Customer Ratings & Reviews

I've been using the product for many years and trust Amsoil for all of my equipment - car, truck and all power equipment.

... in every vehicle I have owned, new or used, and will continue using Amsoil as long as I have a car! Never had a problem even though I changed the oil annually. One service tech even asked why I was changing the oil since it was so clean! That's Amsoil, that's quality!

As always, Amsoil produces great products for our "fleet' of vehicles ranging from SUVs, motorcycles, and trucks. Customer service is unparalleled.

I have used Amsoil in all my equipment for many years. I still enjoy changing my own oil and maintaining all routine maintenance myself. I appreciate being able to to go an entire year without another oil change and doing the work myself. I use this oil in my street rod, full size suv, 4 stroke outboard boat and gearbox, plus all of my outdoor lawn equipment. I also use Amsoil 2 stroke oil in all of my lawn equipment including a 1976 Homelite chain saw that has never been overhauled that still runs very strong.

AMSOIL 0w-20 Signature fully Synthetic Motor Oil. Been using this oil in my vehicle since I purchased it.

I received fast shipping on a great product! Thanks Amsoil!

My vehicles run smoother, with less vibration, and are quieter. The also run about 10 degrees cooler than they do with other oils. And, my gas mileage went up about 3 miles per gallon.

I have used Amsoil Signature oil in my business car. Today with over 400,000 miles on it.... Still running like new! No other oil even comes close to the protection and value of Amsoil Signature!

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
