My customers are saying NONE! I don't argue with them because my experience is with propane. I know your discussion addresses how much to carry on the trail. My interest is in the customers shifting from Coleman Fuel to unleaded gas when heading out on the trip.

I used to sell hundreds of cans of Coleman Fuel. Now I sell < five cans per year. When asked about using unleaded in their stoves, I can get none to admit that they have had any problems with their stoves. I have read all of Colemans warnings (Marketing ?) and the other fuel manufacturers.

What is your take?

I am thinking of cacheing fuel on my Creature-of-Habit trails.
