Small correction for you, too, Marcus. It's either "liters per 100 kilometers" or "L/100 km". Per is not used with symbols and the solidus isn't used with full unit names.
I wouldn't expect the average person (i.e., someone we're trying to persuade to use metric) to know that and wouldn't worry if s/he didn't conform perfectly to that standard, but those of us who are regulars on this list know better, don't we? <g> Now, daL/Mm -- that's really elegant (and would be more so if the next CGPM meeting would change the prefix da to D, for DL/Mm). It won't fly with most people, unfortunately. L/100 km and km/L are too entrenched.
