As winter temperatures drop, diesel engines, fuel systems, and critical components face increased stress. To keep BDJ Trucking Co. operating safely and efficiently, all drivers and maintenance personnel must follow the winter-prep guidelines below. Proper preparation reduces breakdowns, prevents fuel issues, and ensures our fleet stays mission‑ready during the coldest weeks of the season.
- Keep Fuel Tanks Topped Off Before Major Snow or Deep Freezes
A full tank helps prevent condensation inside the fuel system—a leading cause of fuel gelling and filter plugging in subzero temperatures.
- Less air in the tank = less moisture
- Less moisture = fewer cold‑weather shutdowns
If severe weather is forecasted, fuel up before the storm to avoid unnecessary downtime.
- Use Proper Winter‑Blended Diesel
Winter diesel is not the same as summer diesel. Using the correct blend is essential to prevent gelling, hard starts, and fuel‑flow issues.
Winter fuel provides:
- Improved cold‑weather flow
- Reduced filter plugging
- Better reliability in freezing temperatures
BDJ drivers must ensure they are fueling with approved winter‑grade diesel during the season.
- Replace Fuel Filters Before Temperatures Drop
Old or partially clogged filters gel faster and restrict fuel flow.
A fresh filter helps:
- Improve cold starts
- Reduce downtime
- Protect injectors and fuel pumps
This step is especially critical for trucks running continuous or high‑demand routes.
- Prevent DEF From Freezing
Diesel Exhaust Fluid begins to freeze at 12°F (-11°C). To avoid system faults or delays:
- Store DEF indoors or in heated areas
- Use heated totes or pumps for high‑volume operations
- Keep extra DEF stocked before extreme cold snaps
Frozen DEF can delay operations and trigger avoidable maintenance issues.
- Inspect Fuel Storage Tanks & Monitoring Systems
Cold weather magnifies small issues in storage systems. All tanks and monitoring equipment should be checked regularly.
Confirm the following:
- Vent caps and lids are fully secured
- Monitoring systems and sensors are reading correctly
- Ice and snow are cleared from access points
Proactive inspection prevents contamination, misreads, and fueling delays.
- Prepare Backup Generators Before the Freeze
For locations where power reliability is essential—offices, shops, yards, and support facilities—ensure generators are winter‑ready.
Key steps:
- Top off generator fuel tanks
- Inspect filters, lines, and connections
- Run a test cycle before extreme cold arrives
A prepared generator ensures BDJ operations remain uninterrupted during outages.
BDJ Safety Reminder
Winter conditions demand extra attention, preparation, and discipline. Following these steps keeps our fleet protected, our drivers safe, and our operations running strong throughout the season.
