Didn't GMI poster Dr Terry record about 9 L/100 km when running on LPG during a touring holiday (four-up & with luggage) in a Holden VE Omega V6 equipped with optional dual-fuel?
At the currently typical fuel prices as illustrated above, this translates into a fantastic cost-equivalent of under 4 L/100 km (delivered in real-life conditions AND from a large & reasonably powerful 6cyl automatic sedan!) or over 70 I-mpg in the old money
Which AFAIK is cheaper in actual fuel-cost-per-distance than might be comparably achievable by
any petrol or diesel passenger vehicle sold in Australia today - including micro cars with micro room & micro performance
As an aside it always strikes me as odd that virtually every media judgement of LPG centres purely around the
initial 'payback period' .. yet typically avoids any mention of future & ongoing fuel savings or economy
