We have tried Fleetguards with no change in the past. Even tried their extended service filter with the same issues. This truck had issues with the factory crank. There is an issue somewhere.

As a side note, low oil pressure issues aside ...

I can only imagine that your also NOT seeing what people were trying to say about after-garbage branded oil filters as well.

You are likely missing some key related information along the lines of using after-branded filters, and YES it is VERY VERY important to know about.

Not all filters are created equal, and some brands have been NOTORIOUS for destroying ISX's (or clogging cross-channels, etc. ) due to poor o-ring designs in the filter itself. Some of the top brands are even guilty of this ... and there are a lot of chineesuium fakes out there that have gotten into the market, claiming to be genuine.. but have the older known-to-destroy engine designs in them.

Here is some related info on this subject...
