* Oil and oil filter cartridge are first changed at the 600-1,200 mile (1,000-2,000 km) inspection.

Subsequent oil and filter changes should be made at 7,500 mile (12,500 km) intervals or at least

every sixth month.

However, adverse conditions (like hot ambient temperatures, trailer hauling, hill climbing, driving

long distances at high speeds, extended periods of idling or low speed operation, short trip

operation at freezing temperatures) require oil changes more frequently (every third month).
