Diesel theft shows up in the gallons first

Reconcile every drop

Each delivery should come with a ticket that shows the gallons from the truck's meter. Write down the tank reading before and after the drop, then compare what went in against what the trucks and equipment logged.

A gap between delivered and used gallons means theft, a leak, or a bad reading. You only catch it if someone checks every week. A quarterly look tells you how much is gone, not when it left.

Make the tank hard to reach

Put the tank where the office, the gate, or a camera can see it, and light it at night. Fence it when the site allows. Lock the fill cap and the nozzle, and cut power to the pump after hours.

Machines left on a jobsite overnight are targets too. Locking fuel caps on equipment take away the easiest gallons, and parking machines inside a lit, fenced area helps more than a sign does.

Watch the level from your phone

A tank monitor that sends an alert on a sudden drop tells you the same night, not at the next delivery. Cameras do more good when they cover both the tank and the road into the site.

Pair the alerts with the delivery tickets. When the level drops on a day with no work and no drop, you know where to look and roughly when it happened.

Keep less fuel sitting open

Wet-hose fueling fills equipment straight from the distributor's truck, so less fuel sits in an open tank on a quiet site. Look for the wet hose badge on a profile and say how many machines need fuel and where they park.
