Open Source Car Maintenance Log Template
Every oil change remembered, every due date computed.
A car maintenance tracker with a full service log, cost totals, and due-soon reminders computed from your actual mileage and service history.
This is the real app, not a mockup. Whatever you enter in the demo stays in your browser and belongs to nobody.
What you get
One zip. Everything to own it.
Car Maintenance Log replaces the glovebox envelope of receipts. Record every service — oil changes, tire rotations, brakes, inspections — with date, mileage, and cost; keep the odometer current and the app computes what's due soon from real intervals (5,000 miles or 6 months for oil, 8,000 for rotations, yearly inspection) against your actual history. Multiple vehicles, lifetime spend totals, and interval rules that live in one editable object. No baseline record, no fake prediction — the due-soon math is honest.
