Use quantity of fuel used, distance (odometer) interval or service hours, whichever occurs first.1Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumed. However, Caterpillar recognizes that the distance (odometer) interval is most commonly used to schedule maintenance for on-highway vehicles. Distance intervals are based on a typical over-the-road truck application. For other applications use hours or fuel intervals to determine and schedule maintenance.Daily
