The 3,000-mile oil change is a leftover from carburetors and conventional oil. Modern engines and oils go much further — but Michigan complicates it.
Most vehicles from the last 15 years: 5,000–7,500 miles on synthetic-blend, up to 10,000 on full synthetic — per your owner's manual. Many newer cars have oil-life monitors that actually track engine conditions; trust them more than the sticker on your windshield.
Check your manual's fine print: short trips where the engine never fully warms, stop-and-go traffic, sub-freezing starts, and dusty gravel roads all fall under the severe schedule — which is most of us, most of the year. Severe schedules typically cut the interval by a third. A car that "only goes to the store" is often harder on oil than a highway commuter.
Oil degrades sitting still — moisture accumulates, additives break down. Even low-mileage cars should get fresh oil every 6–12 months.
Once a month: engine cold, pull the dipstick, wipe, reinsert, read. You're checking two things — level (between the marks) and condition (amber-to-brown is fine; black and gritty, or milky, means come see us). Many modern engines quietly consume oil between changes; catching a low level saves engines.
