How Cold Weather Affects Oils, Grease, and DEF Performance

Cold weather changes how fluids behave, and fleets often feel the impact first. As temperatures drop, motor oils thicken, grease becomes less pliable, and DEF can freeze if it is not stored properly. Without the right products and planning, cold weather can lead to harder starts, increased wear, and unexpected downtime.

Engine oil viscosity is critical in winter. Thicker oil moves slower at startup, which increases friction and stress on engine components. Grease can also stiffen, reducing its ability to protect bearings and moving parts. DEF presents another challenge. At lower temperatures it can freeze, interrupting vehicle operation and triggering derates if supply is compromised.

Energie Fuel Group helps fleets stay prepared by providing bulk motor oils, lubricants, and DEF in multiple presentations. Whether your operation needs bulk tanks, totes, drums, or packaged solutions, having the right products on site ensures consistent performance throughout the colder months. Proper storage and reliable delivery reduce last minute scrambling and protect equipment when it matters most.

Cold weather is unavoidable, but fluid related downtime is not. With the right oils, lubricants, and DEF strategy in place, fleets can maintain performance, protect equipment, and keep operations running smoothly all winter long.
