Customer Ratings & Reviews

I will not put any other oil in my cars.

Want the best, buy AMSOIL

I use the Signature series oil in a broad range of vehicles, from my 04 Titan to a 2018 Chevy cruise. I love the extended change intervals and the security of knowing that my vehicle is protected. You cannot beat the customer service either.

Best oil you can run. Period!

Need this for my Toyota, I commute for work and this is a better price product for the amount of mileage it is good for.

I have a 2013 Subaru Impreza bought it used from the dealership in 2017 with 69,000 miles. Two weeks after that I started using amsoil motor oil and filter.

Great product.

The Best oil, period!

Makes my car happy

Good Stuff

Great oil! Stays cleaner and our cars run smoother with a lot less top ups like the extended drain intervals!

Great oil for mail Jeep

Great products as always from Amsoil.

There is nothing better made. Top of the line!

You cant really tell the difference between having your oil changed Religiously and putting amsoil to be honest, I mean your car will respond just as well, but the fact knowing that amsoil is up to 4X better than conventional synthetic oils, is a big peace of mine for me

Great product!

Simply the best. On every daily driven car that comes through my shop.

Have used this oil for many years and love the fact it keeps my engine system clean and that only have to change every 25,000 miles. I use nothing but Amsoil in all my engines. My kids use nothing but Amsoil products in all their engines, vehicles and small engines.

Have been using Amsoil 5W-30 motor oil in my 2008 H3 Hummer since new. Great product! Absolutely no issues and the extended oil change intervals are a big plus to me.

Used this in my 2019 Tundra
