Why Should Engine Oil Be Changed?
1 Answers
Engine oil effectively protects the moving parts of an engine. Here is a detailed explanation of why car engine oil needs to be changed: 1. Lubrication: The primary function of engine oil is lubrication. It forms an oil film on the metal surfaces of the engine, reducing wear between metal parts. 2. Cleaning: It breaks down sludge and deposits generated during engine operation, keeping the engine internals clean. 3. Rust prevention: It neutralizes acidic substances produced during engine use and forms a rust and corrosion-resistant layer, preventing metal parts from rusting and corroding due to oxidation. 4. Sealing: It seals the gaps between pistons and cylinders, ensuring complete fuel combustion and improving fuel efficiency. 5. Cooling: It dissipates high temperatures generated by engine wear, protecting various engine components.
