2009 HONDA RIDGELINE octane

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration.
Do not change the oil until the
scheduled maintenance time.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not tow a trailer.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Your vehicle is designed to operate
on unleaded gasoline with a pump
octane number of 87 or higher. Use
of a lower octane gasoline can cause
a persistent, heavy metallic rapping
noise that can lead to engine damage.
We recommended using a quality
gasoline containing detergent
additives that help prevent fuel
system and engine deposits.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contactyour authorized dealer f or service.
Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10% ethanol by
volume and up to 15% MTBE by
volume. Do not use gasoline
containing methanol.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Premium f uel is recommended when
towing in certain conditions (see
page ).
