NEVER use starting fluid (i.e. ether) to assist in
starting engine. Sever engine damage will result.
Engine Oil Requirements
1. 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 for 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.
API service classification: above CD grade.
Ambient temperature: below 35°C (95°F).
Lubricating oil recommended when a low-sulfur or high-
sulfur fuel is employed.
