What is the classification standard for Mobil engine oil grades?
1 Answers
Mobil engine oils are classified from premium to economy series as follows: Mobil 1 series, Mobil Super series, and Mobil Special series. Lubrication function: Maintains viscosity between cylinders and pistons for proper operation, reduces friction between components, and minimizes wear. Cooling function: Assists the vehicle's cooling system in lowering the temperature of the engine's internal environment to some extent. Cleaning function: Removes sludge, carbon deposits, and other impurities attached to engine components. Sealing function: Seals gases within the engine pistons and piston rings, reducing the ingress of external contaminants. Rust and corrosion prevention: High-quality oil adheres to component surfaces, preventing contact with air, acidic substances, and harmful gases, thereby protecting engine parts from corrosion by atmosphere and water. Shock absorption: When pressure at the engine cylinder ports increases suddenly, placing heavy loads on pistons, piston rings, connecting rods, and crankshaft bearings, the lubricated transmission through bearings helps cushion the impact loads.
