Customer Ratings & Reviews

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.

I use it in everything I own

I can't say anything bad about this oil. Our 2016 Mazda 6 has had zero issues from the drivetrain. Zero issues with anything actually. I changed the engine oil and trans oil(manual) out as soon as I got the car home with less than 50 miles on it. The only thing I do that's not amsoil is add Liqimoly because the factory oil for our engine requires a high moly content. I change the oil every 15-20k and top off every 3-5k. The engine looks very clean inside the crankcase and under the valve cover. It still runs as smooth as the day we bought it and no leaks at 130K. I also use this oil in my brand new Tacoma TRD off road 4x4. I refused their complimentary free oil changes and stuck with what I know is a higher quality product.

I purchased Amsoil for my 3.6 LFX V6 Camaro. I went about 6k miles and changed the oil in the engine. I sent out a sample to an oil analasys lab and the results came back great. They recommended going 8k miles before changing the oil again because there was still plenty of "life" left. I will continue buying Amsoil.

Great Product , Fast service, good price

I've bought this oil after watching YouTube videos of it beating out the other oils people buy. I usually do royal purple but not anymore. This oil cause less wear and tear and my car runs more smoothly. The best part is it's 100% synthetic. Royal Purple isn't. Great product. Definitely going to buy again.

I have been using Amsoil for 25 years and never had engine issues. Great products!

I have been using Amsoil for over 30 years and think it is the greatest. I use it in all my cars, mower, and mix the marine oil with gas to run in my chain saw, weed,eater, and hedge trimmer. I recommend Amsoil to everyone who will listen.
