How often should I get my oil changed? Our company agrees that a driver should have their fluid topped off every 3,000 to 7,000 miles or three months, However you can always refer back printable owner's manual which covers recommended intervals based on make and model of vehicle being driven; many new cars will tell us when they're due for service - remember: without an essential maintenance like this one (replaces lost fluids), internal cogs could turn into sludge preventing the car from running smoothly! , Visit Superior Auto Service at 12298 Wilkins Ave, Rockville, MD 20852 or call (301) 770-6662 to schedule an appointment
