What Kind Of Engine Oil To Use - Chevrolet 2005 SSR Pickup Owner's 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 identified as synthetic. However,
not all synthetic oils 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.
You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard GM4718M and have the starburst symbol
on the front of the oil container.
Oils meeting these
requirements should
also have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certified by the American
Petroleum Institute (API).
