Owner's manuals assume ideal conditions. Baltimore driving — short trips, stop-and-go traffic on I-95 and Annapolis Rd, road salt in winter, humid heat in summer — is closer to what manufacturers call severe service. Here is how we think about maintenance intervals for cars we see every week.
Oil and filter
Follow your manufacturer's interval, and lean toward the shorter end of the range if most of your driving is short city trips. Short trips never fully warm the engine, which lets moisture and fuel dilute the oil. If you are unsure what your engine takes, bring the vehicle in and we will check the specification for you.
Tires, rotation, and alignment
Rotate tires regularly and check pressure monthly — pressure drops noticeably when Maryland temperatures fall. Baltimore potholes knock alignment out of spec, so if the car pulls to one side, the steering wheel sits off-center, or you see feathered wear on the tire edges, ask for an alignment check.
Brakes and fluids
Stop-and-go traffic wears pads faster than highway miles. Have brakes inspected whenever tires come off, and have coolant, brake fluid, and transmission fluid checked at least once a year. Catching a small leak early is almost always cheaper than replacing the part it starves.
Winter salt and rust
Maryland road salt attacks brake lines, exhaust, and suspension components. Rinsing the underbody after storms helps. During any service we look at those areas and tell you what we see, with photos when it helps you decide.
