Is it normal for the dipstick to smell like gasoline when pulled out?
1 Answers
The dipstick smelling like gasoline when pulled out is normal. The function of the dipstick is to measure the static liquid level height of the engine oil, thereby reflecting whether the engine oil level is within the normal range. The reasons for the dipstick smelling like gasoline are as follows: 1. The engine has been used continuously for too long: The clearance between the piston and the cylinder wall becomes larger. Since the pressure in the combustion chamber is always greater than that in the crankcase, a small amount of mixed gas enters the crankcase. 2. The lubricating oil has not been changed for a long time: This causes the oil film thickness to decrease, resulting in insufficient piston lubrication. The cylinder wall may be scratched, leading to blow-by gas. Under various conditions, the ability of engine oil to reduce friction, slow down wear, and prevent metal sintering is called the lubricity of the engine.
