Lubricating oil
With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low-
sulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable
to employ the CF, CD or CE lubricating oil with a high total base number. If the CF-4 or CG-4 lubricating oil is used
with a high-sulfur fuel, change the lubricating oil at shorter intervals.
ALubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.
