B Series engines have been designed for reduced maintenance with plateau-honed cylinders, an innovative ring pack design and edge-molded gaskets for significantly reduced oil consumption. With Cummins B Series, little or no top-off oil should be needed. Oil change intervals can be extended up to 500 hours. And the B Series uses durable, reliable rotary fuel pumps for strong performance in every kind of weather condition.
