Where the fuel went. And which fills to question.

Fuel is the largest running cost of most equipment and the least examined. Solmex records every fill-up against the machine that took it, measures that machine against its own history, and tells you which entries deserve a second look.

Fuel management

Fifty fill-ups, one grid, one save.

The fuel clerk types down a grid, one row per machine, and saves once. A reading below the last one is refused, an unusual quantity is held for confirmation, and the whole save can be undone for fifteen minutes. A year of old fuel logs comes in from a spreadsheet, checked as a whole before anything is written.

BASELINE

Each machine against itself

A water truck and an excavator share no sensible benchmark, so each machine is measured against its own median: liters per hour, or liters per 100 km for road vehicles. A fill more than 20% away is a warning, more than 50% is critical. Neither blocks the save; the person at the pump knows which it is.

Fills needed before a baseline3
EXCEPTIONS

A register of what to investigate

Fifteen checks run over the period: burn far above baseline, a fill larger than the tank, a meter that did not move, a price well above the median, a gap that suggests a fill was never logged. Each finding names its fill-up and states its evidence in a sentence. Checks that would need data Solmex does not hold, such as receipts, are listed as not run rather than quietly passed.

STATIONS

Stations, prices and a printed report

Keep a register of your own depots, bowsers and outside filling stations, each with its current price per liter. Compare volume and price between them, see cost by project and by equipment group, and hand management a typeset A3 report with the period's consumption, cost, exceptions and ranking.

Questions about fuel management

01How does Solmex detect abnormal fuel consumption?

It compares each fill-up's burn rate with that machine's own median over its recent fills, using the hour meter or odometer reading taken at the pump. More than 20% away is a warning and more than 50% is critical. A machine needs at least three measured fills before it is judged at all, so a new machine is never flagged on a guess.

02Can it tell when a fill-up was never recorded?

When the tank capacity is stated, yes. A machine cannot burn more between two fills than its tank can hold, so an interval that implies more means a fuelling went unrecorded. Consumption far below a machine's baseline is reported as possibly incomplete records too, because fuel does not un-burn. Solmex flags the gap; it never estimates the missing liters.

03We fuel from our own tank and from outside stations. Can both be tracked?

Yes. The station register holds three kinds: your own depot, a mobile bowser and a third-party filling station, each with its own price per liter. Every fill-up names its station, so volume, price and price drift are compared between them, and the cost of each fill posts to the cost ledger against the machine.

04Can fuel be entered days after it was taken?

Yes, within a limit your company sets. A late entry asks for a reason, and its meter reading is checked against the records on either side of that date rather than against today's meter, so an honest late entry is accepted and an impossible one is refused with the name of the record it contradicts.
