Understanding why diesel is affected by cold flow issues in winter

When the weather turns cold and the temperature falls, the properties of diesel could potentially cause problems with how a vehicle’s engine operates. This is all because of the chemistry of middle distillate fuels.

Typical diesel fuel is normally comprised of up to 30 percent paraffins. These are the least soluble constituents in diesel. When the temperature of the fuel is lowered below its Cloud Point these paraffins will precipitate as wax crystals. This in turn can give rise to operability issues as the fuel starts to thicken. It is this build-up of wax in the fuel system that can block fuel lines and filters.
