 Paccar PX-7 Engine Operator's Manual | The primary PACCAR recommendation is for the use of 15W-40 multigrade lubricating oil for normal operation at ambient temperatures above -15°C [5°F]. The use of multigrade oil reduces deposit formation, improves engine cranking in low temperature conditions and increases engine durability by maintaining lubrication during high temperature operating conditions. Since multigrade oils have been shown to provide approximately 30 percent lower oil consumption compared with monograde oils, it is important to use multigrade oils to be certain the engine will meet applicable emissions requirements. Use of "synthetic engine oils" (those made with API group 3 or group 4 base stocks) is permitted subject to the same performance and viscosity limitations of petroleum (mineral) based engine oils. The same oil change intervals must be applied to synthetic oils that are applied to petroleum (mineral) based engine oils. |

PACCAR PX-7 OIL CHANGE INTERVAL
PACCAR bases its oil drain specifications on duty cycle and oil contamination. This contamination occurs in all engines at varying rates regardless of design. Maintaining the correct oil and filter change interval is a vital factor in preserving the integrity of an engine. Filters must be changed when the oil is changed.
