Here's why:
* Motorcycle oils are formulated differently. They are designed to handle the higher temperatures and stresses of a motorcycle engine, including the clutch. Regular car oil may not provide the necessary lubrication and protection in these conditions.
* Wet-clutch compatibility: Motorcycle engines often use a wet clutch, meaning it's submerged in the same oil as the engine. Regular car oil can cause the clutch to slip, making it difficult to shift gears.
* Performance: Motorcycle oils are typically thinner and have different additive packages, which can improve engine performance and fuel economy.
What kind of oil should you use?
* Consult your owner's manual: The best resource is the owner's manual for your specific Honda CRF80. It will specify the recommended oil type, viscosity, and API rating.
* Look for JASO MA-approved oil: This certification indicates that the oil meets the requirements for use in wet-clutch motorcycles.
Using the wrong oil can lead to:
* Clutch slippage: Making it difficult to shift gears.
* Engine wear and damage: Due to inadequate lubrication.
* Reduced performance: The engine may not run as smoothly or efficiently.
Always use the recommended oil for your motorcycle engine. It's a small investment that can prevent costly repairs and keep your engine running smoothly for years to come.
