periods. Sustained heavy d u ty and high speed operation or
and
operation under adverse conditions may require m ore frequent
servicing.
• Replace the oil filter a t th e first oil change, and every
second oil change thereafter. AC oil filters provide
m axim um engine p rotection.
The above recom m endations apply to the first change as
well as subsequent oil changes. The oil change interval for the
Chevrolet engine is based on the use o f SE oils and quality oil
filters. Oil change intervals longer than those listed above will
seriously reduce engine life and may affect C hevrolet's obliga­
tio n under th e provisions o f the New Vehicle W arranty.
A high quality SE oil was installed in the engine at the
factory. It is n o t necessary to change this factory-installed oil
prior to the recom m ended norm al change period. However,
check the oil level m ore frequently during the break-in period
since higher oil consum ption is norm al until the piston rings
becom e sealed.
N O T E : Non-detergent and other low quality oils
are specifically not recommended.
