This engine is designed to meet all emis-

sions regulations and provide excellent

fuel economy and performance when us-

ing high-quality unleaded "regular" gaso-

line having an octane rating of 87.

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.
