What's the matter with oil leakage?
Recently, the problem of oil leakage in cars has become one of the hot topics on the Internet, and many car owners have reported similar problems on social platforms and forums. This article will analyze the common causes, detection methods and solutions of oil leakage, and provide you with a structured reference based on hot data from the entire network in the past 10 days.
1. Common causes of oil leakage

| Reason type | Specific performance | Proportion (discussion data of the entire network) |
|---|---|---|
| Seal aging | Oil pan gasket, crankshaft oil seal and other rubber parts harden and crack | 35% |
| mechanical damage | Chassis collision caused the oil pan to rupture | 28% |
| Assembly issues | The screws are not tightened or the sealant is unevenly applied after repairs. | 20% |
| Oil filter failure | The filter element sealing ring is deformed or not installed properly. | 12% |
| other reasons | Overfilling of engine oil, blisters in the cylinder, etc. | 5% |
2. Hot cases across the entire network (last 10 days)

3. How to determine oil leakage?
1.Floor oil stain inspection: After parking the car, observe whether there are fresh oil drops on the ground. The engine oil is brown-black and sticky.
2.Engine room observation: Focus on checking whether there is sludge accumulation around the oil pan, valve cover, and oil filter.
3.Oil dipstick inspection: The engine oil level is lower than the MIN mark when the car is cold, and it needs to be replenished frequently in the short term.
4. Comparison of solutions
| Processing method | Applicable scenarios | average cost |
|---|---|---|
| Replace gasket | Single seal aging | 200-800 yuan |
| Oil pan repair | slight bump deformation | 500-1500 yuan |
| Engine overhaul | Crankcase damage | 3,000 yuan+ |
| Warranty claim | Appears during the new car period | free |
5. Professional advice
1. If oil leakage is found, repair it immediately to avoid engine cylinder failure due to lack of oil.
2. Select original factory seals. Sub-factory parts may have dimensional deviations that may lead to secondary leakage.
3. After maintenance, it is recommended to re-inspect after driving 500 kilometers to confirm that no new oil stains appear.
4. During regular maintenance, technicians are required to focus on inspection of leak-prone areas to prevent problems before they occur.
6. Latest industry trends
According to data from a third-party complaint platform, complaints related to oil leakage increased by 17% year-on-year in the third quarter of 2023, of which turbocharged models accounted for 63%. Some brands have issued technical notices to upgrade high-pressure oil seal materials.
From the above structured analysis, it can be seen that the problem of oil leakage requires targeted measures based on specific causes. It is recommended that car owners choose the optimal solution based on the vehicle's condition and repair costs.
