Fuel Temperature (Degrees Fahrenheit) – LUZ

Description

Temperature of the fuel reported in degrees Fahrenheit.

Usage Notes

The temperature of the fuel indicates how much fuel is injected into the engine cycle. If the fuel is warm and therefore less dense, more fuel is injected, while colder temperatures (more dense) require less fuel.

As temperatures drop, the wax in diesel fuel can solidify. At 32 degrees Fahrenheit the wax will start to crystallize and will eventually gel at 10-15 degrees Fahrenheit. The gelling that occurs in cold weather can clog the fuel filter and tank, which may result in replacement. To help prevent the fuel filter from clogging, GM vehicles are equipped with a fuel heating system.
