Currently, I am thinking that I would like to put as much fuel in the tank as I expect to use in 3 months. I'm not worried about condensation but fuel freshness.
Dhays,

Regarding freshness... is there a real issue? Does diesel degrade over time? I've heard that is does not... to any significant amount. I've got a friend that has been using the same diesel over the past 10 years when I last topped off and no issue. He just doesn't travel far.

As for a biocide, suspect that might keep the filter cleaner?

I'm not in any camp on topping off or not... I just don't ever want to run out at the wrong time, so will fill accordingly, and see little reason to make a partial fill.
