Can someone check my figures?
NOTE, everyone may have their own opinion on the figures i have used but it is a starting point
Fuel cost as of today at the local petrol stations in melb and canberra
Petrol $1.40/ $1.31
LPG $0.50/$0.64
Diesel $1.20/$1.31
Travelling canberra - melb - canberra is 1,300 kms per fortnight plus running around so say 750klms per week = 39,000klms per year
Car stated average litres per 100klms for petrol and diesel is 10.5/8.2 - driving style would change this but unknown
Conversion cost of LPG is $4,500 and diesel option is extra $3,250 - could negotiate on tese prices
Litres used petrol or LPG is 4,095 and diesel is 3,198 per year at 39,000klms
Fuel cost per year of melbourne and canberra is
Petrol $5,733/$5,364
LPG $2,047/2,621
Diesel $3,838/$4,189
This would give a payback period of LPG over diesel of only 1 year and a saving of around $1,500 on fuel with LPG over diesel for each year after that at 39,000klms per year or $375 per year at 10,000klms plus cheaper servicing cost
Seems to me if the above figures are even somewhat correct, going LPG is a no brainer in the financial sense
