Precautions on Oil Change
◆ Excessive and insufficient oil amount can both affect engine performance.
Excessive Oil－Increased friction resistance of moving parts in the engine, which
lowers output power and increases engine temperature, leading to early
deterioration of engine oil.
Insufficient Oil－Reduced oil supply to moving parts in the engine, therefore
results in worn parts, parts ablation, etc.
◆ Do not mix-use oils of different brand, class or low quality ones; they may
cause engine faults.
◆ Kymco Emissary Engine Oil contains additives (e.g., spirits, etc.) during the
manufacturing process.
◆ Arbitrarily mixing additives bought from the market may deteriorate the oil,
affect lubricating properties and shorten the service life of engine.
