Usage Fluid/Lubricant
Engine Oil
The engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard can be identified as
synthetic, and should also be
identified with the American
Petroleum Institute (API) Certified
for Gasoline Engines starburst
symbol. However, not all synthetic
API oils with the starburst symbol
will meet this GM standard.
Look for and use only oil that
meets GM Standard GM4718M.
For the proper viscosity, see
Engine Oil on page 5-13.
