Customer Ratings & Reviews

I’ve trusted it for 15 or more years and use everything from the gun oil to break in oil

Everything runs smoother, cleaner and longer. Years of Amsoil products especially the oil specifically has been proven to me over the years.

I've been using this oil in my motor home for years. I go across country and for me it seems like this oil will go go quite a bit longer than others.. I seem to get about a 1/2 a mile per gallon more I've tried other oils and they just don't seem the same..

There is a reviewer online called "Project Farm" who I respect very much. He did a really scientific test on motor oils and AMSOIL Signature Synthetic absolutely dominated the competition against all the other motor oils. I have bought two new cars, a Honda Accord Hybrid Touring and a Toyota Tacoma 4runner Premium. My strategy is to own reliable vehicles, use AMSOIL's Signature Series oil and have a meticulous maintenance schedule. I Believe, following this plan, my cars will outlive me.

Used this stuff on my Nissan 350Z and I've been using this stuff for years. Definitely, recommend.

Oil samples always come back great

The engine runs smoother at startup and cooler at the track then the 10W-60 recommended by the manufacturer.

I love this product

I have a 2018 F150 Ecobeast, I just changed to Amsoil with a WIX XP oil filter. Next morning I noticed better performance, engine ran and runs smoother and feels better! I highly recommend amsoil for all engines and drive trains. I will be switching all my vehicles to Amsoil products. All fluids!!!!

I use Amsoil Signature Series 5W-30 Synthetic motor oil and Amsoil filters in my Generac 27KW generator. If the generator doesn't run in a power outage, it becomes an expensive lawn ornament! With Amsoil, I am confident the engine and generator will perform as expected. and under any conditions

AMSOIL is awesome. The day i bought my car, new off the lot, I changed the oil to Signature Series 0W-20 Synthetic. The one time a knock sensor went out and I took it into the dealership, (118K miles) the mechanics asked if had the engine replaced because everything looked new. Now I am at 195K with the engine still purring like a kitten. Once a year oil replacement and every 5-7K miles filter replacements has kept my car's engine in great shape!

ALL AROUNG BEST PERFORMER FOR ME

Great oil, works as advertised, and I always appreciate how easy it is to order from AMSOIL. Used this in my old car for years and never had an issue. Just swapped to another vehicle and plan on using it for the life of it which will hopefully be longer since I'm using this oil!

I been using it for more than a year and is been excellent oil

Awesome product

At least you know what your putting into your auto.

Oui je recommande ce produit , je l`utilise dans ma toyota corolla 2006 et j`ai remarqué une grosse différence au point de vue performance , moteur plus propre .

Great products high satisfaction

Trusting Amsoil research for a number of years now. All my gas vehicles and my cummins diesel truck. I drive under 20k per year in them all so its one and done per year. Also use other Amsoil fluids and am pleased. Worth the slightly higher cost to me.

Always look forward to doing oil changes with the best oil you can get. My vehicles always run better with Amsoil. I tried different oils in my street bike and it did not shift the same.
