Customer Ratings & Reviews

It’s very high performance for my minivan during highway driving over 85 miles per hour. It feel like the minivan has no friction and great momentum! Use it for few years now. It not up to 25k mile change interval but 5 k mile for my high mileage.

Been running Amsoil for many years. The FJ has 290K on it with no leaks and not one bolt has been removed from the engine for any repair. This oil works with 25K oil changes.

The best oil Engine protect More power More miles

Always used this product on all my vehicles love all the guidelines especially with my turbos on my 2020 F150 Raptor would recommend this product for every one #1

Been using Amsoil Signature Series 0W-30 pretty much since it came out. Used it in place of 5W-30 in my 1987 Toyota Tercel Station Wagon 4WD (250,000 miles at present) first. Now also in my 2013 Toyota Matrix AWD in lieu of the 0W-20 it calls for trying to prevent the oil consumption that engine is known for. So far over 145,000 miles with excellent gas mileage and no oil consumption* (1/2 quart of oil used several times around the 5500 mile mark). Not too shabby! I recommend it highly, but for "safety" reasons stick to your recommended oil viscosity. But of course - Amsoil

I swear by the amsoil signature series run it in everything I own

I receomendes

I have been using AMSOIL for 7 year. I use Amsoil for my Tundra and Dodge 2500 HD Diesel. I will never go back to using the standard oil that is sold at stores.

This product is outstanding. I use Amsoil products in all of my vehicles, and have been for many years. I experience no lubrication related issues with my vehicles. I will always use Amsoil products in all of my vehicles.

This is a great performing oil. Enables my car to start in sub zero temperatures. I feel I have great protection too and get slightly better mpg. Only reason for four stars instead of five is the cost. It's getting expensive. I have used Amsoil products since 1998 and have been very satisfied.

Only oil I put in our three vehicles. Will not use anything but the best

I really recommend this oil if you want extra protection for your engine.

Best oil and filter on the market today. Great service and fast shipping, highly recommended.

Could not be happier with quality of oil. 10 year old car is running smoother now than it has for years.

The amsoil products are 2nd to none, they always surpass expectations and ordering is fast and efficient

Absolutely love your product. I have been impressed running it in my vehicles and I’m very picky haha. I will try it in my 1972 charger next summer as well.

This oil is amazing, my car runs so much better with this. It is a little pricey but worth it. Since it is expensive I decided to switch from it to the dealership brand oil in my Corolla since it was a few dollars a quart cheaper. I figured since it was Toyota brand it’s gotta be good right? I could tell the difference immediately with the Toyota brand oil. The RPMs ran higher at idle and the engine made a clattering noise when I would accelerate. I switched back to Signature series in 1,000 miles. Everything quieted down immediately. When I pull up to stop lights you can’t hear the engine at all, no more clattering when I accelerate. I’m thoroughly convinced that this oil is the best there is.

Have been using this product for years, change it every 10,000km engine is perfect and also no sludge build up. Great product

My vehicle engines (2011 F-250 6.2 gasser & 2008 Harley Ultra Classic) run smoother, cooler and quieter using Amsoil products. I will never use any other lubricants other than Amsoil in any of my vehicles. And when I do oil changes, I get every drop back!

Best oil in the market hands down. Worth every penny due to the benefits of this oil. I used to use Mobil 1 on my car and it just didn't feel right. Then I gave amsoil a try and never looked back. My cars engine feels so much better than before.
