FUEL REQUIREMENTS
While operating on gasoline with the required octane
number, hearing a light knocking sound from the
engine is not a cause for concern. However, if the
engine is heard making a heavy knocking sound, see
a dealer immediately. Use of gasoline with a lower
than recommended octane number can cause
engine failure and may void or not be covered by the
New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
