1 Answers
Engine oil lubricates the following parts: 1. Valve train; 2. Crankshaft bearings; 3. Pistons; 4. Engine crankshaft compartment; 5. Gasoline engine pistons; 6. Hydraulic lifters and tappets. Engine oil, also known as motor lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, as well as shock absorption. Symptoms of insufficient engine oil include: 1. Insufficient lubrication in areas requiring oil splash from the engine; 2. Bearing seizure and burning of crankshaft bearings and bearing shells due to poor lubrication; 3. Abnormal engine vibration and reduced power output; 4. Malfunction of the engine's variable timing solenoid valve.
