    I'm getting around 300Km with a 59L manifold tank. Works out about 19L/100Km on a 4.6 ZF auto RRc. And that includes the Mount Ousley Road in both directions with travel at 100 - 110 Kph.

    Mine always runs out of fuel going up hills.

    (I could turn it back to use up the dregs going down the next hill, but that can't be good starving the engine too often.)

    You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.

    I thought LPG shouldn't be effected by any angle.

    Is your system running correctly?

    Is that 72 useable litres or is it a 72 litre tank minus 20% for expansion , which makes about 58 useable litres for 250 k

    I'm no expert on these matters, but the LPG comes out of the tank as a liquid and is converted to a gas at the "converter" in the engine bay. There is always an air space in the cylinder to allow for expansion (the reason the 84Lt volume of the tank can only hold 59L LPG). So I would assume that there has to be a liquid pickup inside the tank, in my case it is the three separate interconnected cylinders and I am assuming when the the tanks are near empty and I'm going up hill, the remaining liquid flows into the rear cylinder while the pick-up is somewhere forward and hence no go. There have been occasions when I have switched back to LPG and get another 10 or more Km on the remains.

    Someone else may be able to inform us if my theory is correct and more importantly if my system is working correctly?

    to get to 13L/100kms more than that would have to come off!

    Fuel equalisation, LPG in theory should be able to run on any angle, that and the price of the gas are the main advantages of such a system.

    As for economy, on my trip to Bowtells bridge on Wednesday, with Lokka as a witness I put 33L of diesel in my 4BD1 County on Tuesday arvo, the fuel light was just starting to illuminate so say at most 9l left in the tank before the fuel up. Aggressive mud tyres, full roof rack, 8 people 2 esky's and all the crap the kids need for a cold day out. My low stress engine only got 10.39l/110kms, I would love to see a V8 get 13l/100km's but cannot see how.
