This material is motor kryptonite. Use regularly at every 3rd or 4th oil change. Pour a third of a bottle into the engine like I did, then the rest of your favorite motor oil and you're done. Take your "baby" for a ride and get ready for a 4-7 horsepower boost in W'room Va'room! If I win the lottery, I'll buy the company! A bit overpriced but worth every penny! How it works? No idea! Really fantastic science in this product!
