How often should engine oil be added?
2 Answers
How often engine oil should be changed depends on the vehicle's mileage and the type of oil used. Typically, engine oil needs to be replaced every six months during regular vehicle maintenance. If semi-synthetic oil is used, it should be changed every 7,500 kilometers. Engine oil is mainly divided into three types: full synthetic, semi-synthetic, and mineral oil. More details are as follows: 1. Engine oil, also known as engine lubricant, lubricates and reduces friction in the engine, aids in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption. It is often referred to as the 'blood' of a car. 2. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics. Additives are an essential part of the lubricant.
I've been driving for over 30 years. Oil changes generally follow the manual's recommendation – every 5,000 to 10,000 miles or every 6 months. Back when I drove older cars, conventional mineral oil needed changing almost every 3,000 miles. Now with full synthetic oil and improved technology, it can last 7,500 or even 12,000 miles between changes. But don't just rely on mileage numbers; factor in driving habits too. Frequent highway driving, towing, or dusty road conditions accelerate oil degradation – I recommend early inspections in these cases. Check the dipstick monthly: safe if oil level is normal and color is light amber. If it turns dark and murky, change it immediately without delay. High-mileage vehicles also require more frequent maintenance. Skimping here risks engine failure – not worth the savings. Developing regular oil change habits extends your car's lifespan – simple yet effective.
