Fuel Requirements - Gasoline Engine; 2.0L And 2.4L Engine; Methanol; Ethanol - Jeep Compass Operating Information Manual

**Use only your authorized dealer recom-
mended lug nuts/bolts and clean or remove any
dirt or oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice.
Torque Patterns
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts fully until the
vehicle has been lowered. Failure to follow
this warning may result in personal injury.
FUEL REQUIREMENTS –
GASOLINE ENGINE

2.0L And 2.4L Engine

All gasoline engines are designed to meet all
emissions regulations and provide excellent fuel
economy and performance when using high
quality unleaded gasoline with a minimum re-
search octane rating (RON) of 91.
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.
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives may help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
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.

Methanol

(Methyl) is used in a variety of concentrations
when blended with unleaded gasoline. You may
find fuels containing 3% or more methanol along
with other alcohols called cosolvents. Problems
that result from using methanol/gasoline are not
the responsibility of the manufacturer. While
MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
WARNING!
Do not use gasolines containing Methanol.
Use of these blends may result in starting
and drivability problems and may damage
critical fuel system components.

Ethanol

The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 15% limit and/or of receiving fuel
with abnormal properties. It should also be
noted that an increase in fuel consumption
should be expected when using ethanol-
blended fuels, due to the lower energy content
of ethanol. Problems that result from using
