Most Liked Negative Review
Terrible product
Upon acceleration my car would kick nd buck through the gears and then even out. I was told to put this in my car which I did. The problem became worse such that as I was driving out of my neighborhood the engine went dead and could not start. Had to call a tow and wait 2 hours and now I would have to tow to mechanic. This stuff is junk it will ruin you car don't chance it like I did.

Prior to using this, my car was averaging around 26-28 MPG on the highway (using mid-grade gasoline). After using this, my car was averaging over 30 MPG. I've used others before, but never had results like this! Well worth the extra money!
