Going to a smaller micron fuel filter?

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.

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.
