Up here in the Great White North, I just paid $1025 Canadian dollars for 205 liter drum of C12. So about $700 US dollars the US equivalent of 55 gallons....so about $12.75 a gallon in your terms. Pretty damn pricey when you start going thru 8 gallons a weekend. Hopefully next years gas may be a tad cheaper with all the downturn in fuel prices...we can only wish...
