In a taxi fleet, fuel is usually the heaviest expense after the vehicle itself, and also the least managed. Each driver fills up when they can, wherever is close and as much as they can afford; the owner sees the total at the end of the week and accepts it as a fixed cost of the trade. When the price goes up, the only response discussed is raising fares, and almost nobody asks how much of that spending could be avoided.
The thesis of this article is that a significant part of a fleet's fuel spending doesn't come from trips but from what happens between them: empty kilometers, waiting with the engine running, improvised routes and poorly maintained cars. That part can be reduced through operating decisions, without touching the fare and without asking the driver to work more. And what it saves stays in the pocket of whoever pays for the fuel, which is often the driver.
Where the fuel really goes
If you ask a driver to guess how much of their fuel goes into trips with a passenger, they'll almost always say most of it. When it's measured, the split tends to surprise. A considerable share is spent going to pick up the passenger, returning to an area with demand after a long trip and driving around aimlessly waiting for the next request. None of those kilometers is paid.
- Kilometers to the pickup point, especially if the assignment radius is very wide.
- Aimless driving between trips, looking for where demand is.
- Empty returns after long trips or trips outside the city.
- Waiting with the engine running, especially with the air conditioning on.
- Longer routes from not knowing the area or avoiding traffic unnecessarily.
- Extra consumption from low tires, dirty filters or an overdue tune-up.
The good news is that almost all these points depend more on how the operation is organized than on the driver. A driver doesn't decide the assignment radius or know where demand will be in an hour; dispatch can know that. That's why fuel savings is, above all, the operator's job.
Reducing empty kilometers
The first front is the distance to the passenger. If the operation assigns trips to drivers who are very far away, each trip starts with several unpaid kilometers. Review the usual assignment radius and how far, on average, a driver travels to reach the pickup point. Sometimes adjusting that radius during hours with many drivers online saves more fuel than any driving tip.
The second front is driving around between trips. A driver who doesn't know where demand will be tends to keep moving so as not to sit still, and every loop costs fuel. Sharing with the fleet, in a simple way, which areas and hours usually concentrate demand lets them park at a good spot and wait with the engine off. Standing still in the right place is more profitable than moving aimlessly.
The third is empty returns. A long trip to the outskirts or to another city can be good, but only if the return is charged or there's a chance of getting a trip back. Set a clear rule for those trips and explain it to drivers, so they don't have to decide on their own whether it's worth accepting.
Driving and waiting: the habits that matter most
Without turning it into a lecture, it's worth sharing with drivers the habits that most affect consumption. Accelerating and braking smoothly, keeping a steady speed on avenues and not leaving the engine running during long waits are small changes that, added up over a month, show in the spending. What matters is presenting them as what they are: money that stays with the driver.
Air conditioning deserves a separate mention, because in hot cities it's part of the service and passengers expect it. The key isn't turning it off during the trip, but not running it with the car empty and parked for half an hour. A driver who waits in the shade with the engine off and turns on the air when the passenger gets in offers the same service with far less spending.
We asked drivers to stop driving around between trips and gave them three waiting points per area depending on the time. After a month, several told us they were spending considerably less on fuel and doing almost the same number of trips. It was easier to convince them with their own fuel receipts than with any explanation.
Maintenance is also fuel
A car with low tires, a dirty air filter or an overdue tune-up consumes more without anyone noticing. These are small daily losses that, in a vehicle covering many kilometers a week, end up costing more than the maintenance itself. Including a tire pressure check in the weekly routine and sticking to the tune-up schedule is a direct way to save fuel.
If the car belongs to an owner and a driver operates it, make clear who's in charge of each check. When nobody is responsible for tire pressure, nobody checks it, and the extra fuel is paid by whoever fills the tank. A short list of weekly checks, with someone responsible for each, avoids that gray area.
It also helps to review what the car is carrying. A trunk full of tools, water jugs or things the driver no longer uses adds weight every day and translates into higher consumption. Clearing out what isn't needed takes five minutes and doesn't affect the service the passenger receives at all.
Who pays for fuel changes the incentive
In many regional fleets the driver pays for fuel out of pocket, and in others the car owner pays. That difference completely changes who has an interest in saving. If the driver pays, any operating improvement that cuts empty kilometers reaches them directly as more earnings, and they usually adopt it quickly. If the owner pays, the driver has little reason to watch consumption, and it's worth agreeing on some way to share the savings.
A simple formula is to set a reference consumption per car and split between owner and driver whatever is saved below that figure. It doesn't need to be exact; it's enough that both see that looking after fuel benefits them both. What doesn't work is one party paying while the other decides how it's spent, with no rule to align them.
Measuring without overcomplicating it
You don't need a sophisticated system to know whether the fleet is overspending. It's enough to compare, per car, how many kilometers it covers per liter and how much it spends on fuel per completed trip. If one car spends much more than similar ones, something's going on: a mechanical problem, a driving habit or a way of working with too many empty kilometers.
Do it once a month and share the results with drivers constructively, without singling anyone out. The question isn't "why do you spend so much?" but "what's different between your way of working and that of whoever spends less?". Often the answer is a better waiting area or a simple habit that can be copied.
When fuel prices go up, that record also helps you decide with data. If you've already cut empty kilometers and the cars are well maintained, you'll know precisely how much fuel weighs in each trip and whether the fare really needs to change. Raising prices without reviewing what's being wasted passes on to the passenger a cost the operation could have avoided.
What the whole operation gains
Saving fuel isn't just about numbers. A driver who spends less on fuel earns more per hour without working more, and that keeps them on your platform. An owner who sees spending drop trusts the operation more. And a fleet covering fewer empty kilometers has cars that last longer and passengers who wait less, because drivers are better positioned.
If you can only do one thing this week, measure the empty mileage of a few cars over seven days. With that number you'll know whether your biggest opportunity is in the assignment radius, the driving between trips or the maintenance. Everything else is decided better from there.
