Donaldson DBL7900 Blue® Oil Filter | Premium Synthetic Oil Filter for Cummins X15 & ISX Engines

Donaldson DBL7900 Blue® Oil Filter for Cummins X15 & ISX Engines

The Donaldson DBL7900 Blue® Oil Filter is a premium synthetic media full-flow lube filter engineered for extended service intervals and maximum engine protection in today's heavy-duty diesel engines. Designed specifically for Cummins X15 and ISX applications, the DBL7900 utilizes Donaldson's advanced Synteq™ filtration media to provide superior contaminant removal, increased dirt-holding capacity, and exceptional engine protection.

Unlike conventional cellulose oil filters, the Donaldson Blue® DBL7900 removes more than 90% of contaminants 10 microns and larger while providing twice the contaminant-holding capacity of standard filters. This allows fleets and owner-operators to maximize maintenance intervals while protecting critical engine components from wear-causing contaminants. :contentReference[oaicite:0]{index=0}
