How to maintain a sometimes-used vehicle?

처리 내용

Rule(s) of thumb: Drive the car once a week, long enough to get the engine to normal operating temperature. Change the oil every 3,000 miles, or since you are not driving much, every 3 months. If your car stays stationary for very long times you need to be concerned about dry rot or the rubber on the tires, but if you follow #1, you won't need to worry about this. About once a month drive the car for an extended time (>30 minutes), there can be water accumulation on sensors and exhaust as well as rust on brake rotors. You want to heat up the entire car including engine & exhaust system to evaporate any condensation to prevent rust buildup and clean the brake rotors to maintain the ability to stop. If the gas in the tank will be there for more than a month you need to put a gas stabilizer in the tank (à la STA-BIL) so that the gas does not degrade.
