I was just headed out to adjust the valves, and change filters on the 84 300TDT. Figured I would ask the forum what they do to prepair their car.

More specifically do you change your main fuel filter just before winter, or only at the 30,000 mile interval as MB suggests? My filters have about 10,000 or so on them, so may be that is being wasteful? I guess I am wondering about water build up. My Dodge has a drain plug on the filter, to remove water in the fuel. Not so on the TDT, thus the impulse to change it
