Why?
* Different Lubrication Needs: Engine oil and gear oil are formulated for different purposes. Engine oil is designed to lubricate internal engine components, while gear oil is designed to lubricate and protect gears from wear and tear.
* Viscosity: Engine oil typically has a lower viscosity than gear oil. Gear oil needs a higher viscosity to handle the high loads and pressures within a gearbox.
* Additives: Engine oil contains additives that are not suitable for gearboxes. These additives can cause problems like sludge buildup and premature wear.
Consequences of Using Engine Oil in a Gearbox:
* Excessive Wear: Engine oil won't provide adequate lubrication for the gears, leading to excessive wear and damage.
* Seizure: The gears could seize due to insufficient lubrication.
* Shortened Gearbox Lifespan: The gearbox will fail prematurely due to excessive wear and damage.
Recommended Gear Oil for 2-Stroke Engines:
Use a gear oil specifically designed for 2-stroke engines. These oils are formulated to handle the specific lubrication needs of the gearbox, including:
* High Viscosity: Provides adequate lubrication for the gears.
* Anti-wear Additives: Reduce wear and tear on the gears.
* Extreme Pressure (EP) Additives: Protect the gears from high loads and pressures.
Conclusion:
Using regular engine oil in a 2-stroke gearbox is not recommended and can lead to serious damage. Always use a gear oil specifically designed for 2-stroke engines.
