oil viscosity PONTIAC GTO 2006 Owners Manual

What Kind of Engine Oil to Use
Look for two things:
·GM4718M
Your vehicle's engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this
standard may be identi®ed as synthetic. However,
not all
syntheticoils will meet this GM standard.
You should look for and use only an oil that meets
GM Standard GM4718M.
Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
·SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.
Oils meeting these
requirements should also
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certi®ed by the American
Petroleum Institute (API).
You should look for this on the oil container, and use
onlythose oils that are identi®ed as meeting GM
Standard GM4718M and have the starburst symbol on
the front of the oil container.
