Chev 2500HD Oil and Fuel Filter

[MartyQ]

Question for the group. For the past several years have been putting less 3000 miles on my 2003 Chev 2500HD 6.6L diesel each year.

How often should I be changing the fuel filter?

You should change your oil and filter yearly regardless of miles driven in your case. As for your fuel filter I would change this yearly also and put in a good diesel fuel treatment from Power Service that will treat your fuel. This is to keep the fuel from absorbing water over time.
