CID) gasoline engine. This engine is designed to
Engine Oils
Engine oils are labeled on the containers with
various API (American Petroleum Institute) desig-
nations of quality. For.gasoline engines, Chevrolet
recommends the use of an oil with the API designation
"SF", either alone or shown with other designations
such as "SF/CC". Oils which are not labeled "SF"
should not be used. Using oils of a quality other than
those recommended for Chevrolet gasoline engines
could cause engine damage,
Viscosity
Engine oil viscosity (thickness) has an affect on fuel
economy. Lower viscosity engine oils can provide bet-
ter fuel economy; however, higher temperature
weather conditions' require higher viscosity engine oils
operate on either unleaded or regular gasoline. It is
equipped with an electronic ignition system which has
no breaker points or condenser.

for heavy or extended expressway driving in summer
