The solutions for engine oil leakage in cars are: 1. Replace the damaged sealing ring; 2. Identify the leakage location and clean the oil traces at the leakage point; 3. Tighten loose bolts and replace damaged accessories. The causes of engine oil leakage include: 1. The sealing gasket at the base of the oil filter is not tight or has aged; 2. The transmission oil is overloaded; 3. The vehicle chassis is not tightly sealed due to impact; 4. The gear cover is aged or damaged; 5. The drain plug is loose or damaged; 6. The front and rear oil seals of the crankshaft are leaking. The composition of engine oil includes: 1. Base oil, which is the main component of lubricating oil and determines its basic properties; 2. Additives, which compensate for and improve the deficiencies in the performance of the base oil.

Last time I encountered an engine oil leak, I immediately parked the car and checked the dipstick. Upon finding the oil level low, I promptly added spare oil to prevent engine damage. Then I carefully inspected the undercarriage for the leak location—usually caused by a loose oil pan bolt or deteriorated/worn gasket. When attempting DIY repairs, first ensure the engine is cool to avoid burns, then try tightening the bolt with a wrench. If it still leaks, it might be due to improper oil filter installation or a failed main seal, in which case professional repair shop replacement is necessary. Reminder: Oil leaks not only waste money but can also pollute the environment. Regular maintenance checks on these seals save hassle and expenses. Always watch for oil stains on the ground while driving—early detection and treatment prevent minor issues from escalating.
