Yes, you can use regular gasoline in a Coleman stove, but it's not recommended. Coleman stoves are designed to run on white gas (also known as Coleman fuel) or, in some cases, on propane or butane. White gas is a specific type of fuel that burns cleaner and produces less soot than regular gasoline, which is designed for use in cars.
Using regular gasoline in a Coleman stove can be dangerous and lead to performance issues. Gasoline contains a higher level of impurities compared to white gas, and it can create more soot and emit toxic fumes when burned in a stove not designed for it. Additionally, the stove's performance may be inconsistent, and there could be a higher risk of fuel leakage or flare-ups.
For safety and optimal performance, it's always best to use the fuel specified by the manufacturer. If you're uncertain about what type of fuel to use for your Coleman stove, refer to the stove's manual or contact Coleman directly for guidance.
