Fuel economy and maths

An example: If you used 46 lt to travel 553 km.
Divide 46 by 5.53 (the number of 100 km stages) giving 8.3 lt per 100 km

Calculators help.

Morning jon p, if u go to the Caravan & Camping site u will be able to down load a Fuel consumption chart. This chart has a conversion of ltrs per hundred klm makes life easy.

This fuel consumption calculator may be useful too:

Jon,

One of many calculators you can find.

As to calculating it manually, for an example, if you have travelled 425 km and used 73 litres - divide your km by 100 (425 km divided by 100 = 4.25) Then divide your litres used (73) by 4.25 and your answer is 14.6 l/100km. The simple way is to use the calculator in the link !

The other way is to divide your Km travelled, 650, by the litres used, 54, which gives you 12 km/lt.
I find this much easier when doing a trip, set trip meter once full, then divide the km on the trip meter by the litres you put in the car when you fill up, this way it's easy to work out how many km you can travel with the amont of fuel you have with you. ie. to travel 650 km you divide 650 by 12 = 54lt, so if you need to travel 650 k's between fuel stops you know you will need 54 ltrs plus a safety margin to do it.

I have the simplest system of all. I dont look, therefore I dont see, therefore I dont know.
That way I can still travel with my petrol 80 series happily towing my trailer.
When asked what the trip cost I say,I enjoyed it.

Some people like to work in litres per100 kilometer and others kilometers per litre. To switch between the two divide either into 100. eg 12 litres per 100k, divide 12 into 100. Answer = 8.33 (recurring ) kilometers per litre. 8.3333 etc into 100 = 12 litres per 100 kilometers.

I hope this covers all scenarios that you need.
