For the last couple weeks or so I've been doing the coasting down hills w/ the engine off then popping the clutch in gear to restart the engine and getting back up to speed. Today on my way to work I was feeling something wierd, I think the clutch is slipping. Has my attempt @ increased fuel mileage hastened my need of a new clutch? Maybe this technique is not saving me any money after all! Car is a '95 Ford Aspire... last mileage w/ the P&G is 49.
I can't answer that, but until you are sure of what's going on, you might want to stop bump starting -- either use the starter, or don't EOC. I'm experimenting with P&G sans EOC and it's definitely worthwhile.
