FUEL REQUIREMENTS

8.4L Engine

The 8.4L engine is designed to meet all

emissions regulations and provide excel-

lent fuel economy and performance when

using high-quality premium unleaded

gasoline with an octane rating of 91 or

higher.

Light spark knock at low engine speeds is not harmful to

your engine. However, continued heavy spark knock at

high speeds can cause damage and immediate service is

required.

Poor quality gasoline can cause problems such as hard

starting, stalling, and hesitations. If you experience these

symptoms, try another brand of “premium” gasoline

before considering service for the vehicle.

Over 40 automobile manufacturers around the world

have issued and endorsed consistent gasoline specifica-

tions (the World Wide Fuel Charter, WWFC) which

define fuel properties necessary to deliver enhanced

emissions, engine performance, and durability for your

vehicle. The manufacturer recommends the use of gaso-

lines that meet the WWFC specifications if they are

available.
