on long trips or touring it’s wise to work out fuel consumption, liters required for the trip and the cost of fuel to work out a travel budget.
If the trip involves a lot of soft sand tracks the fuel usage will be far more
than other terrains.
A vehicle with 13 liters to 100 km on the highway could
use up to 22 liters per 100 km in sand just to give you an idea of the
difference in terrain fuel usage!
the trip you are planning takes you into the outback or far north then getting
an idea on the petrol/diesel price per liter is a must as it can be 50 c or even
more expensive per liter. Outback fuel is not cheap!
Fuel Quality And Bad Fuel:
quality really varies from fuel stations, I will not give up names but there
are a few I would never ever use as I just DO NOT trust their diesel/petrol and
these are right here in Perth.
The same goes for in the bush and small town fuel stops, most are good but
Filling up during or just after a fuel tanker has been and emptied is not the
best idea as the refilling action causes the settlement on the bottom to stir
up mixing with the new fuel. You can't know when one has just been but if you
see one there unloading take caution!
Premium fuels versus regular and cheaper fuels:
I also recommend using the premium fuels versus cheaper fuels, it’s better for
the engine and will give you more kilometers for your hard earned $$'s. doing it
just once for the first time won't make any difference, it needs to be used for
about 5 full tanks before you will notice a real difference.
Fuel Calculation Formula’s:
Formula for liters per 100 km:
Liters used * 100 divided by kilometers travelled = answer per 100 km
Example: 107 liters * 100 = 10700 / by 790 km = 13.54l per 100 km
Formula for kilometers per liter:
Use the kilometers travelled divided by liters used.
Example: 790 kilometers travelled divided by 107 liters = 7.38km per liter
Liters required for travel formula:
To estimate the liters required for a trip:
2000 km trip divided by 100 = 20.00
20.00 * 13.54 (the above liters per 100 km) = 270.80 liters required.
Keep in mind different terrain will use more fuel; this is based on high way
driving fuel consumption.
