Mineral oil can be used for up to six months at maximum. It can be replaced based on the following conditions: 1. Color of the oil: If the color becomes much darker than before, or if obvious impurities are found floating on the surface, it indicates that the oil needs to be replaced. 2. Vehicle feel for judgment: If the engine vibration becomes noticeably stronger and the engine noise increases, it is necessary to go to a 4S shop as soon as possible to replace the oil. Relevant information about mineral oil is as follows: 1. Mineral oil: It is a lubricating oil refined from petroleum. The base oil of mineral oil is the residual bottom oil left after the distillation of useful light substances (such as aviation oil, gasoline, etc.) in the crude oil refining process, which is then further refined. 2. Characteristics: Mineral oil is the most common type of lubricating oil on the market. Although mineral oil is inexpensive, its service life and lubrication performance are inferior to semi-synthetic and synthetic oils.

















How long can mineral oil last? With decades of driving experience, I feel it shouldn't exceed six months or 5,000 miles. When I was young and lazy, I delayed once and ended up with degraded oil—the engine buzzed loudly, costing me much more for an overhaul. Mineral oil oxidizes quickly, deteriorating faster in city traffic or during short trips when the engine starts frequently. The oil turns black and thickens, drastically losing its protective properties. I recommend keeping a small notebook in the car to log oil change dates and regularly checking the dipstick—if the color darkens, act promptly. Although synthetic oil is popular now, mineral oil is cheap and widely available. Changing it frequently ensures safety and reliability, avoiding major issues. Remember, safety comes first—don't gamble with delays. I've stuck to this habit and never had a problem.

My family and I love DIY car . Mineral oil is cost-effective, but the longest I've tried is six thousand miles, when the oil became sticky with a strange odor—a clear danger sign. Saving money is fine, but don't overdo it. I change it every five thousand miles to ensure engine longevity. Doing oil changes yourself is simple and saves money—with the right tools, it takes just twenty minutes without much effort. The key is to monitor driving habits: on smooth highways with good conditions, it can last longer, but don't push it in city traffic. I check the oil dipstick for cleanliness and change it as soon as it looks cloudy. In short, balance economy and maintenance—don't take risks.

I drive to and from work in the city every day, stuck in traffic. How long can mineral oil last under such conditions of frequent short-distance starts and stops with high wear? Based on experience, it needs to be changed at most every three months, as the oil oxidizes and degrades quickly, turning dark in color. Don't believe those who claim it can last longer—cold engine starts accelerate wear. I regularly check the dipstick and take immediate action if I find excessive impurities. Safe driving is the core; changing oil early saves both peace of mind and money.

I often go on long-distance business trips, and mineral oil can last longer under relatively mild highway conditions, such as 6,000 to 7,000 miles without issues. The engine temperature remains stable, and the oil quality degrades more slowly. I also check to ensure the oil color stays clear. However, don't exceed six months—keeping it too long isn't stable either. Don’t skip regular out of laziness; otherwise, once problems arise, the repair costs will be much higher and cause delays.

I live in the cold north where winters freeze, and mineral oil thickens at low temperatures, offering poor protection. It's recommended to change it every four months regardless of mileage. Cold seasons make starting difficult, and oil quality degrades quickly, so be cautious. I change to fresh oil before winter to ensure smooth engine operation. Summers are slightly better, but don't wait more than six months. Keeping simple habits avoids major repairs, and safe driving is crucial.
