Jeep Wrangler: NORMAL OPERATION — DIESEL ENGINE / Engine Idling
Avoid prolonged idling, long periods of idling
may be harmful to your engine because
combustion chamber temperatures can drop so
low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings, cylinder head
valves, and injector nozzles. Also, the unburned
fuel can enter the crankcase, diluting the oil
and causing rapid wear to the engine.
Operation in ambient temperature below 32°F (0°C) may require special
considerations. The following charts suggest these options:
Fuel Operating Range
NOTE:
Use “Ultra Low Sulfur Diesel Fuels (ULSD)” ONLY...
After full load operation, idle the engine for a
few minutes before shutting it down. This idle
period will allow the lubricating oil and coolant
to carry excess heat away from the
turbocharger...
