2006 HONDA RIDGELINE oil viscosity

Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.Honda Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection. Make
sure the API Certif ication Seal says
‘‘For Gasoline Engines.’’
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill any. Clean up any
spill immediately. Spilled oil could
damage components in the engine
compartment. Install the engine oil
f ill cap, and tighten it securely. Wait
a f ew minutes, and recheck the oil
level (see page ). Do not f ill
above the upper mark; you could
damage the engine. The oil viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your vehicle to
improve cold weather starting and
f uel economy.

The transf er assembly should be
drained and ref illed with new f luid
when this service is indicated by a
maintenance message on the
inf ormation display.
Always use Hypoid gear oil GL4 or
GL5 with a viscosity of SAE 90 or 80-
90W, and have your dealer replace
the transf er assembly f luid.Check the brake f luid level in the
reservoir monthly.
Replace the brake f luid according to
the time recommendation in the
maintenance minder schedule.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage. Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible. Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
