What is the correct way to check engine oil?
1 Answers
The correct method to check engine oil is: pull out the dipstick, wipe it clean, reinsert it, then pull it out again to observe the oil level. If the oil level is between the two marks on the dipstick, it indicates the oil quantity is normal. Several points to note when checking engine oil: 1. Wait at least 15 minutes after turning off the engine to allow the oil to stabilize; 2. Ensure the vehicle is parked on level ground when checking to maintain an accurate oil level reading; 3. Wipe the dipstick clean after the first removal before reinserting it for measurement to ensure visual accuracy of the oil level. The primary functions of engine oil are to reduce friction and wear between moving parts, remove sludge and varnish from the engine, neutralize acids produced by fuel combustion and lubricant oxidation (detergent action), improve piston ring sealing, and cool the engine by carrying away heat from moving components.
