The main purpose of engine oil is to lubricate the moving parts of the engine, such as the pistons, rings, bearings, and camshaft. This helps to reduce friction and wear, which can extend the life of the engine. Oil also helps to cool the engine by absorbing heat from the metal surfaces and carrying it away to the oil cooler. In addition, oil helps to remove contaminants from the engine, such as dirt, metal shavings, and soot.
Engine oil is typically changed every 3,000 to 5,000 miles, or every six months to a year. However, this interval may vary depending on the type of oil used, the type of engine, and the driving conditions. It is important to check the oil level regularly and add oil as needed to keep the engine properly lubricated.
