    Kreen Experience (piston soak + crankcase + gas)

    I started using MMO when I got this car which was barely drivable a few years ago, based on the stuff I read here. Incredible as it was to me (who didn't really believe in additives), I did my first oil change doing the 1/5 in crankcase formula. It DID change the way this engine behaved in...

    Kreen Experience (piston soak + crankcase + gas)

    eh, can't help but wonder: am I the one being referred to as the "new guy" who "attacks" these products? Hopefully not. I'm merely reporting what has been done and I can't really state whether if this product worked or not, much less judging it. I hope it works, and mostly based on the many...

At higher RPM it isn't audible. Then there's the knocking when accelerating or going uphill. This was fixed...

    Kreen Experience (piston soak + crankcase + gas)

    I didn't have/drive this car for very long. I added 20% MMO for the first two oil changes using Shell Conventional oil, and those oil changes weren't full 3k miles since the car has been sitting a lot. Then I used a full change without MMO using Castrol Edge, which I drove over 4k miles, before...

    Kreen Experience (piston soak + crankcase + gas)

    Just wanted to share my Kreen treatment of my Generation 8 Corolla. This car is known to have plugged oil holes near the piston ring and cause oil burning. After reading threads on this forum, I was hoping that Kreen will dissolve the carbon and restore its health, as some others have noted...
