I have an old Gaz backpack lantern (French) which uses the CV470 propane/butane mixture cartridge. I used it in lieu of the Coleman lantern in my Cabela's Guide model tent. I noticed that in really cold weather that it has a tendency to sputter a lot. I guess it is the butane in the propane that is doing it.
