Customer Ratings & Reviews

I change my oil once a year roughly 12,500 miles

We use this product in all my Jeep Cherokee Sports 1999, 2001, 2003 Grande Cherokee, and a 2004 Durango SLT 5.7 Hemi. They all run great and have a lot of miles on them. We also have a couple of old race cars and use it in them, if we get them out. We are hard on our cars and use them we are not granny drivers by any means the 2001 Cherokee only has 157,000 on it but we are going to start to use it daily as of tomorrow. the others are all used every day.

I Like the throttle response with Signature Series Amsoil !

Order was easy. Shipment was right. Product is great. Customer service was awsome.

I believe this to be the best motor oil.

Great quality oil and filter - less oil changes and the perfect protection for the engines on my vehicles.

Shipping was prompt and everything came in as promised

I aways use amsoil products after I used this oil in a car of mine that had a ticking valve when it was cold for carbon buildup The Tick went away never came back.

It has been working excellent and we will always recommend this products to our friends and family.

5.3 engine in my wifes `16 Suburban is smoother and quieter with the Amsoil 0w-20 SS. I was running good oil before, however this one seems even better.

The absolute best oil I have ever used.

Best oil I've ever used

In my truck

My Engine has never ran so smooth! Engine temperature runs slightly cooler as well. I couldn't believe it till I seen it! Want a vehicle to last longer just treat the engine with this oil.

I use amsoil for all my oil changes to have the best for my hemi/Ram

I researched all the oils and for several years Amsoil is the only oil I use in my personal vechicals and my customer's motorcycles.

Best in class product!

I LIKE THE WAY AMSOIL PRESERVES MY EQUIPMENT. IT ALSO MAKES THINGS RUN SMOOTH AND POWERFUL THE ROLLERS ON MY OVERHEAD GARAGE DOOR RUN SMOOTH AND EASY WITH THE AMSOIL !0-30 SIGNATURE SERIES OIL!

Ask any knowlegable mechanic, they all praise this product.

This I used it my John Deere. I put it in the automatic transaxle. Much quieter now, and faster.
