Gas in a chainsaw can stay fresh for about 30 days when mixed with oil, as most chainsaws require a mix of gasoline and two-stroke oil for operation. After this period, the fuel can degrade, leading to starting difficulties and possible engine damage. To extend the life of your chainsaw, it's recommended to use stabilizers in the fuel and to drain the tank if the chainsaw won't be used for an extended period, preventing issues related to stale gas.
