Customer Ratings & Reviews

Once you start using AMSOIL Signature Series Synthetic Motor Oil and other AMSOIL products, there’s simply no going back. AMSOIL products will keep you hooked, and you’ll want to keep using them for years to come.

I’ve been a preferred customer for 22 years AMSOIL is the only oil I ever use. It’s the best oil money can buy.

I've used this oil for 8 years in my truck. I've had no issues.

Honestly haven't used yet. Going in my 22 Edge AWD 2.0L turbo SUV very soon. Never saw bad review or technical info. Will edit/ update after using product.

Awesome product

Great oil for my Honda Accord.

I use this on a high mileage Matrix, works awesome i don have to refill as before these cars are known for oil consumption

Amsoil Signature Series is always in our crankcase. The engine is so quiet and smoothe. You look into the oil filler and it's so clean you can eat off it. The only oil we use!

Great product!! I will only use this for the built motor in my STI.

I have a 2011 Ford and have been using Amsoil for years. I bought and operated this car in Minnesota for some years before moving south. I am getting the mileage rated for the car as new. When I change the oil and filter it looks clean and the car doesn't use oil.

I have used Amsoil in my vehicles for over 30 years. I have always thought and still think that their products are the best but they have now priced them out of my reach. This is very unfortunate because I will need to switch to Mobile 1 now because of the cost. At $14 a quart for the member price, it is too expensive for me.

Oil analysis proves Oil still well within spec at 12k.

Used on my wife’s Honda crv and we love it! Motor runs super quiet now and can’t wait to see how it holds up to the previous oil that was in it.

It is the only oil I choose to use in my Ram 2500. Wish it was available at my local auto parts store (would probably be more expensive, but worth it) but that's besides the point. I've heard lots of recommendations from mechanics on the interwebs that swear by it and that's what originally drew me to your product. Keep up the good work. I will not use anything else in my truck!

Perfect oil for ALL GM V-8s in our area. No problems with lifters, main bearings, or rod bearings and maintains the Amsoil quality you know from them.

Other than the oil that came from the factory, this is the only oil my gen 6 Camaro has ever seen. Nothing but the best for her!

I’ve been using AMSOIL products in all my vehicles for years and never had any issues. Highly recommended, why take chances when you can get the best from AMSOIL.

I started using Amzoil in my 1984 Square body pickup years ago. With the older engine I tried Mobile one and immediately saw a difference and after a year I heard about Amzoil and saw an even better result and have used it exclusively in all my cars and trucks. I have all 3 of my adult sons using it exclusively and I tell everyone who will listen about how much better my vehicle run with Amzoil.

It’s a great product and I like the delivery… it usually comes in a nice kit with gloves, windshield sticker, and was suppose to receive a tool which I didn’t, that’s my only complaint
