xaliber submitted a new mod: Realistic Fuel Cost - The farther you go, the costlier the fuel! Read more about this mod...
It no longer works in the 1.4.1 version as it breaks the navigation console. Too bad because I liked it in pre 1.4 Can you update your mod to last version ? I prefered refilling my fuel regularly instead of only needing 90 per travel... Overall I find it a bit too much expensive for a condor ship, even with a mechanic aboard.
