SITUATION:
WINTER CHANGE OF OIL AT PDI
Oil viscosity and battery condition have a significant effect upon engine cranking speed, particularly in cold temperatures. 5W/30 or 5W/40 engine oil
and the starting procedure specified in TIB 12/07/94/US will ensure that the best cranking speed and lubrication characteristics are achieved in extremely
cold weather.
RESOLUTION:
PDI OIL CHANGE BETWEEN 1 OCTOBER AND 30 MARCH
NOTE:
The need for a change to lower viscosity oil at PDI is limited to the winter months. A PDI oil change to 5W/30 or 5W/40 oil is not warranted at other
times of the year and should not be performed.
To ensure that proper viscosity oil is used during warm weather driving, oil changes to 5W/30 or 5W/40 engine oil at PDI may only be performed when
cold weather driving is the expected condition during break-in. Land Rover has determined that the period between October 1st and March 30th is the
