Well, yes, of course, there are no free lunches.
Your mileage will suffer, too...
I DO think, and it's only my opinion, that a carefully and sympathetically
maintained engine that's used "hard", e.g. a few track days a year,
brisk acceleration on the street, etc
stands a better chance than Grandma's if she doesn't maintain it.
And agreed, if it has a bad head gasket, don't drive it. The coolant eats the
bearing material, as well as being a substandard lubricant.
But if you accelerated hard and then the headgasket blew, well, it was going to
blow soon anyway.
