor oil you can buy can you go wrong with it and I’ve never had any problems using any Amsoil product I have in my both of my cars my motorcycle my lawnmower my snowblower my power washer put Amsoil products in everything you’ll never have any issues believe me I’ve been using Amsoil for over 25 years
