2018 JEEP COMPASS fuel additives

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 hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.

Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 10% ethanol. Purchasing your fuel from
a reputable supplier may reduce the risk of
exceeding this 10% limit and/or of receiving
fuel with abnormal properties.
CAUTION!
Use of fuel with Ethanol content higher
than 10% may result in engine malfunc-
tion, starting and operating difficulties,
and materials degradation. These adverse
effects could result in permanent damage
to your vehicle.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
• The use of leaded gasoline is prohibited
by law. Using leaded gasoline can impair
CAUTION!
engine performance and damage the
emissions control system.
• An out-of-tune engine or certain fuel or
ignition malfunctions can cause the
catalytic converter to overheat. If you
notice a pungent burning odor or some
light smoke, your engine may be out of
tune or malfunctioning and may require
immediate service. Contact an autho-
rized dealer for service assistance.
• The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of metha-
nol. Fuel system damage or vehicle per-
formance problems resulting from the
use of such fuels or additives is not the
responsibility of the manufacturer and
may void or not be covered under the
New Vehicle Limited Warranty.
NOTE:
Intentional tampering with the emissions
control system can result in civil penalties
being assessed against you.
