I thought it may be a good idea to start a thread on fuel consumption so that we might all gauge our fuel usage based on an average.
We will keep the posts simple and to a formula.

Engine type:
Engine Size:
Tank Size:
Kilometers to tank:
L/100km:
Carburettor type / or injector size:

Would L/100 be a more common measurement value?

Or are we all too smart to calculate that one.

Hmm, might be difficult to measure - I'm only on my second tank of fuel this year...
Then there's that pesky breather hose that seems to leak 10 litres every time I fill up!

Back when I used the car as a daily driver I was getting about 450Km from a tank, about 13.3l/100km.
Country trips were much better, hooning about much worse...

Engine type: L
Engine Size:2.8
Tank Size:60
Kilometers to tank: 450
Kilometers per litre: 7.5
Carburettor type / or injector size: round tops

Yes, that would be a much better measurement. Let's change that to L/100km
