Stay with OE specification
An oil filter is more than dimensions: micron rating, bypass valve, and anti-drainback membrane all matter. Cross-reference catalogs are a starting point; the decision belongs on the datasheet.

Long-Haul Truck Oil Filter Program
In fleet operations the oil filter program isn't a cost line; it's an investment that directly controls engine life. Three principles cover it.
Don't forget the primary fuel filter
Common-rail diesels are sensitive to the smallest fuel contamination. Inspect the fuel/water separator (primary) and the secondary filter at every oil service.
Tie intervals to analysis
Oil analysis (TBN, iron, silicon) tells you the actual interval. The OEM number is a starting point; field data is the decision point.
