A 4hp Johnson outboard motor typically uses a mixture of gasoline and 2-cycle oil, usually in a ratio of 50:1 or 100:1, depending on the specific model and year. It's important to consult the owner's manual for the exact fuel-oil ratio recommended for your particular motor. Using the correct mixture helps ensure optimal performance and longevity of the engine. Always use fresh, unleaded gasoline to avoid potential issues.
