Fuel Questions

My 95 xj is only really driven on weekends (i have a company truck during the week). Thus my gas will usually last about a full month. My concern is rust and condensation developing while my rig just sits there. Do you guys think i should try to keep the tank full all the time?? Or is it going to be ok to just leave it and refill when needed??

Your opinions please.

Thanks!!

Full tank = no place for moisture to collect.

Keep it fairly full -- at least a half tank, and preferably not below 3/4 when put up for rest. And periodically dump in a can of Dry Gas, to pick up any moisture and condensation that does get in the fuel.
