Since when is a “Hundred Kilometer” a unit of measure?
If they want to talk liters per kilometer, well, that makes sense. Or maybe milliliters per kilometer, if they want to deal with intergers.
Thirty MPG would be 12.75 km/liter or 78 milliliters per kilometer.
If you are going to a consumption measure, I like ml/km.
The very worst cars would consume about 250 ml/km, where as the best would consume about 50 ml/km. That gives you a 200 unit range, which is good for discriminating numbers. You don’t have to deal with a lot of fractions to get good resolution over 200 units.
The diffrerence is in measuring consumption as opposed to milage.
MPG is a “positive” figure. The bigger it is, the better off you are. This fits well with a generally positive and optimistic outlook on life, so it is favored by Americans.
Liters per 100 kilometers is a “negative” figure. The higher it is, the worse off you are. It fits well with a mind-set that consumption is bad, and that life should be about lowering consumption rather than maximizing wealth. That is why this measure is favored by Europeans and enviro-weenies of all stripes.
I guess hectokilometer could be used.

Using ounces and feet is sometimes interesting.
30 mpg would be about 0.234 miles/ounce or 1,237.5 feet/ounce, or 4.267 ounces/mile.
16 mpg would be about 0.125 miles/ounce or 660 feet/ounce, or 8 ounces/mile.
An ounce of fuel for just 660 feet really doesn't sound that impressive.
