Mineral Oil Change Interval?
3 Answers
Generally, the replacement interval for mineral oil is 5,000 kilometers or six months. It is recommended that car owners perform vehicle maintenance and change the oil in advance to better protect the engine. Below is relevant information about engine oil: 1. Classification: Engine oil is divided into three types: full synthetic oil, semi-synthetic oil, and mineral oil. 2. Mineral oil: The base oil of mineral oil is refined from petroleum, with irregular molecular sizes and shapes. It is the lowest grade among engine oil classifications, and its performance characteristics and service life are inferior to those of semi-synthetic and full synthetic oils.
For mineral oil change intervals, I generally recommend changing it every 5,000 kilometers or every six months. For example, I've been driving for five years, mainly for urban commuting, and I change it whenever I reach this mileage. Mineral oil is prone to oxidation and impurity accumulation. Short-distance driving, such as daily commuting, can shorten the interval to around 4,500 kilometers. The last time I checked the dipstick and saw the oil color turning black and thickening, I had to change it earlier. You should also pay attention during hot weather, as high engine temperatures accelerate oil degradation. The key point is to refer to the vehicle manual's recommendation. My old car specifies 5,000 kilometers as the optimal interval for mineral oil. Delaying the change may lead to increased engine wear and noise. Remember, regularly checking the oil condition can prevent major repair costs—it's simple and worry-free.
The replacement interval for mineral oil is typically every 5,000 kilometers or six months, but this depends on your driving habits. If you frequently drive on highways with good road conditions and low engine load, the interval can be appropriately extended to 5,500 kilometers, but ensure the oil pressure remains normal. Personally, since I rarely take long trips, I change the mineral oil every 5,000 kilometers on schedule—it saves money and protects the engine. Oil viscosity degrades with temperature fluctuations, and aging accelerates in summer or cold northern climates. Before starting the engine, check the oil color and accumulated impurities; if it appears cloudy or black, it's time for a change. During maintenance, it's best to inspect the air filter as well to extend oil life and prevent minor issues from accumulating.
