How much do you spend on gas for the car getting to the trailhead?
Interesting question. Now, you've made me curious, so let's do the math.
For this past weekend's trip, I drove 180 miles round trip. My car gets about 28 miles per gallon of gasoline. I therefore used roughly 5.7 gallons of gasoline on my drive. Gasoline costs $3.84 per gallon. I therefore spent $21.89 on gasoline.
I melted snow and cooked hot meals. I used one 110g canister of Snow Peak isobutane-propane. There's a bit left in the canister (10g – 15g), but for the sake of argument, let's say I used an entire canister. I certainly had to buy a whole canister. A 110g canister costs $4.99 plus 9.75% tax or $5.48.
With isobutane-propane gas, my total fuel cost for the weekend was therefore $27.37 of which 20% was cooking fuel cost.
If I had used the equivalent amount of white gasoline (about 8 fluid ounces assuming an isobutane-propane canister if filled at the factory to its full liquid capacity), my cost would be $0.61 (128 fluid ounces of Coleman fuel is $8.88 and there is a 9.75% tax).
With white gasoline, my total fuel cost for the weekend would have been $22.58 of which 3% would be cooking fuel cost, and I would save $4.79 for that trip.
Probably not earth shattering numbers, but you got me curious. For those who take more frequent trips or who do a lot of cooking, perhaps fuel cost is salient.
Of course, white gasoline usage would probably be a bit higher than gas. My own experience indicates about a 5 to 10% increase due to the necessity of priming and also the little bit of fuel that is wasted in the fuel line on disconnection. I know others have posted about a 30% increase in white gasoline usage over gas. Obviously cooking style will affect one's numbers greatly.
