NOTE
With emission controlsnow in effect, theCG--4
or CH--4 / CI lubricating oils have been devel-
oped for use of a low--sulfur fuel on--road ve-
hicles engines. When an off--road vehicle en-
gine runs on a high--sulfur fuel, it isadvisable to
employ the CH--4 / CI lubricating oil with a high
total base number. If the CG--4 lubricating oilis
usedwithahigh sulfurfuel,changethelubricat-
ing oil at shorter intervals.
Lubricating oil recommended when a low--sulfur or
