I don't believe there is anything wrong with using a product like Lifetime Peak. But as the old saying goes, "If it sounds too good to be true, it probably is". In this case I would bet that if you had a problem related to the Peak Antifreeze, that trying to get reimbursed for the repair would probably involve taking a trip to small claims court. In other words, it just ain't worth it. That said, I think that this is a good product, but I would not go past 5 years(100K miles) without changing this coolant.
Also, I have heard that GM adds those "stop-leak" tablets in every car with Dex-Cool
