PUMP GP-GEAR 2316587 - Caterpillar

There are many applications of medium duty truck engines. It is important to understand the operation of your vehicle. Use the fuel consumption, service hours, or calendar time, whichever occurs first, in order to determine the maintenance intervals. Engines which operate in severe operating conditions may require more frequent maintenance.Instructions for the Table
Determine your type of vehicle application. Locate the column which lists your type of vehicle application.
Determine your available oil in liters or quarts. The oil quantity equals the sum of the capacities of the oil sump and the oil filter. Locate the row which lists your available oil.
The intersection of the column and the row lists the maximum permissible number of kilometers or miles between oil change intervals. Example
The vehicle application is a light duty commercial application. The oil capacity of the engine is 21 L (22 qt) and the oil capacity of the auxiliary oil filter is 10 L (10 qt). With CatS O S Oil Analysis verification, the maximum permissible oil change interval is 30900 kilometers (19200 miles).For more information on optimizing oil change intervals, see your Cat dealer.
