....I have a few Coleman items that run on Coleman fuel (naptha gas) and they're pretty darn reliabe in all weather. If taken care of there's no need to worry, I've seen Coleman laterns and stoves older than I that still perform wonderfully. Depending on age it may need a few replacement parts readily available at most CTC stores. Have to admit though niether I nor anyone I no has tried using unleaded fuel, no need to really with the availability of naptha fuel.
