NOTE
Engine Oil
• Oil used in the engine should have an American Petroleum Institute (API) service classification and Proper SAE
Engine OIl according to the ambient temperatures as shown above.
• With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low-
fulfur fuel on on-road vehicle engines. When an off-orad 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.
• Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.
