the oil suction hose by removing it from
the oil pump.
After bleeding the air, reconnect the
hose with a locking tie.
Recommended engine oil:

the oil pump hoses for proper routing
and make sure there are no restrictions
in the line.

another oil can seriously damage the
catalytic converter and other engine
