ZmOz said:Not in the U.S. Propane is about $1.85 here, while gas is about $2. Given the fact that you need more propane to go the same distance as gas, it will actually cost quite a bit more per mile.
$2/gallon? Sign me up for that: in L.A. we're being hit for around $2.30/gallon for 87 where I am (though I have seen it as low as $2.15/gallon - prices do seem to be slowly coming down). Diesel's down around $1.90-$1.95, so there's a pretty decent difference between the two.
Also, as an aside for anyone who doesn't know about it yet: www.gaspricewatch.com - locate the cheapest stations in your area.
