I have a 1999 Chevrolet 1500 pickup. This truck has 205,000 miles and has not had a single oil leak or tune-up since I bought it new. Needless to say, I have driven the tires off of this truck several times! Your Prolong Engine Treatment and Transmission Treatment are the reason I am still driving this truck everyday. I put Prolong in the engine and the transmission ever since the manufacturer’s warranty ran out. I will take your product over any warranty any day!!!

Thank you, Prolong, for a fine product.
