Customer Ratings & Reviews

I recently purchased a Ford Mustang and I wanted to treat her to the best oil money can buy after my research I chose Amsoil Signature Series.

Just started using amsoil in my brand new engine. Will update at a later date.

Been a long time believer with Amsoil. My Race Team was sponsored from a local sales representative with Amsoil products. I have witnessed its protection first hand.

I use the signature series oil in my Classic Mustang and Corvette and have had great results I would recommend using this in any classic cars

Been using Amsoil since the early 80's. Great success with all products. Current vehicle has 220,000 miles. No oil burn. Still runs like new.

So far so good, my engine actually runs quieter now and running slightly better gas mileage

The quieter sound of the engine was immediate Worth every penny

Easy look up, excellent service and tech questions.

Good product. Quick Delivery.

Simply the best. I do my own maintenance on vehicles. I use Amsoil for everything thing I have, cars, trucks , motorcycles, RV, lawnmower, chainsaws whatever it is its getting Amsoil. Great stuff.

Start out and continue using what works best.

Love all of Amsoil products

It makes you feel good to know you've got the best protection money can buy!

This is the best!

Best oil for my twin turbo genesis

Proud to be a member of the Amsiol Family of users.,extremely pleased with the signature series 0w20 and I always recommend Amsiol products.

You were offering a free item when I placed a big order and Never received it. Haven’t gotten the bill yet to see if my yearly subscription was free with the amount I spent. I’ve got one case of oil that is the wrong weight that I need to send back and get the item I need
