OilTrax

Log every oil change for your cars, trucks, and small engines. Track oil, filter, mileage, and cost — and get reminded before the next one is due.

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.
