238 STARTING AND OPERATING

sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.

FUEL REQUIREMENTS

The 3.7L/4.7L engines are designed to
meet all emissions regulations and provide
excellent fuel economy and performance
when using high quality unleaded "regu-
lar" gasoline having an octane rating of 87.
The routine use of premium gasoline is not
recommended. Under normal conditions the use of pre-
mium fuel will not provide a benefit over high quality
regular gasoline and in some circumstances may result in
poorer performance.
The 4.7 HO engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high quality unleaded gasoline hav-
ing an octane range of 87 to 91. The manu-
facturer recommends the use of 91 octane
for optimum performance.
