Customer Ratings & Reviews

I will never go back to purchasing from big box stores again...Amsoil provides a premium product with premium service and delivery... it's all that I run in our 2018 4runner, 19 Tundra, 18 Scatpack Charger.

I had 12,000 mile oil tested and the results were surprising as to how good the oil still was. I’ve used this oil for 4 years and my engine has never run better and uses no oil.

very good

This oil works. Improved performance and mpg.

AMSOIL is simply the best, period!

Feels like my trucks run smoother after switching from mobil1. 2010 Toyota Tacoma with 150,000 miles and 2006 Toyota Landcruiser with 190,000 miles.

The oil seems to be doing it's job. Engine sounds the same and runs the same, but I have noticed slightly better fuel mileage running this oil. Delivered promptly and intact.

Heard about Amsoil for years, but never used. About 5 years ago I tried it, and haven't looked back. Run in both cars, and my motorcycle.

Great product, the vehicle runs quiter and smoother.

I always get the product quickly and it has always been correct. I love the products and plan to use this for all my vehicles.

I have been using this oil for a few years now and I absolutely love it. It helps my car run better

I’ve been using this product for five years and it’s been wonderful

I had to settle for the high mileage instead of the signature blend which is my usual oil. But I've been running it now for about a month in my daily driver (Ram 1500) and I do anywhere from 50-100 miles a day. Steep grades, mountainous highway driving, high desert heat upwards of +100°. And this oil has performed better than any other "synthetic" oil you buy at one of the generic parts stores. I don't notice a big difference between the signature series and this one, but I like them both and so does my truck. Last oil change, my oil still looked like it had plenty of life left in it. Which is a good sign. And when I added the new oil (high mileage series) it made my engine run so smooth and quiet. Can't wait for my next oil change when I go back to the signature series! Amsoil for life!

I’ve used this oil for years and I have never been disappointed with it

engine knocks a little with this oil, i put in valvoline max life 10w30 before but never had any knocks!! ?

I run this in my o3 Dodge Ram with no problems.

So far the oil is running good inside the engine there’s no check engine lights or anything.

Best oil for my 2003 Silverado rolling up on 100,000 miles!

5 star

Great product like always!
