Given that, I'd have to pick Woolite. It might suck at cleaning the garage floor, the dishes, the car, and most everything else but at least my wife wouldn't cut parts of me off for ruining the sweater.
I think I get the basic idea, though, and I agree that M1 TDT is a pretty solid all-around pick. But back to the detergent example... I've got 3 engines that really don't want Xw40 oil. Of those, 2 are flat-tappet muscle car engines, and one is a modern roller-cammed economy car engine. One size just doesn't fit all, so I use RTS, RP 5w30, and M1 5w30AFE in my lil' fleet at the moment.
The best detergent is Gain,hands down
