FUEL REQUIREMENTS

6.4L Engine

The 6.4L 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 experi-

ence these symptoms, try another brand of gasoline

before considering service for the vehicle.

Over 40 auto manufacturers worldwide have issued and

endorsed consistent gasoline specifications (the World-

wide Fuel Charter, WWFC) which define fuel properties

necessary to deliver enhanced emissions, performance,

and durability for your vehicle. The manufacturer recom-

mends the use of gasolines that meet the WWFC speci-

fications if they are available.

Reformulated Gasoline

Many areas of the country require the use of cleaner

burning gasoline referred to as “Reformulated Gasoline”.

Reformulated gasolines contain oxygenates and are spe-

cifically blended to reduce vehicle emissions and im-

prove air quality.

The manufacturer supports the use of reformulated gaso-

lines. Properly blended reformulated gasolines will pro-

vide excellent performance and durability of engine and

fuel system components.
