Erubin,

Try Power Service "Diesel Kleen" first. Even though the DFS is "supposed" to deal better with water and winterizing issues, my experiments have shown me that, of the two, DK actually does a better all-around job of cleaning, removing water and winterizing. It will also increase cetane.

One thing you might try that's an easy fix right now, is replace the plastic pre-filter. It's inline, easy to get to and replace. The fuel might have a "winterizing" additive that can kill algae and clean the tank and you might be dumping some "goo" out.

Easy try and most engines need the filters replaced anyway. For $2-3, it's good preventative maint and may help solve a running issue right now, especially if there's some high-speed power loss.

Good luck!
