Customer Ratings & Reviews

Only oil I've ever used (synthetic or conventional) where I immediately noticed a difference in my first drive. Car runs smoother, accelerated smoother, and is quieter than ever before.

I love AMSOIL. I have changed all the fluids in my truck over to AMSOIL

I have been using AMSOIL products for at least 43 years. I won't use anything else given a choice. It's everything they say it is and more. I use it in everything that requires oil or grease. I have complete confidence in AMSOIL. All of their products do as they are advertised.

I believe in synthetic oil. I want the best I can get at a reasonable price. Considering I can get free shipping to go with it. Delivered to my door. Amsoil gets great test reviews. How can you beat that. My Victory gets real hot when stuck in traffic, so I want an oil that can stand up to very high temperatures.... great stuff

I have used Amsoil Oil and filters in my equipment and feel the engines run smoother ,cooler and last longer along with extended oil life .

Annual oil and filter changes are great and convenient.

I've been using amsoil products for the past 40 + years and will continue. They been reliable and I don't care if anybody wants to sell me cheaper products Amsoil will always be my number one choice. I do dragsters,motorcross,heavy towing, performance boating, even the wife's car and some of my coworkers vehicles I get products for

We have 2 2004 Chervolet Duramax diesel trucks. One has more than 500,000 miles. All we have ever used is Amsoil products. Will not use anything else.

I use this on my 2010 acura tsx. It has 210000km now and the engine is clean as a whistle inside.

I started using Amsoil in my vehicle and notice the difference compare to other motor oils. The oil is great and the oil filter are also great to use.

No doubt if you want the best you must use Signature Series. Unmatched protection and longevity for a great price.

Good quality filter to go with the best quality oil!

We have used Amsoil exclusively in our business fleet of Ford Rangers for around 20 years . We have several trucks with mileage over 300,000 that are still being driven everyday. These trucks will eventually disintegrate around a fine running motor. We park outside, cold start them at -30 and run them hard at 100. Have never had a major engine issue with Amsoil.

Premium quality, far better analysis than other competitors

Build quality is good. Oil strays clear for longer.

I use Amsoil products in very in every engine I own from my lawn mower to my bucket truck. At last count I was using Amsoil in 22 different engines, plus their gun cleaner and oil.

I've used Amsoil filters in all of my vehicles from diesel pick ups to performance cars and my 4 cyl. SUV. The extended use and excellent quality allow for less frequent oil and filter changes and even with the high miles that I drive, the protection in all conditions is far better than with other filters. I'll continue to use the Amsoil line for all my lubricant needs.

It's long lasting and my car never once has complained about it.

Easy upgrade to the factory filter. Wouldn't buy any other filter to help protect my engines.

I'm new to Amsoil but a bunch of my friends have used it a long time in their street cars and there HPDE track cars. I just put it in all 3 of my cars along with the Ea filter. So far I am very impressed and I plan on using it from now on. 2 of my cars are direct injected turbos and I wanted the better protection over Mobil1.
