hi crew, I got a bt50 2008 that gets loaded up once a year and heads off fishing somewhere, because it is loaded to the max it uses fuel,depends who is driving(he who must keep up with the cruisers & gets maybe 14/19lts per 100klms or she who keeps revs at 2000 & gets an impressive 12lts per 100klms), the vehicle only vips around town or does an hour trip here & there, I just did a tip of 381klms & fuelled up with 49ltrs, that's 13ltrs per 100klms empty, with only me & only doin 100klms max, it always used to be approx. 10ltrs per 100klms? been getting ready to do a big trip across the top ,but starting to rethink wot to do, forums tell me others arnt any different ?

Presuming the engine systems are sound.
Since it is 2008 it may require the MAF and MAP sensors to be cleaned with sensor cleaner. CRC make one for the task. MAF is just after the airbox and the MAP, (the one which gets gummed up and filthy) is before the Throttle Body housing above the intake manifold. The MAP senses the intake boost pressure and if claggy it may not indicate true boost to the ECU and the system will be out of whack.
Both are held in with two or three screws and has a wiring connector to each.
If they aren't clean it won't return good economy, normal about 9 to 9.5L/H empty.
Air filter clean?
Bigger tyres? or wider?
Is it auto?
Already weighed down with extras?
Air drag of roof rack?
The faster you try and move more weight the fuel use increases in a logarithmic fashion.
ie, Not much distance for a lot of fuel.
