if we factor in the filter used, you can extend your oil change interval to 10,000 to 12,000 KM easily by simply using a high quality, heavy duty oil filter. filtration is the key to extended oil change interval. whether you are using mineral based or fs oils. diesel rigs tend to operate dirtier than petrol rigs so tendency is shorter interval for diesel rigs.
