Rx270 engine oil starts abnormally.

What you want to ask is what caused the abnormal starting noise of rx270 oil? The reasons are lubrication system problems and piston ring problems.

1. Lubrication system problem: Burning engine oil will affect the lubrication system of the engine, leading to wear and excessive wear of the friction parts, and then generating abnormal noise.

2. Piston ring problem: If the piston ring is damaged or worn, it will cause oil to enter the combustion chamber, causing the engine to burn oil. In this case, abnormal noise will appear after the engine is started.
