Is it dangerous to twist the oil dipstick?
1 Answers
Twisting the oil dipstick slightly won't cause any issues. The oil dipstick is used to check the oil storage level, with clear upper and lower limit marks H and L on it. H represents the highest oil level (upper limit), while L indicates the lowest oil level (lower limit). When the oil level falls below the L mark, the oil warning light will illuminate, indicating insufficient oil that needs timely replenishment. Below are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding components, thereby reducing wear. 2. Sealing: Engine oil can form a sealing ring between the piston rings and pistons, minimizing gas leakage and preventing external contaminants from entering. 3. Rust prevention: Lubricating oil adheres to component surfaces, protecting them from contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When cylinder pressure rises sharply in the engine, suddenly increasing the load on pistons, piston chips, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine components back to the oil tank through circulation, washing away dirt generated on the working surfaces of components via the flow of lubricating oil.
