2008 HONDA RIDGELINE engine oil

Your vehicle’s exhaust contains
carbon monoxide gas. Carbon
monoxide should not enter the
vehicle in normal driving if you
maintain your vehicle properly and
f ollow the inf ormation on this page.High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
vehicle out of the garage.
Have the exhaust system inspected
f or leaks whenever:
The vehicle is raised f or an oil
change.
You notice a change in the sound
of the exhaust.
The vehicle was in an accident
that may have damaged the
underside. With a truck cap installed and the
back window open, engine exhaust
may enter the vehicle and cause a
hazardous condition. Keep the back
window tightly closed whenever you
drive with a truck cap installed.
If you must sit in your parked vehicle
with the engine running, even in an
unconf ined area, adjust the heating
and cooling system/climate control
system as f ollows:
Select the f resh air mode.
Select the mode.
Turn the f an on high speed.
Set the temperature control to a
comfortable setting.

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 ).

inf ormation, please ref er to your

Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.Remove the dipstick (orange loop).
Wipe of f the dipstick with a clean
cloth or paper towel.
Insert the dipstick all the way back
into its hole. Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page . Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
on page f or
inf ormation on adding the proper
coolant.

The f ollowing f actors can lower your
vehicle’s f uel economy:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
aremoreefficientwhenwarmed
up)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see on page ).
For example: An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption. In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption. Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible. Idling
results in 0 miles per gallon.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one. The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
