Lexus GX470 2006 Service Manual page 537

ENGINE
If the oil level is below or only slightly above the low line,
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 line and full line 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 518.
When the level reaches within the correct range, return the filler
cap and turn the cap clockwise until you hear a click.

D Be careful not to spill engine oil on the vehicle
components.

D Check the oil level on the dipstick once again after
adding the oil.
