It’s Important to Get the 2-Stroke Fuel-Oil Mix Correct in your Outboard.
Engine Longevity: A correct oil mix ensures that your engine is properly lubricated. Too little oil can lead to increased friction, causing severe engine damage or even seizure. Too much oil can lead to excessive smoke, carbon buildup, and poor engine performance.
Performance: Using the right fuel-to-oil ratio ensures optimal performance. Incorrect ratios can cause your engine to run poorly, leading to reduced power, inconsistent operation, and hard starting.
By maintaining the correct mix, you avoid expensive repairs due to engine damage and help keep your 2-stroke engine running smoothly for longer.
