5. Add the proper type of oil if the level is low.
Always check the level with dipstick before
adding more oil.
CAUTION: Never operate the engine with the oil level
below "L" mark or over "F" mark on dip-
stick.
CHANGE OIL
For a new engine, change oil after the first 5
hours of operation. Change oil every 25 operating
hours thereafter. For an overhauled engine or
those rebuilt with a new shortblock or miniblock,
use straight 30-weight Service Class SF or SG oil
for the first 5 hours of operation. Change the oil
after this initial run-in period. Change oil every 25
hours thereafter. Drain oil while the engine is still
warm from operation. The oil will flow freely and
carry away more impurities. Change oil as follows:
1. Remove the oil drain plug and dipstick. Tilt the
engine slightly towards the drain hole to obtain
better drainage.
2. Reinstall the drain plug. Make sure it is tight-
ened securely.
3. Fill with new oil of the proper type to the "F"
mark on the dipstick. Always check the level
on dipstick before adding more oil. Make sure
the engine is level when filling and checking
oil.
SERVICE AIR CLEANER

paper air cleaner element. Some specifications
are also equipped with an oiled foam precleaner
which surrounds the paper element. Refer to Fig-
ure 3-2.
