What Causes Abnormal Engine Oil Level?

[StLuke]

Abnormal engine oil level is caused by insufficient oil volume or excessively high oil level, leading to elevated oil temperature; malfunction of the oil pump; or clogging of the oil filter. Below are detailed explanations: 1. Oil volume issue: Insufficient oil volume or excessively high oil level results in elevated oil temperature. It is essential to maintain the proper oil volume for engine operation, with the oil level ideally between the upper and lower marks on the dipstick—neither too high nor too low. 2. Oil pump malfunction: If the oil pump malfunctions and delivers insufficient oil, it causes inadequate oil pressure and poor cooling. The solution is to closely monitor the oil pressure gauge to ensure the oil pump operates normally. If the oil pump fails, it is advisable to seek professional repair services rather than attempting DIY disassembly if inexperienced. 3. Clogged oil filter: When the oil filter is clogged, oil bypasses through the relief valve directly into the main oil passage. Contaminants in the oil can accelerate engine wear. The solution is to regularly clean the oil filter, replace the filter element, and ensure its proper functioning.
