Follow these simple preventative maintenance steps to make sure your trucks are ready to roll all winter long.
Proper maintenance of vehicle fuel tanks is an essential part of achieving a trouble-free, lower-cost winter operation. Most diesel fuel in the U.S. is now Ultra Low Sulfur Diesel (ULSD) and, while ULSD’s lower sulfur 
content improves our air quality, it also presents some special challenges that need to be addressed when winterizing your fuel to avoid fuel-related problems.
Here are some preventative maintenance measures to improve the operation of diesel powered vehicles in winter conditions:
1) Fuel Additives: When temperatures drop below 20 degrees Fahrenheit, add a diesel fuel anti-gel additive to your fuel tanks.
2) Winter Blend: Ensure you have quality winter blended fuel in your tank.
3) Fuel Tank: Keep your fuel tank half full. Condensation can build up in a near-empty gas tank in extremely cold temperatures, which can cause fuel line freeze-up and no-start conditions.
4) Planning Ahead: Think in terms of where the coldest point the vehicle will travel to and treat fuel/plan accordingly.
There are other parts of the vehicle systems that you should also have checked regularly to make sure they are operating in the optimal way. To learn more, download our Winter Fleet Fueling tip sheet.
