What should I do if my car is leaking oil: 1. Replace the filter screw; 2. Sprinkle water on the hub to cool it down; 3. Replace seals such as oil seals and gaskets; 4. Add lubricating oil; 5. Check and clear the vent plug and check valve; 6. Replace thin-walled parts like side covers; 7. Tighten or replace nuts. The reasons for oil leakage are: 1. Uneven tightening force of nuts, stripped threads, or loose and falling off causing failure; 2. Excessive wear, aging, or deformation of sealing materials; 3. Insufficient lubricating oil; 4. Warping deformation of component joint surfaces or shell damage causing oil leakage; 5. Blockage of vent plugs or check valves.
Last time I was driving on the highway and noticed oil dripping from the chassis, which really scared me. I immediately pulled over, turned on the hazard lights, and squatted down to check the color of the oil stains—black indicates engine oil, red is transmission fluid, and green coolant is the most dangerous. Never try to start the engine again; calling for a tow truck is the safest option. Once, I thought it was just a loose oil filter, but after taking it apart, I found out it was a worn-out rear crankshaft oil seal. I recommend having the repair shop first check the sealing gasket and oil pan bolts, as leaks in these areas are quite common. You can keep some oil-absorbent cotton on hand for emergencies, but never try to patch it up with tape, as it can cause bigger problems. Remember to take photos of the leak location to show the technician—it can save a lot of diagnostic time. Don’t hesitate to pay for the tow truck; safety comes first.
