What Happens If You Overfill Engine Oil?

[Ken]

Overfilling engine oil can have the following effects: 1. It creates significant resistance to the high-speed rotating crankshaft, reducing power output and increasing fuel consumption during vehicle operation. 2. It increases the amount of lubricating oil splashed onto the cylinder walls by the rotating crankshaft and connecting rods. 3. It raises the rotational resistance of the crankshaft, decreases engine output power, leads to oil burning (blue smoke emission), increases fuel consumption, accelerates wear of cylinders and piston rods, and shortens the vehicle's service life. Here's relevant information: 1. Engine oil should be filled between the marks on the dipstick, preferably below the upper limit. During driving, oil may leak due to vehicle vibration, so avoid overfilling. 2. When selecting engine oil, consider factors such as vehicle model, season, climate, engine displacement, and technical performance. Choosing the right engine oil provides better working conditions for the vehicle and prevents oil-related malfunctions.
