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.

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.

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

This is my first time using this oil I have heard and read a lot of good things. I am very confident in this oil and it’s ability to protect my engine for many more miles to come.

Excellent performance ,improved fuel economy and no consumption in my 2021 Ram Hemi 5.7.

They rook!

Very good product

Great quality oil product!

Been using in my 2019 wrx since brand new. Have 150k currently and have zero consumption or leaks.

I bought a new late 24 Toyota Tundra. First thing I did was a break in oil and filter change at 500 miles. AMSOIL Signature 0W20 and AMSOIL Oil Filter. Every 4 to 5k.
