Here's why:
* Increased Oil Consumption: Running with excessive oil will lead to a richer fuel-oil mixture. This means there will be less fuel available for combustion, resulting in reduced power output.
* Fouling & Build-up: The excess oil will cause more carbon build-up on spark plugs, combustion chamber walls, and other internal engine components. This fouling can hinder combustion efficiency, further reducing power and leading to potential engine damage.
* Smoke & Pollution: Excessive oil will lead to increased smoke from the exhaust, signifying a poorly running engine and contributing to environmental pollution.
* Engine Wear & Tear: While the oil does act as a lubricant, too much oil can actually contribute to increased wear. The excess oil can wash away vital lubrication in critical areas, causing premature wear and tear.
The Bottom Line:
Two-stroke engines are designed to run with a specific fuel-oil mixture ratio. Using too much oil can seriously harm your engine. Always follow the manufacturer's recommended fuel-oil ratio for your specific engine.
