1 The lubricating oil and lubricating oil filter interval is determined by the sulfur content of the fuel used, the
lubricating oil type used, and the engine rating. See the Oil Drain Intervals in this section.
2 Antifreeze check interval is every oil change or 500 hours or 6 months, whichever occurs first. The operator must
use a heavy-duty year-round antifreeze that meets the chemical composition of ASTM D6210. The antifreeze
change interval is 2 years or 2000 hours, whichever occurs first. Antifreeze is essential for freeze, overheat, and
corrosion protection.
