5.9L/6.7L Cummins Fleetguard Stratapore/Venturi Extended Life Oil Filter

Introducing the Fleetguard LF9028:

It has a standard full flow oil filter, in addition to a bypass style (sub2-micron) filter in one housing. 
Basically, you could say it is the equivalent of a "bypass oil filtration system, without the extra hoses".

Here is a exerpt from the above link:
The Venturi delivers on extended maintenance intervals, better oil condition and improved engine life.
■ Severe Duty Australian Road Trains prove you can SAFELY extend oil drain intervals up to 2x longer for a maximum of 75,000 miles (121,000 km)*
■ REAL™ World results prove Venturi reduces environmental waste and oil / filter consumption by SAFELY extending oil drain intervals.
■ REAL World results prove Venturi reduces costs by maintaining better oil condition and maximizing engine life.

This filter is generally marketed as an Agricultural Kubota filter, but it will fit in place of the standard oil filter on any 1989-2018 Dodge 3.9L, 5.9L or 6.7L Cummins engine.

Customers have reported that they are able to use their oil and filter for a MUCH longer interval. They report that their oil stays cleaner much longer (doesn't get nearly as dark/black). Some customers change the oil 2-3 times without changing this filter.*
