Engine pinging and knocking?

5 star customer reviews
"Definitely was worthy of purchase. Made a big difference in my car's idle. Will be purchasing more of this for other vehicles that I own."
"Fuel gauge in my SUV stopped working. Followed the directions and dumped it into a fresh tank of gas when I filled up. After about a week the fuel gauge started working again. Seems to do what it claims. Thanks!!"
"I was quite pessimistic that this product would work, however after using it in a tankful of gas in my motorcycle, I must admit the engine runs smoother. I will now buy additional bottles for all my vehicles. Good stuff!"
