Customer Ratings & Reviews

Ive been using Amsoil Signature Series in all my rides for plus 20yrs. I usually keep my cars & trucks 150-200k miles or until the wheels fall off, trouble free, which i accredit to Amsoil. I've used it in vehicles that have had bad reputations for engine/trans breakdowns and had no problems. I highly recommend it.

Great product, been using for years, would definitely recommend!

Great oil, will continue to order as needed

Great oil, will continue to order as needed

Very happy with this product switching all my vehicles to amsoil 0W-20 signature series

Engine runs much smoother than previous oils after 5,000 miles from oil change

Superior product and amazing protection! Your vehicle deserves an oil this good!

When I purchased a new car for my wife I decide to only use the best because this was her retirement car. After all the research I’ve done which was extensive this is the only oil that I will use for my vehicle‘s and motorcycle.

I run this oil in my 2018 F150 5.0 V8 w/100k+, it keeps the motor internals clean. My truck does use some oil, but its due to the high vacuum on the pcv system drawing oil vapor into the intake manifold.

Simply the best there is. My mechanic turned me on to Amsoil close to 20 years ago and I have never looked back. I just changed the oil in my van at one year and 18000 miles. I could have waited longer even though the van has 179000 miles. Being an engineer means I understand how important oil is to an engine, so I will always run the best. Amsoil is the best. Period.

Been using this stuff for about a year now and it’s been great, my engine has never felt healthier!

Have used AMSOIL for 19 years. SVT Focus has 346,400 miles on it. Engine has not been touched. I very much recommend OIL.

You keep sending me promos and I order but do not get any promos

I have been using this oil for years and it always gives me longevity in all of my engines

Good

I've been using Amsoil oil since the mid 70's with many vehicles having turbos. I believe it is the best you can get.

I recommend Amsoil to everyone It make my car run better smoother I love it so much I call it the goal liquid👍👍

I used to use royal purple but only thing I use now is amsoil can't go wrong won't be disappointed

I only use Amsoil in all of my vehicles because it provides the best protection.

Only oil that I’ve used that stopped the cold start ticking in my Jeep Wrangler with a 3.6 Pentastar.
