FUEL REQUIREMENTS

6.4L Engine

The 6.4L engine is designed to meet all
emissions regulations and provide excellent
fuel economy and performance when using
high-quality premium unleaded gasoline

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.
