OilTrax

OilTrax is the simplest way to keep every engine you own on schedule — cars, trucks, motorcycles, lawn mowers, tractors, generators, and any other small engine. Log each oil change in seconds and let OilTrax remind you before the next one is due, so you never guess "when did I last change the oil?" again. TRACK WHAT MATTERS • Date and mileage (or engine hours) • Oil type/viscosity, brand, and amount in quarts • Oil filter brand and model/part number • Separate purchase links for the oil and the filter — reorder in one tap • Notes for anything else you want to remember STAY ON SCHEDULE • Track by date (annual/semi-annual) or by mileage — whatever fits each vehicle or engine • Get a local reminder before each one is due, and choose how many days ahead • Clear status badges: Overdue, Due soon, or Scheduled BUILT TO BE SIMPLE • Add unlimited vehicles and equipment • Full oil-change history for each one • Light and dark mode • Works on iPhone and iPad YOUR DATA STAYS YOURS • Everything is stored on your device — no account, no sign-in, no tracking • Export all your records anytime as CSV or JSON OilTrax is a one-time, no-nonsense maintenance log. No subscriptions, no ads, no data collection.
