Can the vehicle continue to be used if the engine oil level increases?

If the engine oil level increases, the vehicle should not be driven. In such cases, usage should be stopped immediately, and the cause of the oil level increase should be inspected. The vehicle can only be used again after the issue is resolved. Below is an introduction to engine oil: Impact of increased engine oil: Excess oil can affect the operation of the catalytic converter. Additionally, high oil pressure may cause damage to seals and lead to intense agitation of the crankshaft and connecting rod big end during engine operation. This not only increases internal power loss but also results in more oil splashing onto the cylinder walls, leading to oil burning and consumption. Function of engine oil: The engine is the heart of a vehicle, containing numerous metal surfaces that move against each other. These components operate at high speeds under harsh conditions, with working temperatures reaching 400 to 600 degrees Celsius. Under such extreme conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life.
Last time I went for car repair, I encountered a very typical case. A Civic owner found the engine oil was two centimeters above the maximum mark and smelled like gasoline. When the mechanic opened up the engine, it turned out the piston rings were worn out, causing gasoline to leak into the oil pan. This kind of oil dilution issue should never be taken lightly. I’ve personally seen owners who delayed repairs end up spending over 8,000 yuan on major engine overhauls. When oil gets diluted, its lubrication effectiveness drops significantly, and engine cylinder scoring is no joke. Now, during every maintenance session, I make sure to watch the mechanic check the dipstick. If any abnormality is found, I immediately inspect the crankcase ventilation valve and fuel injector seals. After all, the cost of repairing an engine could buy several barrels of top-tier engine oil.
