Using a different viscosity oil than what is recommended by the manufacturer can have some effects on the performance and operation of your engine. Here's what may happen if you use 20W50 oil instead of 10W30 oil in your Honda Aviator:
Thicker Oil Film: The viscosity of the oil affects how effectively it flows through the engine and lubricates the moving parts. 20W50 oil is thicker than 10W30 oil, which means it forms a thicker oil film on the engine components. While this can provide better protection at high temperatures or in older engines with higher clearances, it can also result in reduced flow and potential strain on the engine during cold starts or in colder weather conditions.
Increased Friction: Thicker oil can result in increased friction within the engine, potentially leading to reduced fuel efficiency and slightly decreased engine performance. It may also generate more heat within the engine, affecting overall engine efficiency and longevity.
Oil Pump Strain: The oil pump, designed to circulate a specific viscosity of oil, may experience additional strain when trying to pump thicker oil. This can lead to reduced oil flow and potentially impact the overall lubrication and cooling of the engine.
Warranty Considerations: Deviating from the manufacturer's recommended oil viscosity may also impact warranty coverage, as using a different oil specification than recommended can void certain aspects of the warranty.
It's important to note that the specific effects of using a different oil viscosity can vary depending on various factors, including climate, engine condition, and the particular motorcycle model. It's generally recommended to adhere to the manufacturer's oil viscosity recommendations for optimal engine performance, longevity, and warranty compliance.
If you have already used 20W50 oil in your Honda Aviator and are concerned about the potential consequences, it is advisable to consult a professional mechanic or authorized service center. They will be able to assess the situation, provide accurate guidance, and, if necessary, perform an oil change to ensure the proper functioning of your motorcycle.
