Engine Oil and Filter - Change
Ensure that the container for the sample is clean and
dry. Also ensure that the container for the sample is
clearly labelled.
To ensure that the sample is representative of the
oil in the crankcase, obtain a warm, well mixed oil
sample.
To avoid contamination of the oil samples, the tools
and the supplies that are used for obtaining oil
samples must be clean.
The sample can be checked for the following: the
quality of the oil, the existence of any coolant in the
oil, the existence of any ferrous metal particles in
the oil, and the existence of any nonferrous metal
particles in the oil.

Engine Oil and Filter - Change
Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
Do not drain the oil when the engine is cold. As the oil
cools, suspended waste particles settle on the bottom
of the oil pan. The waste particles are not removed
with the draining cold oil. Drain the crankcase with
the engine stopped. Drain the crankcase with the
oil warm. This draining method allows the waste
particles that are suspended in the oil to be drained
properly.
Failure to follow this recommended procedure will
cause the waste particles to be recirculated through
the engine lubrication system with the new oil.
Drain the Engine Oil
After the engine has been run at the normal operating
temperature, stop the engine. Use one of the
following methods to drain the engine crankcase oil:
•
If the engine is equipped with a drain valve, turn the
drain valve knob counterclockwise in order to drain
the oil. After the oil has drained, turn the drain valve
knob clockwise in order to close the drain valve.
•
If the engine is not equipped with a drain valve,
remove the oil drain plug in order to allow the oil to
drain. Discard the washer. If the engine is equipped
with a shallow sump, remove the bottom oil drain
plugs from both ends of the oil pan.
After the oil has drained, the oil drain plug should be
cleaned. Install a new washer to the oil drain plug.
Reinstall the oil drain plug.
