Fuel System Requirements The high performance V-8 engine in your Corvette is designed to operate efficiently on premium type gasolines. See page 43 for
octane requirements. Use of regular grade gasolines in higher
performance engines may result in potentially dangerous engine
detonation.

FILLER

in severe detonation. Should this occur consult an authorized Chevro­
let
Dealer so that adjustments can be made to eliminate this detona­
tion or reduce it to a safe level.
Lift tip the Corvette emblem on the rear deck to reach the fuel filler cap. II the cap is lost be sure to replace it with a vented cap.
In
all cases excessive engine detonation, or knocking, should be
avoided in order to prevent possible eng ine damage .
