Customer Ratings & Reviews

This is the only oil I trust to run in my Subaru.

Signature Series 0W-20 is excellent quality motor oil.

I first started using Amsoil back in the 70's. I was a Turbine mechanic in Vietnam and knew a lot about synthetic oils. That's why I used it. Now, 50 years later I have it in everything from my air compressors to my street rods. I just bought 2 new Kia Souls, one for the wife, one for me, and a few weeks back I put the 5W30 oil that was selected for the engines in both cars. I usually keep my tucks and cars until they fall apart.. the body's go out well before the engines do. Just a few minutes ago I was looking at the mileage on my 1999 Kawasaki Nomad, 346,000 miles plus and it's still running like new. The last truck I sold had well over that amount on the engine and never used oil and ran great! The 2 street rods I've had since 1990 still have great running engines. Will I use any other oil... NO WAY! I've even had friends change to Amsoil because of how I've proven how well it works. Engine repairs cost WAY too today, so why not use the best oil you can find... AMSOIL!

This is the very best true synthetic oil. Knowing my 6 cylinder twin turbo engine in my Ford, F150 is overly protected is an awesome feeling. Especially in west Texas heat

I’ve been using this oil in my new 2021 Kia Seltos and it not only stays clean, it has lowered my engine temperature. I also use this in my 2007 Toyota Tundra CrewMax especially the transmission fluid. It works so good you can barely even feel it shift. You can’t go wrong with AmsOil!!!! Best oil products I’ve ever used .

As always ams oil exceeds my expectations as its always helped my evo x stay healthy and clean.

Excellent, we use Amsoil in all our cars! Why - because the best!

Works well in -40 to 34C have no worries when beating on the engine or just driving to work in any condition. Great oil pressure and the peace of mind that my oil is doing it’s job is awesome.

Order recieved quikly. All items included. Only oil I will run in my vehicles.

Put this in my daughter's 2011 RVR and she says the car has a bit more jump to it. To me I can hear a noticeable change in the sound of the engine. Be sure to pair it with an AMSOIL filter to get the full benefit.

A really great engine oil if your looking for heat and friction control. I have notice with my car on the highway cruises with ease after the oil change. A must have engine oil. Always quality products from Amsoil.

Tried Amsoil for the first time, and I will never go back to any other brand.

Switched to Amsoil after watching Project Farms oil contest YouTube video. I run it in my Grand Marquis and Hyundai sonata both run like new.

158,000 miles on Ford 250. Run much smoother than Mobile1 that I have been using. Changed my oil 2 weeks ago, took a trip to Florida last week and ran great for 3000 miles

This oil is the only thing that my engine's see for Essential Lubricant for great protection

I do oil changes myself and this last oil change was different. I used amsoil and I felt my car run a little better and made a lot more pops than usual. If you are wanting to make your car run nice I recommend this brand. I am only going to use this oil from now on. Thank you!!

My truck have only 1000 miles so I don't feel any difference, but engine sound quieter.

Ran royal purple one time in my 2019 tacoma and I noticed the engine was louder than normal. After checking the oil and keeping an eye on it I decided to drain it and put in amsoil. After the first few miles I could tell it helped quite the engine back down to how it used to be.

The Amsoil 0w-40 synthetic is the best oil for my Challenger Hellcat SRT engine. My engine burns less oil than with Penzoil that Dodge recommends. With Penzoil, I’m adding a quart between oil changes. No added oil with Amsoil. Dodge should switch to Amsoil like I did!

Used AMSOIL products for over 15 years in cars,trucks,heavy equipment,and 2 cycle equipment.Would not use anything else. Always had excellent service,and good customer support.
