Which statement about fuel and bar oil usage in the saws is correct?

• A. False
• B. True
• C. Not specified
• D. Depends on model

Answer: (B)

Using the right fuel and bar oil is essential for a chainsaw’s performance and safety. This is true because a two-stroke engine relies on the fuel-oil mix for lubrication, so the correct mix ratio protects the engine from wear and overheating, while the correct bar oil keeps the chain and bar properly lubricated to prevent excessive friction and heat. Running with the wrong fuel, stale or improper oil, or the wrong bar oil type can lead to poor starting, reduced power, increased wear, fuel-system problems, and potential engine damage. In practice, each model has its own exact recommendations for fuel type, mix ratio, oil grade, and oil capacity, so always follow the manufacturer’s specifications. The principle that proper fuel and bar oil usage is necessary is true across saws, which is why this statement is considered correct.
