General maintenance schedule

These are common starting intervals, not a factory schedule for your engine. Your owner's manual always wins.

Engine oil & filter	Every 5,000 miles or 6 months Use the oil grade and spec in your owner's manual. Some engines allow longer.
Tire rotation	Every 7,500 miles or 6 months Also a good time to check tread depth and pressures.
Brake inspection	Every 12,000 miles or 1 year Pads, rotors, lines and fluid level.
Cabin air filter	Every 15,000 miles or 1 year Sooner if the airflow smells musty or feels weak.
Engine air filter	Every 20,000 miles or 2 years Sooner on dusty or gravel roads.
Wiper blades	Every 1 year
12V battery test	Every 3 years Most 12V batteries last 3 to 5 years. Test before winter.
12V battery replaced	Every 5 years Most last 3 to 5 years. Heat and short trips wear them faster.
Tires (replace)	Every 50,000 miles or 6 years Tread depth and age matter more than miles. Replace at 2/32" of tread (4/32" if you drive in the rain a lot), or around 6 years old. The date code is on the sidewall.
Brake pads (replace)	Every 40,000 miles Replace when about 3 mm (1/8 in) of pad is left, or if you hear grinding. Rear pads usually last longer than front.
Brake rotors (replace)	Every 70,000 miles Replace below the minimum thickness stamped on the rotor, or if warped or deeply grooved. Often done with new pads.
Shocks & struts (replace)	Every 75,000 miles Worn ones cause bouncing, nose-dive when braking and uneven tire wear. Many last 50,000 to 100,000 miles.
Brake fluid flush	Every 30,000 miles or 2 years Brake fluid absorbs moisture over time.
Spark plugs	Every 60,000 miles Iridium or platinum plugs often go 100,000 miles. Check the manual.
Transmission fluid	Every 60,000 miles Interval varies a lot by transmission. Check the manual.
Coolant flush	Every 60,000 miles or 5 years Some long-life coolants go 100,000+ miles.
Serpentine belt	Every 90,000 miles Inspect for cracks at every oil change.
Timing belt (if equipped)	Every 90,000 miles or 7 years Skip if your engine has a timing chain. Check the manual.
