Here's why:
* No separate lubrication system: Unlike four-stroke engines, two-strokes don't have a dedicated oil sump and pump. Instead, the oil is mixed directly with the fuel to lubricate the moving parts.
* Oil injection: Some newer two-strokes use oil injection systems, which automatically add oil to the fuel based on engine load and speed. However, many older or smaller two-strokes still require pre-mixing the fuel and oil.
The correct oil-to-fuel ratio is crucial and varies depending on the engine model. Consult your owner's manual for the recommended ratio for your specific two-stroke engine. Using the wrong ratio can lead to engine damage or premature wear.
