* Different Additives: New and old engine oils may have different additive packages designed for specific purposes. Mixing them can dilute or alter the intended formulations, compromising the oil's overall performance.
* Viscosity Changes: New engine oil typically has optimal viscosity properties that contribute to proper engine lubrication. Adding new oil to old oil can change the overall viscosity of the mixture, which may not be suitable for your bike's engine specifications.
* Contamination: Old engine oil accumulates contaminants like metal particles, dirt, and combustion byproducts. Adding new oil without draining the old oil allows these contaminants to remain in the system, which can cause wear and tear on engine components.
* Reduced Lubrication:Mixing old and new oils may compromise the overall lubricating properties of the mixture. This can lead to insufficient lubrication between moving parts in the engine, resulting in increased friction, heat buildup, and potential engine damage.
It is always recommended to follow the maintenance guidelines specified in your bike's owner's manual, which include recommendations for proper oil change intervals and the type of engine oil to use. Regular oil changes ensure optimal engine performance, reliability, and longevity.
