Can motorcycle engine oil still be used after more than 4 years?
2 Answers
Motorcycle engine oil cannot be used after more than 4 years and needs to be replaced with new oil. Motorcycle oil change intervals: For new motorcycles, the first oil change is generally around 300 kilometers, the second around 500 kilometers, and the third around 800 kilometers. After the break-in period, oil changes can typically be done every 2,000-3,000 kilometers. Consequences of not changing the oil: If the oil is not changed for a long time, once it deteriorates and loses its performance, it will cause the lubrication properties of the bearings and the lubrication and cooling functions of mechanical transmission components to disappear, thereby damaging the engine, with effects similar to those of oil deficiency.
As a seasoned motorcyclist with over a decade of experience, I must say using the same engine oil for more than four years is absolutely unacceptable. Motorcycle engine oil isn't as durable as car oil—it oxidizes and deteriorates over time, absorbing moisture and dust from the air, significantly reducing its lubricating effectiveness. My own bike once suffered accelerated internal engine component wear due to neglected oil changes, costing me over a thousand yuan in repairs. Motorcycle maintenance is crucial, with typical oil change intervals ranging from six months to a year. Even if you ride infrequently, the oil will still age and thicken, failing to protect critical components. Remember to regularly check the oil's color and viscosity—darkening or thinning are clear warning signs. Changing to fresh oil is simple; spending a little at a professional shop can prevent major issues. Don't gamble with your beloved bike to save a few bucks.
