ENGINE MAINTENANCE - Engine Lubrication and Filter Intervals Engine Oil Capacity and Acceptable Pressures (continued) 2 Engine Lubrication and Filter Intervals NOTE for the oil change and oil filter change interval. Idle time must be factored into calcu- lating average vehicle speed. If the average vehicle speed/mph is unknown and the vehicle is not equipped with an hour meter: Oil change intervals for normal and severe duty applications. See the following table to determine the maximum recommended oil change and oil filter change intervals in miles (kilometers)/ hours or months, whichever comes first.
The intervals are based on the vehicles average speed/miles per hour (mph) (Includes idle time). Locate your vehicles average vehicle speed/mph in the first column to determine the oil change/filter change interval to use. If the vehicle is equipped with an hour meter, it is acceptable to use the engine hours listed 1. See the "Typical Application(s)" column. Use the lowest interval listed for your application. 2. Connect an electronic service tool. The electronic service tool can provide the average vehicle speed recorded by the engine control module (ECM). This can be done at a PACCAR Authorized Repair Location.
Replace the fuel filters (pressure and suction side) at the same interval as the oil and oil filter are changed. 46 Y53-1185-1E1 (04/16/18) Lubricating oil filter capacity 4 qts.
