Keeping up with car maintenance: what is due when, and records that pay off
Most car trouble that costs real money starts as maintenance that slipped: oil left too long, brakes worn to the metal, a coolant change missed. Keeping on top of it takes two things — knowing what is due, and keeping a record of what was done.
Due by distance or by time, whichever comes first
Almost every service item has two limits: a distance and a time. Oil, for example, breaks down with use and with age, so a car driven little still needs it changed on time. Brake fluid absorbs moisture from the air whatever the mileage. If you drive 1,000 miles a month, the distance usually arrives first; if you drive 300, the calendar does.
The Car Maintenance Tracker watches both. From your odometer readings it works out how far you usually drive, so it can tell you not just “due at 47,000 miles” but roughly when that will be.
Where your intervals come from
Your owner's manual (or the manufacturer's maintenance guide online) has the schedule for your car. It often has two: a normal one, and a “severe” one for short trips, stop-and-go traffic, towing, dust or extreme temperatures — which describes more everyday driving than people expect. Common items to find in it:
- Engine oil and filter — widely different by car and oil; many modern cars on synthetic oil allow 7,500–10,000 miles or a year, older ones less. Many cars also have an oil-life monitor.
- Tire rotation — typically every 5,000–7,500 miles, so the tires wear evenly.
- Brakes — pads and rotors inspected at least yearly; brake fluid commonly every two to three years.
- Filters — engine air filter and cabin filter, sooner on dusty roads.
- Coolant, transmission fluid and spark plugs — long intervals, easy to forget.
- Timing belt — only engines that have one (many use a chain); expensive if it breaks.
- Wipers, the 12-volt battery, registration and inspections — yearly checks worth a reminder.
Electric cars skip oil, spark plugs and most filters, but still need tires, brakes, brake fluid, cabin filters and coolant for the battery.
Why the records matter
- Warranty claims. In the US, the Federal Trade Commission says you do not have to use the dealer for maintenance to keep a warranty: it is illegal to deny coverage because routine work was done by someone else, and using aftermarket parts does not void it. But the warranty company can ask for maintenance records — so keep them, including for work you did yourself.
- Extended warranties and service contracts often require the manufacturer's maintenance to be followed and may ask for proof.
- Selling the car. A complete history with receipts answers a buyer's first question and supports your price.
- Your mechanic. Knowing when the brakes, fluids and parts were last done saves paying to do them twice.
A good record has the date, the odometer reading, what was done, who did it, what it cost, and the receipt. Parts, oil type and part numbers in the notes help later.
Keeping it up without effort
- Log it at the counter. Scan the receipt before you drive away — the tracker reads the date, mileage, total and work done from the photo on your phone.
- Note the odometer now and then, at fill-ups, so due dates stay accurate.
- Put due dates in your calendar, with a week's warning.
- Check for recalls with your VIN — in the US on NHTSA's recalls page — since recall repairs are free.
- Back up the history now and then; a backup restores everything, receipts included, on any device.
