It seems many modern cars have been plagued by headgasket failures in the 150,000 mile range. Not worn out, not burning oil, ****** great, but otherwise useable car becomes a throwaway because of that expense. Something like that CRC product shows there is incentive to create a cure and as stated technology just might solve it. (For us too). I would still drain, flush, repeat.
