Customer Ratings & Reviews

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

Amsoil signature series motor oil is what I trust the most for my vehicle.

Best oil in the market

une consommation d'huile pratiquement nulle!!

I noticed the difference immediately my heel runs quieter and cooler this is max oil

Having used a variety of oils in my 2012 Range Rover 5.0l V8 I find a lot of company's will not recommend an oil for this engine. Amsoil do, and they also supply for my other vehicles. Great reputation and I used their products when I last lived in US. Will use 5:30 in summer here in the hot south but my main aim is to protect cam chains and tensioners as much as possible. Early days but we will see and on advice from Land Rover technician will change ever 5-6k. Convenience of one stop shopping for all my vehicles.

Been using Amsoil in my Vette for years. Started using it in my Pick-up and my wife’s SUV for a few years now.

I accidentally ordered the wrong oil - wanted 5W-30, not 5W-50... the distributor gave me a full refund. I ordered the correct oil, it arrived two days later! Great!

First oil change in my 2020 Tacoma since the factory service warranty expired... will give a real review in a year.
