Customer Ratings & Reviews

I have a Jeep JT with a 3.6VVT with 120,200 I literally have ran the absolute guts outta that motor every sensor has wore out and been replaced and it still holds excellent oil pressure and runs very quite. The Secret Amsoil 0W-20 Signature Series. The very first oil change Amsoil 0W-20 went in and I change every 5000-6000 miles as I work in extreme dust and mud and weather. . Trust me this stuff is the real deal !!!

This is the ONLY engine oil I use on my 2016 SCION iM. NOTHING beats Signature series AmsOil! I am an AmsOil customer for life.

Switched from Mobile and Amsoil keeps my engine much cleaner and quieter

Very great oil for my GTO

This is the only oil I will use in my daughter’s Nissan Rogue. Top notch protection and never an issue with the vehicle at 178k miles.

Have used AMS products on all my cars and SUV's. I would not use anything else.

370z loves amsoil runs smooth

Great oil, I have been using Amsoil for several years. I am very impressed with the technology and development this company uses.

The Best engine oil I have ever used, I use it on all my vehicles. Highly recommend! MORE Frequent Synthetic Oil Coupons and/or Free Shipping would be Awesome and Appreciated 😊.

Works well with a turbo charged engine, provides cooling and protection one would expect and need in the turbo charged engine. We often times drive in the mountains and that is extremely demanding as far as engine temperatures go, this oil is perfect for the demands of mountain driving.

When I was building my performance engine, I researched the best motor oils to keep my investment lasting a long time. After doing diligent research, reading personal reviews, looking at oil analysis results, and talking to people who use Amsoil, I became a customer and couldn't be any happier and my engine would agree.

Get a membership, with all the savings, it will pay for itself. So glad I finally committed a few years back. I use their signature label in my boat, a twin turbo car, and a hard working 6.2 Denali.

After watching countless test videos, customer testimonials and race team results, I made the switch from purple to Amsoil. I ordered an oil change kit for our 2018 Dodge Grand Caravan. It arrived on our porch in 1 day! The van has 95,000 kms on the clock. Gets used for long highway runs because in rural Alberta, nothing is close by! Van lives in a heated garage so cold starts aren't an issue. Short in town runs in the winter are a concern so I wanted the best oil/filter combo out there. Oil change was completed the same day in my home garage as usual. So far, so good. Engine runs strong and quiet as it always has. We'll see what comes in the long run. Next up for the switch is the town car, 2017 Kia Soul EX with 86,000 kms!

I ordered it and have already replaced it. Everything is working well

Just started using this product in a new car. I have already seen an increase in the mpg of the car. Best I have gotten is around 49mpg. Hopefully this will keep the engine clean and running good.

Really impressed. Motor running smother. Increased gas mileage. Highly recommend.

I put my car in storage and when I started it up after sitting for 7 month there was no tickies, like with conventional oil.

Use this in my buddies subaru, even though it'll blow up eventually, it leaves peace of mind that the maintenance has been well taken care of.

I've been using Amsoil products for several years and have had excellant results. I recently purchased a new vehicle and have started using their Signature motor oil with excellant results. The engine is more quiet and performance has been great. I know it seems like a waste to most people, but I change oil every 5000-6000 miles, when I do the oil is pitch black and although many people would think that's a bad thing I believe it just proves the oil is doing what it's supposed to do. It's carrying the contaminants and dirt in suspension. Used in conjunction with an Amsoil filter I feel I'm doing the best thing I can for my new vehicle and I expect ma ny years of reliable service from the engine.

High quality and with stands the heat and abuse my rzr pro xp turbo with 280-300hp can dish out
