Olajcseréje

Olajcseréje, or oil change, is a crucial maintenance procedure for internal combustion engines. It involves draining the old, degraded engine oil and replacing it with fresh lubricant. Over time, engine oil breaks down due to heat, oxidation, and contamination from combustion byproducts and wear particles. This degradation reduces its ability to lubricate, cool, and clean engine components. Regular oil changes are essential to maintain optimal engine performance, longevity, and fuel efficiency.

The process typically involves several steps. First, the engine is usually warmed up to allow the oil to flow more freely. Then, the vehicle is safely lifted, and the oil drain plug is removed from the oil pan, allowing the old oil to drain out. While the oil is draining, the oil filter is usually replaced. Once the old oil has completely drained, the drain plug is reinstalled, and new, clean oil is added to the engine through the oil fill cap, up to the manufacturer's specified level.

The frequency of oil changes depends on various factors, including the vehicle's make and model, the type of oil used (conventional or synthetic), driving conditions (e.g., stop-and-go traffic, towing, extreme temperatures), and the manufacturer's recommendations. Many modern vehicles have oil life monitoring systems that alert the driver when an oil change is due. Neglecting regular oil changes can lead to increased engine wear, overheating, reduced performance, and potentially catastrophic engine failure.
