Close every leak — theft, idle burn, driving style, engine health, route variance and short-fills — and turn 5–10% of your annual fuel spend back into margin.
Fleets reduce fuel costs by making every litre attributable — detecting theft and short-fills, separating idle burn from running consumption, correcting driving style, maintaining engine health, and eliminating route variance. Most fuel loss is not theft, which is why a fuel sensor on its own closes only part of the gap.
Fuel loss has six causes across three data streams. A tank sensor sees the litres go. It cannot tell you whether the engine burnt them standing still, whether a worn injector is drinking them, or whether the driver's right foot is spending them. GPS ships inside the fuel sensor and the OBD device — so location and route context need no separate tracking product. Reducing fuel cost is a question that needs three products to answer.
Only one of them is theft. That is why fleets that buy a fuel sensor and stop there recover a fraction of what is actually leaking. Scroll the six — the ledger keeps score.
Siphoning during trips, halts and overnight parking — cross-checked against ignition, position and invoice before anyone is accused of anything.
A drop that survives the ignition, position and invoice check.
Engines running while the vehicle stands still — invisible unless idle consumption is separated from running consumption, which needs ignition and engine state, not just a tank level.
Idle burn separated from fuel actually spent moving freight.
Aggressive acceleration, hard braking, sustained over-speeding. A fuel sensor sees the consequence. Only behaviour data sees the cause — and only coaching changes it.
A worn injector, a clogged filter, a drifting turbo. Mileage falls 8% across a quarter and nobody notices, because there is no benchmark to fall from. This is an OBD question, not a fuel question.
Mileage drifting below the per-model benchmark — 3.4 → 3.1 km/l over a quarter.
The same lane, run three different ways. Detours, unplanned halts, avoidable kilometres — diesel spent on distance that was never in the plan. GPS is already in the fuel sensor and OBD, so it needs no separate tracking product.
The invoice says 180 litres. The tank took 164. Sixteen litres, at a named pump, on a named date — a line item nobody was reconciling.
Invoice-to-tank reconciliation — 16 L short, at a named pump.
One of these six is theft. The fuel sensor you were about to buy sees that one — about ₹44 lakh with short-fills. The other ₹73 lakh (idle, driving style, engine health, route) lives in OBD and behaviour data. That is the entire argument for running fuel as a programme, not a device.
Same calculator as the product page, with one difference: the recovery is split by the product that earns it. Use it to decide what to deploy first.
Each one closes a different leak. Deploy them in the order your leakage profile demands — the calculator above tells you which. GPS is built into the fuel sensor and OBD device, so there is no separate tracking product to buy.
Continuous tank readings, stitched to ignition, GPS and the refuel invoice. Every litre placed on a timeline you can defend when the transporter disputes it.
Engine load, RPM, fault codes and health — with GPS on board. It separates fuel the engine burnt from fuel that simply left, and catches an injector quietly drinking 8% of your mileage.
Harsh acceleration, hard braking, over-speeding, clutch riding. The right foot is the second-largest line on this page — and the only one that responds to a conversation.
Each product you add does not just close its own leak. It makes the ones below it more accurate — because it removes an explanation.
A drop is flagged. But it could be siphoning, idling, a heavy right foot or a worn injector — and a drop you cannot explain is a drop you cannot recover.
Ignition off, no load, no fault. Forty-two litres did not go into combustion — so they went into a jerrycan. OBD is what turns a level drop into an accusation that holds.
The same lane, the same truck model, the same month. One runs 3.9 km/l and one runs 3.1. The gap now has a driver, a route and an engine attached — and every litre has somewhere to go home to.
This is why fuel is a use case and not a product. The tank tells you the fuel is gone. It takes three data streams to tell you where it went — and only together do they get it back.
Fuel cost is not a switch. It is a programme with a sequence — and the sequence matters, because each phase makes the next one measurable.
Sensors and OBD on the fleet. Theft and short-fills surface immediately, because they are the leaks that need no baseline — a tank that empties while the ignition is off is not ambiguous.
Thirty days of clean data gives you a per-lane, per-model mileage baseline. Now idle burn, driving style and engine degradation have something to be measured against — and coaching can begin.
Route variance and halt burn come out. Every exception is routed to a named owner with an SLA clock, and the fuel number stops being a monthly surprise and becomes a managed line.
Fleets reduce fuel costs by making every litre attributable: detecting theft and short-fills, separating idle burn from running consumption, correcting harsh driving, maintaining engine health, and eliminating route variance. Most fuel loss is not theft, so a fuel sensor alone closes only part of the gap.
Fleets typically recover 5–10% of annual fuel spend once theft, idle burn, driving style, engine health and route variance are each measured and attributed to an owner. On a 120-truck fleet spending ₹4 crore a year, that is roughly ₹1 crore.
No. A fuel sensor shows that fuel is missing. It cannot tell you whether the cause was siphoning, idling, driving style, a degraded injector or a longer route. Reducing fuel cost requires fuel data combined with OBD engine data and driver behaviour — with GPS already built into the fuel sensor and OBD device.
Fuel Monitoring detects theft, short-fills and idle burn. Vehicle Intelligence (OBD) surfaces engine health and mileage degradation, and its built-in GPS covers route and location. Driver Behaviour Intelligence corrects harsh driving and over-speeding. Together they close all six sources of fuel loss.
Theft and short-fill recovery typically begins in the first month, because those leaks need no baseline. Idle and driving-style savings compound over two to three months of coaching. Engine-health mileage recovery follows the service cycle.
