Changing the Engine Oil and
Replacing the Engine Oil Filter
Element
The engine oil on a new engine becomes
contaminated from the initial break-in of
internal parts. It is very important that the
initial oil replacement is performed as
scheduled.
It is easiest and most effective to drain the
engine oil after operation while the engine is
still warm. WARNING! If you must drain
the engine oil while it is still hot, stay
clear of the hot engine oil to avoid being
burned. ALWAYS wear eye protection.
