Well, it happened! My wife drove our VW Beetle TDI with the GreaseCar system by herself this evening and succeeded in driving the car halway across town in PURGE mode. Needless to say, she ran half the diesel tank into the WVO tank... Fortunately it only overflowed a *little* bit...

I think this is enough reason to *NEVER* let her drive my Benz, certainly not by herself - only with me in the passenger seat!!!
