OK firstly let me concede distance of 440 km is wrong 390 km has been the best from a
tank. BUT the other figures are absolutely correct, but maybe confusing in its translation. Put simply… if it can be.
I traveled 484 km on 7th January 2004. I fueled 3 times.
On the first stop (at 108km) I used $6.25 of gas. The price of unleaded was 81.9 cents per litre. Gas was 38.5 cpl. If I had used that $6.25 to buy ulp it would have given me 7.63 litres which equates to 1.677199479 gallons. 108km which is 67.08075
miles divided by 1.677199479 gallons is 39.99569 mpg.
On the second stop (after another 223km), I filled up and used $11.51 of gas. Gas was 35.9 cpl. The price of ulp at this stop was 85.5 cents per litre. If I had used that $11.51 to buy ulp it would have given me 13.46199 litres which equates to 2.958678748 gallons. 223km which is 138.5093
miles divided by 2.958678748 gallons is 46.81458 mpg.
On the 3rd stop (after another 153km), I filled up and used $9.81 of gas. Gas was 37.5 cpl. The price of ulp at this stop was again 85.5 cents per litre. If I had used that $9.81 to buy ulp it would have given me 11.47368 litres which equates to 2.521688837 gallons. 153 km which is 95.03106
miles divided by 2.521688837 gallons is 37.68548 mpg.
The first leg was a little town and mainly highway. The second leg was all highway. The third leg was highway and then some driving at the
Gold Coast. All driving was at the speed limit. Four people were on board and their luggage. In all it cost me $27.57 to cover 484 km. On this trip the price of LPG was slightly less than half of ulp.
Now to the present day. I filled my car last Saturday with all town driving. It cost me $35.22 to fill. If I had bought ulp with that money I would have received 28.657 litres which is 6.298 gallons. I covered 298 kilometres which is 185.093
miles. This equates to 29.389
miles per gallon for ALL TOWN DRIVING…. And no I don’t use angel gear or hook onto the back of buses. Why do you think a large number of taxis run on lpg.
Because of the difference in price of the 2 fuels and also the expected consumption rates, I find it more relevent to use this method to compare.
This is why I will be changing my other vehicle to gas as
well. I have compared my fuel consumption figures with a friend at work who has the same vehicle (year and model) and my fuel costs are just over 50% of his which is petrol only (over a long term basis). The savings are there to be had at the moment especially with a $2000 rebate from the government. Excise rates are to be increased from 2011 starting at 2.5 cents per litre and increasing to 12.5 cents per litre in 2015, so this will have a real impact on the feasibility of changing over. Untill then I will be filling my 4wd drive at the lpg bowser and smiling at the dollars I am saving. Just remember the cheaper lpg is in relation to petrol the better for the wallet.
Sorry for the longwinded reply but this had to be done to backup my reasoning for loving lpg. LPG is definitely worth investigation, but of course with the other factors listed above taken into account ie vehicle condition and suitability etc.

You say "If I had used that $9.81 to buy ....... but you DIDN'T and you wouldn't have got that far so it is nothing but positive spin. I think you must be a politician! Your actual fuel consumption ranges from 14 to 22mpg - actually less than that now that you've changed to mileage figure.

Kc, I think what you're trying to say would better be described as dollars/kilometer. I run a V8 Statesman on gas and understand perfectly what you're trying to say.
My Statesman gets roughly the same fuel economy as your Jack, but goes a whole heap quicker ;-)
I pay approx $30 for 60Lt of gas which takes me about 320Ks. Thats about 18.75lt/100ks at a cost of $9.37/100Ks. To travel the same distance for the same dollars on petrol I would have to achieve 7.5Lt/100Ks. Best I can actually get is about 14Lt/100Ks ;-~
So what your saying is the cost "equates" to running on petrol @ 45mpg (in your example)
As far as the excise increase is concerned, just remember that over the same time frame the price of petrol will increase considerably. Gas will obviously go up too, but not to the same extent, so the difference in price will probably be the same, if not better in gas's favour.
Got to get the Paj done ASAP.

Hi John
Thank God someone understands the point I am trying to make. It is easy to compare diesel and petrol because their cost is roughly the same. It is a lot harder with lpg because of the large difference in price and also usage rate. That is why I used the "if i had bought petrol' scenario to explain the savings possible. I thought this would simplify things but obviously not. I feel that comparing fuel consumption rates between the 2 fuels does not give a true indication of the savings because of 1. the fluctuation in price differences between the two, and 2. the difference in efficiency of the fuels. I have seen the price of lpg vary between just below 50% of the price of ulp to roughly 70% of the ulp price locally. Unfortunately locally we pay up to 10 cents per litre more than capital city price. I could have used the cents per kilometre measurement as
well but that changes with the ever increasing rise in fuel prices so cannot be used over a long term....repeat long term.... to reflect the savings unless c/km rates are also kept for petrol. By using the "if it were petrol" equation, the figures are relevent whether they were yesterday or ten years ago. If you can explain this another way so that Aandy understands please jump in as I don't know how I can make it any clearer.
Your comments about the excise versus petrol costs in the future is spot on. I am sure we are on the right track running lpg.
