REV X High Performance Oil Additive - 4 fl. oz. (1 Pack)

Works great

Great product. Super fast shipping

I have a 2003 Duramax 6.6. I just recently did an oil change 12 quarts and I put one of these in a day after I did the oil change and noticed a big difference in my turbo and power.!! I was so impressed. I ordered a second bottle and just put it in today.!! This will be my new routine while changing oil two bottles treats 8 quarts good enough for me. Recommended would be three bottles for 12 quarts but even after one I noticed the huge improvement My Truck is fast.!!

Delivery was on time. The product is super easy to use. I give it a rating of three stars because I see zero improvement any of the advertised areas, "engine noise, power, milage, ease of starting". I also didnt see that it hurt my engine. Would I buy it again? Definitely not

I got this RevX stuff about two weeks ago and did an oil change the next day. Ran it in for more than three heat cycles. Honestly did not see any kind of difference in engine performance, noises, gas mileage or a drop in oil temperature? This is pretty much snake oil at best. I personally don’t recommend Rev X.
