Move your Fuelly data to SteerLog
SteerLog reads Fuelly’s CSV export directly — fuel-up dates, odometer, gallons, price, even the partial-fill flag — so years of fill-ups arrive with their fuel economy intact. Import is free, takes a couple of minutes, and your history ends up on your phone and your iCloud, not another company’s server.
Getting your data out of Fuelly
- Sign in at fuelly.com and open your vehicle’s page — exports live on the website, not the app.
- Use the vehicle’s export link to download your fuel-ups as a CSV file.
- That’s it. The file has columns like
fuelup_date,odometer,gallons,price, andpartial_fuelup— SteerLog matches every one of them by name, no editing needed.
If the export link has moved in your version of the site, any CSV of your fuel-ups works — SteerLog matches columns by name, and the full list is below.
SteerLog is the log you’ll still have in 15 years: on-device, synced to your own iCloud, exportable forever — and reminders by date and mileage land on your lock screen.
Get SteerLogImporting into SteerLog
- Get your CSV onto your iPhone — AirDrop, iCloud Drive, Files, or email it to yourself.
- In SteerLog, open Settings › Export & Import › Import CSV. The import lands in the vehicle you currently have selected, so pick the right car first.
- Choose the file. SteerLog reports how many entries were added, how many duplicates were skipped, and how many rows it couldn't read.
- Check the History tab — your entries, charts, and fuel economy are computed from the imported fill-ups immediately.
One CSV goes into one vehicle. The free tier is one vehicle with every feature; unlocking more vehicles is a single one-time purchase — no subscription.
Column names SteerLog recognizes
Matching ignores case, spaces, and punctuation — Fuel-up Date, fuelup_date, and FuelUpDate all match. Only a date column is required; everything else is optional.
| Field | Accepted column names |
|---|---|
| Date (required) | date, fuelup_date, service_date, entry_date, day |
| Odometer | odometer, odo, miles, mileage, km, kilometers, odometer_mi, odometer_km |
| Fuel volume | fuel_volume, volume, gallons, litres, liters, fuel_qty, qty, quantity |
| Price per unit | price_per_unit, price_per_gallon, price_per_liter, unit_price, price |
| Total cost | cost, total_cost, total_price, total_spent, total, amount |
| Entry type | type, entry_type, category — values like fuel, service, expense |
| Title / place | title, services, service, station, fuel_brand, location, description, name |
| Notes | notes, note, comments, comment |
| Full-tank flag | full_tank, filled_tank, full |
| Partial-fill flag | partial_fuelup, partial |
No type column? Rows with a fuel volume or unit price are treated as fuel-ups; the rest become service or expense entries. Total cost is computed from volume × price when the file doesn't carry it. European decimals are safe — an entry of 9,6 litres imports as 9.6, not 96. Re-importing the same file skips duplicates (same day, type, odometer and cost), so you can't double up your history by accident.
Questions, answered
Will my fuel economy history carry over?
Yes. SteerLog recomputes MPG (or L/100km) from your imported fill-ups, using full-to-full math. If your file carries a full-tank or partial-fill column, it is respected — partial fills are folded into the next full tank instead of poisoning the average.
Is the import free?
Yes — completely. Import, CSV/PDF export, iCloud sync, and backup files are all free in SteerLog, forever. The free tier is one vehicle with every feature; a single one-time purchase unlocks unlimited vehicles. There is no subscription.
Do I need an account to use SteerLog?
No. SteerLog has no sign-up, no login, and no company server. Your log is stored on your iPhone and synced through your own iCloud, so there is no service outage, price change, or shutdown that can take your history with it.
What happens if I import the same file twice?
Nothing bad — duplicates are skipped. SteerLog treats an entry as a duplicate when the calendar day, entry type, odometer and cost all match one it already has, so re-running an import (or importing overlapping exports) won’t double your history.
How do I import more than one car?
One CSV imports into one vehicle, so export each car separately and import each file with that car selected. The free tier holds one vehicle with every feature; unlocking your whole garage is a single one-time purchase, not a subscription.
Why the import is free
SteerLog's whole premise is that your maintenance history belongs to you: it lives on your phone and your own iCloud — no account, no company server, no subscription. Import, export, backup files, and CSV/PDF are free forever, because a log you can't move isn't yours. See how SteerLog works.
