Switch from Fuelly to Car Log

Years of fuel-ups are worth moving carefully. Car Log imports Fuelly's real CSV exports — tested against genuine exports, not just the documented format — so your history arrives intact.

How to import your Fuelly history

Sign in at fuelly.com and export your data: each vehicle's page offers CSV exports of fuel-ups and services. (The mobile app doesn't export — use the website.)
Get the files onto your iPhone — AirDrop, iCloud Drive, or email them to yourself.
In Car Log, open Settings → Import, pick the file, and check the preview. Columns are mapped for you, and you can adjust them before anything is written.
Import. You'll get a count of exactly what came in, and malformed rows are reported — never silently dropped.

What comes across

Every fuel-up: date, odometer, volume, price, partial-fill flags, and station names (Fuelly's brand column).
Your service records, with Fuelly's service types mapped to Car Log's.
US, metric, and UK exports — litres and km headers are recognized, and a km export sets the vehicle's units automatically.
Trip-tracked vehicles (Fuelly exports without an odometer column): distance-per-tank is preserved and your fuel economy still computes.
Legacy Gas Cubby data, which Fuelly exports in the same format.
Spend totals: Fuelly's exports don't include a total-cost column, so Car Log derives it (volume × price) — your cost stats aren't zeroed.

One quirk worth knowing: Fuelly exports volume and distance in whatever display units your Fuelly account is set to, while the odometer column stays in the vehicle's native units. Before exporting, set your Fuelly display units to match the vehicle so the file is internally consistent.

Why people move

Fuelly earned a decade of loyalty, but the iPhone app has gone a long time without updates. If you're moving on, the thing that matters most is that your history moves with you — losslessly. In Car Log, importing is free, your records stay on your device with automatic iCloud backup, and CSV export back out is free. No account required.
