A simple mileage log for each Turo car: odometer and miles between trips

October 22, 2026 · 3 min read · The FleetWise team · Mileageodometeroperations

Every Turo car has two kinds of miles: the ones guests drive and the ones you drive. A log that separates them takes a few minutes a month, and it saves you from guessing at tax time or when a guest disputes the mileage on a trip.

This is general information, not tax, legal or accounting advice. Which mileage records you need depends on how you deduct your cars, so ask your accountant.

What to record at every trip

Two numbers per trip are enough for most hosts:

• Odometer at the start of the trip (when the guest picks up the car).
• Odometer at the end (when the car comes back).

A photo of the dashboard at each moment is the best proof, because it carries the number and the time. If a guest ever says they were charged for miles they did not drive, you can answer in one minute.

The gap between trips is the part people forget

Take the end reading of one trip and the start reading of the next. If they are the same, nothing happened in between. If they differ, somebody drove the car: a cleaner, a mechanic, you moving it to the airport, a trip to the gas station, or a personal errand.

Those miles are not guest miles, and they are not all the same kind either. Write down a short reason for each gap:

1. Cleaning or preparation
2. Maintenance or repair
3. Fuel or charging
4. Delivery or repositioning
5. Inspection, registration or similar errands
6. Personal use

A gap without a reason is the one that causes trouble later. If you use the car yourself, say so: it is better to see it in the log than to discover it when you calculate your business-use share.

Why it pays off

• Disputes. Start and end readings settle most mileage disagreements.
• Maintenance. Oil changes and tires are driven by the odometer, not by the calendar.
• Your cost per car. Fuel, wear and repairs only mean something when you know how many miles they cover.
• Tax records. If you deduct actual expenses, you split costs by business-use percentage, which comes from business miles and total miles. If you use the standard mileage rate, you need your business miles. Either way you need a log. Rules differ for rented vehicles and for larger fleets, so check with your accountant before relying on one method.

A 10-minute monthly check

1. Open the odometer history of each car and look for readings that go backwards. They are almost always typos.
2. Look for gaps with no reason and fill them in while you still remember.
3. Compare the latest reading with what the dashboard shows today, to catch trips that were never logged.
4. Note which cars are close to a service interval.

Where the numbers come from

Turo's detailed trip file includes start and end odometer readings for many trips, and your own dashboard photos fill in the rest. Whichever you use, keep the original file untouched and record corrections separately.

FleetWise imports start and end odometer readings from the detailed Turo CSV without overwriting readings you already verified, keeps a mileage log from every trip, and asks you for the reason when the miles between two trips do not add up. It does not decide your tax method; it keeps the log your accountant will ask for.
