1. INTRODUCTION
The useful life of a lube oil charge depends on many and varied factors. Determinants are the oil working time,
engine oil consumption, type and grade of fuel, volume of circulating oil, lubricant quality, engine condition, oil
temperature, etc.
Oil change frequencies should not exceed the recommendations (due to the degradation of the additives) unless
a careful oil analysis programme is previously implemented. But, even in this event, remember that lab analysis
are normally intended to detect troubles with the engine, rather than predicting the exact time additives will fail. It
is therefore important to inspect the engine before making a decision of modifying the oil change intervals.
Accordingly, when determining the oil life, it is necessary to make a series of analysis in order to obtain
information on the oil performance tendency or specific details on its evolution.
Changing the oil charge must be made either in accordance with the maintenance instructions for each type of
engine and application or when the values of the tested parameters have reached their maximum permissible
limits as specified in the oil maintenance instructions in respect of each application, or else when the operating
conditions require that oil be changed before the limit values are reached.
Check the sump oil level daily to detect possible contamination by water or fuel and to make yourself an idea of
the oil condition.
If this visual inspection reveals that oil on the dipstick has lost consistency, flows quickly, is muddy, milky or thick,
then oil must be changed.
Changing the oil of an engine is not limited to draining oil from the sump and cooler, but also implies changing the
oil filters.

2. OIL CHANGE PROCEDURE

The oil change procedure is identical for all types of engines and must always be performed after stopping the
engine, with the oil still hot, since in this state, oil drains better and faster.
Procedure:
1. Drain the sump. To do so, open the oil sump drain plug or use a draining pump.
If the engine incorporates a the pre-lubricating pump, you can use it as a draining pump.
