Wax and ice
Diesel wax can restrict flow in cold conditions; water can freeze and cause a different blockage. Ask the fuel supplier about the product’s cold-weather properties and investigate the actual restriction before selecting a remedy.
Operations guide
Prepare your fuel installation for winter
Review fuel grade, stored water and the complete dispensing route before cold weather disrupts the operation.
Practical guidance
Different causes can produce similar symptoms
Slow delivery or a blocked filter does not, by itself, identify the cause.
Fuel already in storage
Check the specification and delivery date of remaining stock before replenishment. A new seasonal delivery does not automatically establish the cold-weather performance of the mixed contents.
AdBlue equipment
Use the fluid supplier’s temperature guidance and the supplied tank’s heating and insulation instructions. Do not dilute AdBlue or add antifreeze to it.
Safe diagnosis
Do not use an open flame or improvised heater on fuel equipment. Stop using damaged or leaking equipment and follow the site’s isolation and reporting procedure.
Practical guidance
A pre-winter review
Use this checklist with the manufacturer’s maintenance instructions and the site’s risk assessment.
| Area | Practical check |
|---|---|
| Fuel supply | Confirm the ordered grade, likely lowest operating conditions and delivery contingency with the supplier. |
| Tank and water | Arrange the appropriate condition/water checks; inspect accessible caps, seals and containment through the maintenance plan. |
| Filters and dispensing | Review filter history, required spares and hose/nozzle condition. Have competent personnel check restricted delivery. |
| Power and protection | Check specified heating, insulation and electrical protection through an authorised service route. |
| Site access | Keep safe access to the filling point, controls and emergency equipment in the winter operating plan. |
| Records and escalation | Record baseline delivery performance, service findings and who to contact if flow changes or alarms occur. |
Your site
Keep the records and the equipment working together.
