Diesel Shrinkage: Sealing the Biggest Leak in Plant Hire

MEASURE AT EVERY TRANSFER

In heavy machinery and mobile plant operations, fuel is often the single largest variable operating expense. The transfer point—from the mobile bowser into the machine's tank—is precisely where unaccounted litres disappear, whether through improper logging, spillage, or shrinkage.

By establishing strict measurement protocols across every fluid transfer point, fleet managers can protect operating margins and ensure fuel consumption aligns directly with machine output.

High-impact fuel controls

Issue & Return Level Logging: Record exact fuel levels during every site gate check-out and check-in to establish clear baseline usage per operational cycle. Daily Bowser Dip Reconciliation: Dip and reconcile fuel bowsers daily to match total bulk fuel dispensed against individual machine dip logs. Consumption Drift Tracking: Monitor fuel usage per operating hour and flag machines whose consumption drifts beyond normal baseline parameters.

FUEL CONTROL & MONITORING FRAMEWORK

01 Bulk Storage & Bowser Transfer • Verification Step: Daily Physical Dip & Volume Logging • Control Measure: Reconcile Total Litres Issued vs Dispensed • Margin Impact: Immediate Bulk Shrinkage Prevention

02 Bowser to Machine Refueling • Verification Step: Litres Dispensed Log & Machine Meter Capture • Control Measure: Sign-Off at Point of Tank Filling • Margin Impact: Elimination of Unaccounted Transfers

03 Consumption & Drift Analytics • Verification Step: Hour Meter vs Litres Used Ratio Analysis • Control Measure: Automated Flagging of Efficiency Anomalies • Margin Impact: Early Identification of Mechanical & Theft Issues

VISIBILITY REDUCES SHRINKAGE IMMEDIATELY

You don't need expensive hardware overhauls to stop fuel loss. Most fleet operations discover that introducing transparent, consistent logging alone curtains fuel shrinkage before additional equipment is installed.

Operational and financial benefits

Immediate Behavioral Shift: Knowing every transfer is measured and recorded deters unauthorized fuel siphoning across all job sites. Identify Mechanical Issues Early: Sudden spikes in fuel consumption per hour often signal clogged filters, faulty injectors, or engine wear. Accurate Project Job Costing: Assign exact fuel costs directly to specific contracts and project sites for true operational margin reporting.
