When to Add Engine Oil
If the oil is below the indent at
the tip of the dipstick, add at least
one liter/quart of the recommended
oil. This section explains what kind of
oil to use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 11-2.
Notice: Do not add too much oil.
If the engine has so much oil that
the oil level gets above the upper
hole, the engine could be
damaged.
See Engine Compartment Overview
on page 9-6 for the location of
the engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the
way back in when through.
