LPG, VSI system. So I lose a little off the top end. Big Deal. Atm fuel costs costs are less than half what they would be if I was running petrol.
Here's my sums:
Average LPG refuel price/litre, c/L: 47.9
Gross up by 15% for the extra gas I burn over petrol = 55.09
(I've checked this heaps of times, difference is always about 15%)
Average petrol price/L atm: $1.20
0.55/1.20 = 45.8%
In my case it means I save about $75 per week, or $3,900 per year. Even if you knock a couple of hundred a year off that for the extra plugs and leads I go through, I'm still well ahead.
Laughin.
