The Fuel Economy thread

[The Monty]

I see a lot of figures being thrown around here when people get asked about fuel economy, so thought I might start a thread up to show how to work out and properly record fuel economy. I will also add a template for people to follow.

Combo (engine type, gearbox):
KM driven (how many Km you drove before you added fuel to the car):
L to fill (how many L the car took to fill):
Price per L (just for giggles):
Location (temp and conditions have an effect on fuel consumption):
Fuel type (also have an effect on consumption):
Average KM (if you have a Fairmont or climate control):
L/100km conversion (L divided by KM x 100):
Average L/100km (if you record here every week, you can work out your average):
Things to keep in mind.
Reset trip meter when filling up.
If you have diff gears, work out all your conversions before posting up figures that arent correct.
Try and use the same bowser and filling technique each time.
Dont count the DTE figure when posting up your figures, use only the trip meter count, as DTE will only give you an estimate on how much you MIGHT get from the rest of the tank if you keep driving the exact same way your driving at that time.

Ill go first, then post up the copy and pasteable table for people to use.
