I bought the van in Sept 04 with 228,000 kms on it & it worked great. It now has 237,000 kms on it & about 1 month ago it started to tap when it was started cold, sounded like a bad lifter to me. I heard about your product from a friend so thought I'd give it a try. We did an oil change & put in the stabilizer, after 2 days the noise was gone, the vehicle now runs cooler ( it always ran a bit warm for my liking) & I even notice an increase in gas milage. Imagine all this simple after 1 use, I'm sold & am now a user for life.
