How Long Can Mineral Oil Be Used at Maximum?
2 Answers
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.
