Is it normal for the dipstick to smell like gasoline when pulled out?

[WillowMarie]

The dipstick smelling like gasoline when pulled out is normal. The function of the dipstick is to measure the static oil level height, thereby reflecting whether the engine oil level is within the normal range. The reasons for the dipstick smelling like gasoline are as follows: Excessive continuous use of the engine: The clearance between the piston and the cylinder wall increases. Since the pressure in the combustion chamber is always greater than that in the crankcase, a small amount of mixed gas enters the crankcase. Long-term failure to replace the lubricating oil: This leads to a reduction in the oil film thickness of the lubricating oil, resulting in insufficient piston lubrication. Scratches on the cylinder wall can cause gas blow-by. The ability of engine oil to reduce friction, slow down wear, and prevent metal sintering under various conditions is called the lubricity of the engine.
