Going to a smaller micron fuel filter?

[pisymbol]

A couple of buddies of mine who work on diesels say its in your best interest to go to a smaller fuel filter on any diesel. Typically the standard filter is around 20 microns, they are talking about getting something that is around 5 microns. The downside is you have to change it a bit more often.

Any thoughts?

These trucks have a primary and a secondary. The primary filters it to 20 microns and the secondary goes down to either 5 or 2 can'r remember. You're good to go. I'd still change em out every 10,000 miles though. The manual recommends 22,000, but that's just crazy talk right there.

does the 6.7 have a fuel filter warning like chevies or is it strictly by mileage

The problem with small micron is in cold climates you really need to be sure to run anti-gel and run the best fuel quality you can or it will plug the filter extemely fast.
And no there is not a filter light but there is a low pressure sensor that does the same thing.
