Why Change Engine Oil?
2 Answers
Reasons for changing engine oil: When new oil is added to the engine, it marks the beginning of oil degradation. The deterioration of oil leads to a decline in its performance and lubrication protection, accelerating engine wear. Engine oil has a lifespan, which is its replacement cycle. The degradation of oil is actually influenced by oxidation, and the rate of degradation is determined by the speed of oxidation. Regular oil changes are essential as oxidized substances in the oil are expelled from the engine, creating a better working environment for the engine. The commonly mentioned 5,000-kilometer maintenance interval primarily applies to mineral oils. With advancements in oil technology, the replacement cycle for engine oil has been continuously extended. Long-lasting oil has become a technical goal pursued by both automobile and oil manufacturers.
As someone who drives to work every day, I've found that changing engine oil is as essential as having regular meals. The oil lubricates engine components, reduces metal friction, prevents overheating, and also removes carbon deposits and impurities, ensuring smooth engine operation. If you skip oil changes, the oil becomes dirty and thickens, increasing engine load, raising fuel consumption, and making the car feel underpowered and sluggish when accelerating. Once, I delayed changing the oil for six months, and the engine noise grew louder—later, an inspection revealed the oil was full of black sludge. Generally, it's recommended to change the oil every 5,000 to 8,000 kilometers or every six months. I've made it a habit and just set a phone reminder. When changing the oil, I also check the oil filter to prevent debris buildup. It's a small effort that brings peace of mind, extends the car's lifespan, and avoids the hassle of a breakdown. Regular maintenance also boosts resale value, helping you earn more when selling the car. In short, making this a habit keeps your car in stable condition.
