Fuel

Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle, keeps
the engine clean, and maintains
optimum vehicle performance.

Recommended Fuel

Use regular unleaded gasoline with a
posted octane rating of 87 (R+M)/2
or 91 RON or higher. If the octane
rating is less than recommended, an
audible knocking noise, commonly
referred to as spark knock, might be
heard when driving. If this occurs,
use a gasoline with the
recommended rating or higher as
soon as possible. If heavy knocking
is heard when using gasoline with
the recommended rating, the engine
needs service.

Fuel Additives

Gasoline should contain detergent
additives that will help prevent
engine and fuel system deposits
from forming. Clean fuel injectors
and intake valves will allow your
emission control system to work
properly. Some gasoline does not
contain sufficient quantities of
additive to keep fuel injectors and
intake valves clean. To make up for
this lack of detergency, it is
recommended that one bottle of GM
Fuel System Treatment PLUS (GM
part no. 88861011) be added to the
fuel tank at every engine oil change
or every 15000 km, whichever
occurs first. GM Fuel System
Treatment PLUS is the only gasoline
additive recommended by General
Motors. It is available at your
dealer/retailer.
