2.3.8 Oil Change

WARNING
A hot engine or engine oil can be dangerous.
Serious burns can result from contact with a
hot engine or oil. Take precautions when
draining the oil. Wear gloves or let the engine
cool down before draining.
WARNING
When draining the oil, use the proper tools
and keep away as far as possible. Raise the
elbow so the forearm is parallel to the ground
to prevent oil running down the arm, causing
burns.
CAUTION
Always dispose of all lubricants (motor oil,
coolant, gear box oils, etc) and filters
according to Federal or local regulations.
Used oil disposed of in nature or waterways
contaminates our drinking water and kills
wildlife.
WARNING
Prolonged contact with used engine oil may be
harmful. Use rubber gloves when handling
used oil. Wash skin thoroughly if it comes in
contact with used oil.
It is important to drain as much oil as possible.
Try to change oil immediately after driving, when
the oil is warm. Always replace the oil filters
when changing the oil.

WARNING
Hot oil can cause severe burns. DO NOT
allow hot oil to contact the skin. When
changing oil, wear protective gloves.
CAUTION
Volvo-branded oil filters are designed to
provide the proper level of filtration and
protection for Volvo engines. Filters that do
not meet the same stringent requirements
may cause unsatisfactory results.
