Privacy & safety tip

Trip math runs locally — nothing uploaded. For sensitive files (IDs, contracts, unpublished drafts), confirm in DevTools → Network that your document is not uploaded as a multipart request.

Common mistakes to avoid

Ignoring known limits: Does not model traffic, wind, or load. Use real-world economy when you have it.
Treating an estimate as a final official figure without checking source assumptions.
Mixing monthly and annual inputs (or tax years) and trusting the first output.

Deeper look — Use real economy when you can

Window-sticker MPG is a lab story. If your trip computer says 24 mpg on the commute, use 24. Official US labels live on fueleconomy.gov.

Deeper look — Two unit systems

US mode uses miles and gallons. Metric mode uses kilometres and litres per 100 km — common in the UK, CA, and EU.

Deeper look — Ownership context

Fuel is one line. Loan, insurance, and maintenance bands sit on the Cars hub so you do not budget fuel alone.
