Customer Ratings & Reviews

I’ve been buying Amsoil for decades. I’ve never been disappointed in the quality. I have a new F-150, I’ll be dumping the break-in oil at 500 miles and using signature series 5W30 (not 5W20). Anyway I strongly believe in Amsoil.

I have been using Amsoil oils for about ten years now. In my opinion this is the best oil for my vehicles. I trust all Amsoil products.

This is top quality oil Would like a change in sales When I just need 1 quart oil should be able to purchase oil in a store for right now usage

Great oil

I have just started using the amsoil 0-40 oil in my 2020Vette, and hope to achieve the results I've gotten in my 2009 Toyota Venza. The Venza has 227,000 miles and we use it as our main vehicle still. I have used amsoil in all my vehicles including my Harley's, Old Oliver Tractor, and assorted cars over the years. Never a complaint. With the additional mileage it afforded me, I believe I have saved hundreds of dollars... Bernard

La consommation d'huile est réduite de moitié... presque nulle!!!

I've been using Amsoil since 2005 and enjoy the added performance to the engines I use it in. Great Product!

I’ve been using AmsOil Signature Series Synthetic Oil in my Raptor and Bronco since they were bought new. Had an incident in Baja with my Raptor that really made me a true believer! A rock put a pin hole in my oil filter. I started smelling oil, but didn’t know if it was coming from my truck, as we were bunched together on a run. My gauges never read low oil, or the engine temp going up, both were steady, even though I lost over a quart! Changed the filter, topped off with more AmsOil, and was on my way. Truck never skipped a beat! Great job, AmsOil.

Can’t go wrong with amsoil products. I’ve switch all my cars to amsoil. Best in the business!!

Excellent products

Noticed difference in engine operating immediately.

Best oil ever made! I highly recommend using it!!

Great product have been using in all my vehicles for years

Great oil, run it in my honda accord 1.5t!

Have ran amsoil in all of my vehicles for a few years and love it, I run this in my camaro ZL1 and never had issues

Outstanding product have been using for over 20 years, would highly recommend this product to every one to use in their vehicle.

Great products with very fast service.

I use this on all my cars. Sure, it's the most expensive offering, but it's absolutely the best. Nothing wrong with paying a little extra for the absolute best engine oil known to man. I won't even think about going down to lower grade Amsoil engine oils. I use the Engine Flush at every oil change together with Signature series motor oil.

The oil and filter are great and make my run better then ever
