    Awesome Products

    I have used this product over the past few months and I can see the difference in my Denali pickup and Jeep Rubicon. I use all of the Motorkote products, the hyper lubricant, the fuel optimizer, the octane booster, All Stop, and Power Steering fluid. You guys do an awesome job and my vehicles, and my family's vehicles show the proof. My lifters went out in my Denali this summer and the GM garage told me that the engine looked awesome and actually there wasn't as much damage as they expected. The oil sending senor is what caused the problem, no fault of Motorkote, but the motorkote products protected the rest of the engine. Review by Bostonian • (Posted on 11/7/2015)
