Actually, my benchmark is the Price/km column. Below 0,10 is okay (even if it hurts). The maths is quickly done: Price * 10 < Trip?

I didn't follow the consumption / economy discussion - never saw it discussed to be honest. As long as I remember it was fuel consumption (super trump card games - anyone?). As in the US two different units are used (miles and gallons), my math never crossed the Atlantic.
