Does Exceeding the Upper Limit of the Oil Dipstick Have Any Impact?

[VonCali]

Exceeding the upper limit of the oil dipstick does have an impact. If the oil level surpasses the upper limit mark on the dipstick, it is recommended that the owner drain some oil out. Otherwise, it will increase the resistance during engine operation and may potentially damage the three-way catalytic converter. Engine oil is often referred to as the lifeblood of the engine, as it plays roles in lubrication, cleaning, sealing, heat dissipation, cushioning, and rust prevention within the engine. Without engine oil, the engine cannot function properly. When adding oil, it is only necessary to ensure that the oil level is between the min and max marks on the dipstick. The oil level should not fall below the min mark, as this could lead to insufficient lubrication in the engine.
