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.
