fuel consumption - subes and other makes

Ran out of fuel for the third time today, tripmeter only said 270! :O
One can drive without a speedo, but not a fuel gauge. I think its worth it to get a new something so my gauge works.

Larger tyre diameter should help with using a little less fuel at cruising speed as there are less rpm required for a given speed than before.

not nessecarily, as the enginge has to spend more effort to keep the wheels turning at a given speed as the overall weight of the drive train has increased.

Took both my units out and gave them a wipe down with metho and cotton thingos... I think it could of worked too!

Car sitting on a flat when i fixed them was reading the dud 3/4s full and when I cleaned them and drove it up on a hill to park it the gauge went to full and as I mucked around on the hill (car facing up hill or car facing down hill) the needle would move a ml or two!

I might throw a DIY clean sender units up sometime.

**** yeah! Those Jensens are sweet as!

The brumby gets me an average of 14L/100km around town, but only cos it spends most of it's time in town on the choke.

A recent 309km trip on the speedo (309 * 7% = 330km) used 32.87 litres of fuel = just under 10L/100km That trip involved the secondaries being open a *lot*

I'd be confident of 8 for a granny style dual carriage way trip

92 GL dual range wagon, 222800km, needs a service, 104km @13.25l (approx from pump), = 7.84km/l with aircon on the whole way @ 110kmh. 1 cylinder down on compression but still just within tolerance. bloody shoody, tune it next week and see what happens.
