The yearly change in seasons affects the type of maintenance needed to care for your vehicle. In addition to swapping out winter tires and packing away the ice scraper, the transition from cold weather to the heat of summer also affects diesel fuel. The professionals at State Fuel Company in Rochester, NY, explain everything you need to know about using this fuel in different seasons.

How Does Winter Affect Diesel Fuel?

When exposed to cold temperatures, diesel fuel is prone to “waxing” or “gelling,” meaning the liquid begins to solidify into a thick, viscous texture. When this happens, the fuel will start to appear opaque and cloudy and it won’t have the same fluidity. As a result of this thickening, it’s common for fuel filters and engine injectors to become clogged. Gelled fuel can also build up within a vehicle’s fuel lines, eventually causing the engine to shut off.

During the winter, fuel delivery companies provide diesel that’s fortified with special chemical additives to prevent these negative effects. Often called No. 2 fuel, this winterized fuel has a lower freezing point and offers better engine performance when driving in cold climates.

How Does Summer Impact Diesel Fuel?

As a result, it’s perfectly safe to use standard diesel fuel in your vehicle without risking harm to your engine. However, because summer is also the season to take vacations, consider using premium diesel fuel if you have a long road trip planned. With its higher cetane concentration, premium fuel burns more efficiently, leading to better mileage per gallon.
