Lubricating oil recommendations
Approved lubricating oil
Esso Estor HPC 40
Caution: To use a lubricating oil other than that specified, it is essential that Perkins Engines Company
Limited, Stafford, is consulted, failure to do so could affect the engine warranty.
Oil and filter change programme
The lubricating oil and filter life is governed by the engine load and gas quality. To determine the optimum oil
and filter change period after the engine has been commissioned, use the oil analysis programme which
follows.
Initiating an oil analysis programme
Caution: The oil sample must be taken from the mean level in the engine sump, never from the sump drain
plug.
Note: During the engine’s initial 500 hour running period, oil analysis will show higher levels of iron and copper
than the acceptable contamination parameters, marked (*) in the list below. As the engine continues to run the
levels will drop within the specified parameters.
Every 250 hours after the first 500 hour oil and filter change the oil should be analysed.
At 750 hours by comparing the oil analysis results a contamination trend can be established, allowing each
individual operator to develop an oil and filter change policy for the operating conditions of their engine.
Caution: Irrespective of condition the lubricating oil and filters MUST be changed at 2000 hours.
