2006 LEXUS RX330 Specifications

ENGINE
551
FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller
fuel tank opening. The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle on pumps with
leaded gas will not.
At a minimum, the gasoline you use should meet the
specifications of ASTM D4814 in the U.S.A. and CGSB
3.5−M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will
cause the threeway catalytic converter to lose its
effectiveness and the emission control system to
function improperly. Also, this can increase
maintenance costs.
Octane rating
Premium unleaded gasoline with an Octane Rating of 91
(Research Octane Number 96) or higher required for
optimum e ngine performance. However, if such premium
type cannot be obtained, you may use unleaded gasoline
with an Octane Rating as low as 87 (Research Octane
Number 91).
Use of unleaded fuel with an Octane Rating or Research
Octane Number lower than stated above will cause persistent
heavy knocking. If it is severe, this will lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when using the
recommended fuel, or if you hear steady knocking while
holding a steady speed on level roads, consult your Lexus
dealer.
However, occasionally, you may notice light knocking for a
short time while accelerating or driving up hills. This is normal
and there is no need for concern.
Gasoline containing detergent additives
Lexus recommends the use of gasoline that contains
detergent additives to avoid buildup of engine deposits.
However, all gasoline sold in the U.S. contains detergent
additives to keep clean and/or clean intake systems.

ENGINE
557
If the oil level is below or only slightly above the low mark,
add engine oil of the same type as already in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to
raise the level between low mark and full mark on the dipstick
is indicated as follows:
1.5 L (1.6 qt., 1.3 Imp. qt.)
For the engine oil capacity, see “Specifications” on page 548.
When the level reaches within the correct range, return the filler
cap and turn the cap clockwise until you hear a click.
NOTICE
 Be careful not to spill engine oil on the vehicle
components.
 Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstick once again after
adding the oil.

a layer of rubber −coated parallel cords. Cords
mean the strands forming the plies in the tire.

“RADIAL” on the sidewall. A tire not marked with
“RADIAL” is a bias−ply tire.
6“TUBELESS” or “TUBE TYPE”: A tubeless tire
does not have a tube inside the tire and air is
directly filled in the tire. A tube type tire has a
tube inside the tire and the tube maintains the
air pressure.
7Load limit at maximum cold tire inflation
pressure: For details, see “Checking and
replacing tires” on page 585.
8Maximum cold tire inflation pressure: This
means the pressure to which a tire may be
inflated. For details about recommended cold tire
inflation pressure, see “Specifications” on page
564.
9Uniform tire quality grading — For details, see
“Uniform tire quality grading” that follows.
