Minimum maintenance has been built into every QSK19 engine. One example is the single-piece ferrous cast ductile iron pistons that provide exceptional durability and cut oil consumption by 20%. Cummins QSK19 engines require an oil change every 250 hours.
Extended Service Options: oil service costs can be significantly reduced and oil drains extended up to 1,000 hours with Cummins Eliminator™ centrigual filtration system and to even longer with Centinel™ oil replacement service.
