Customer Ratings & Reviews

Excellent products! If you want your vehicle to last longer and maintain performance, use this product.

Great oil!! Definitely holds up to my lead foot. The wear protection and mileage you get out of this oil is great.

Been using the Signature series oil in my daily driver for 8 years. It really saves you money in the long run because you’re only changing your oil 15k-25k depending on conditions. Car has over 200k on it and still has plenty of power just like it did when it was new. I will always use the signature series oil.

Great product

I've been using this product since I purchased my 2016, Ram Power Wagon. Even when the dealership makes the mistake of using their oil I always thank them for the engine flush, butt use the oil I brought. Never have I had an issue with my truck while using this product, no knocks or ticks just a smooth running engine just like the first day I cranked her over back in May of 2016. My truck now has 176k miles and is still running smoothly. I recommend this product if you care about your vehicle.

Amsoil makes the very best....synthetic oil! When you pay big bucks for your performance motor, you need to protect your investment. There is no better way to do that than use Amsoil products!

270,000 klms on my 2017 hyundai Santa Fe with the GDI engine using signature series and P. I . injector cleaner. Runs like new!

It is a quality oil with the testing and science behind it. Been running AMSOIL in all my vehicles and they run great. Noticed a difference in engine cleanliness and performance.

Just started running this in my 2021 Civic Type R with 5,500 miles. After mods and tuned had to put some Amsoil in. Great stuff, thank you!

Glad to do business with amsoil

Excellent performance, great price for the value, and the engine runs better and with less effort. Truly the perfect oil for any application, sports car, truck, everyday driver, and classic.

Best oil I have ever used. # Canadian Winters

I saw a comparison test been done with all the Synthetic motor oils and I was surprised that the oil I was using for my vehicle was not even close to the top of the test, but this Amsoil was. When I purchase a new F150 in 2019, I replaced the original oil with Amsoil and never looked back. I have over 200th on the truck now this engine runs perfect. I do oil changes every 20,000 km and never see any metal particles on the pan. I would recommend this to everyone.

I have Amsoil in the whole drivetrain and plan on getting lots of miles out of this vehicle.

Have used this product for many years in my Toyota Highlander. I highly recommend it.

This oil holds up to everything you can throw at it and in any situation. I highly recommend it for all vehicles.

I've been using 5W-30 Signature Series oil in my Toyota Tacoma since I bought it new in 2012. I now have 240,000 miles on my truck and it's still running strong with no maintenance issues. I strongly recommend this oil over any and all OEM oils.

The only oil I use in my vehicles and equipment.

This is the best oil I've ever used. I have much better oil pressure in my 2009 chevrolet silverado. It should help with the lifters.

Use their oils in my track car and two others. Have sent half a dozen samples for testing and always great results. I could easily take the oil a lot further. But I’m about the cheap insurance when it comes to performance.
