CN101 - Maintenance
Engine Oil Consumption (TB 1549)
The following instructions should be implemented for the Deutz engines fitted to the Johnston
CN101.
The instructions apply during the first 500 to 700 operating hours and are intended to prevent high
oil consumption:
• Higher than usual oil consumption during the first 500 to 700 operating hours of the running-in
period is quite normal.
• In general and especially during the running-in period the engine should not be left to idle for
long periods.
• Only use the oil grade recommended in the operator manual.
Do not use a lower grade oil.
Using a lower grade oil will increase oil consumption.
• The oil level may be checked with the engine hot or cold with the engine switched off. If the
engine has been running it should be switched off for minimum of 5 minutes prior to checking
the level to allow the oil to settle.
If you want to compare oil levels ensure that the oil levels to be compared are checked under
similar conditions.
• When filling, only fill up to the halfway mark on the dipstick. If you fill to the upper mark, the
engine will use the excess oil until the level drops to the halfway mark. Often this is declared as
the normal oil consumption of the engine but this is not in effect the case.
• If engine oil consumption is exceptionally high despite implementation of the running-in
instructions, you should inform your local Johnston representative. You will also be asked to
record the consumption data over a period of 100 hours running time. You should record the oil
consumption and the fuel consumption for comparison.
The limit value for the maximum specific lubricant consumption is 0.75 % (max.) of fuel
consumption.
