228 MAINTAINING YOUR VEHICLE Dusty Conditions Driving through dust-laden air increases the problems of keeping abrasive materials out of the engine. Under these conditions, special attention should be given to the engine air cleaner and the crankcase inlet air cleaner. The crankcase ventilation system should also be checked periodically. Make sure that these units are always clean. This will tend to reduce to a minimum the amount of abrasive material that may enter the engine. Engine Oil Selection For best performance and maximum protection under all types of operating conditions, the manufacture only recommends engine oils that are API certified and meet the requirements of DaimlerChrysler Material Standard MS-6395. Use Mopar or an equivalent oil meeting the specification MS-6395. American Petroleum Institute (API) Oil Identification Symbol There is a symbol to aid you in selecting the proper engine oil. This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacture only recommends API Certified engine oils that meet the requirements of DaimlerChrysler Material Standard MS-6395. Use Mopar or an equivalent oil meeting the specification MS-6395. Engine Oil Viscosity Chart The proper SAE viscosity grade of engine oil should be selected based on the following recommendation and be within the operating temperature shown in the recommended SAE viscosity chart. • SAE 5W-30 is the oil recommended in trucks equipped with a 3.7L/4.7L engine, for optimum fuel economy. • Synthetic engine oils may be used provided that the oil quality requirements described above are met and the recommended maintenance intervals for oil and filter changes are followed.
