It depends on what grade of oil you change. I changed the GT oil, a German brand. It costs more than 600 yuan at a time, which is expensive, but you can't just look at the oil. You have to look at it in terms of service life. You changed mineral oil for more than 200 yuan, but only ran 3000 kilometers. I replaced this with PAO base oil and liquid molybdenum additive, both of which are 65,438+05,000 km. German engine oil.
