According to Crews and Equipment, how often should the chainsaw fuel be swapped out?

• A. Every 6 months
• B. Every 3 months
• C. Every 2 weeks
• D. Every 4 weeks

Answer: (C)

Regular fuel freshness is the key idea. Gasoline sitting in a chainsaw degrades over time and can absorb moisture, especially with ethanol blends, leading to gum, varnish, and corrosion in the carburetor and fuel system. Swapping out the fuel every two weeks keeps it fresh and reduces the chance of starting problems, hard running, or power loss that come from degraded fuel. This interval strikes a practical balance: longer gaps invite more degradation, while much shorter ones isn’t usually necessary for typical use. Using fresh fuel or stabilizer helps, but the two‑week practice is the recommendation to keep the engine reliable in regular operation.
