Oil and oil filter cartridge are first changed at the 1,500 mile inspection. Subsequent oil and filter changes should be made at 7,500 mile intervals or at least twice a year.

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 operations at freezing temperatures require oil changes more frequently (every three month).

* * EGR valve to be cleaned at 15,000 & 45,000 mile service intervals and is replaced at 30,000 miles
1) For cars used for hard driving, or in hilly terrain etc. preventive service including oil change should be carried out every 30,000 miles.
