Let's say that I have a fuel tank capacity 4 (tonnes?), how much can I jump with full tank? How much fuel do I use per jump/light year?
Now this is a tricky one.
It's a 'how long is a piece of string?' question.
Ok so I'll have a go.
1. The weight of your ship including cargo affects maximum range. to increase, sell cargo or remove equipment.
2. You FSD has a maximum fuel per jump it can use. In a stock Cobra this is 2 tons.
3. When buying upgrades, the maximum jump range for your ship is show on the right. (I think it has a slight bug, but it does show the max range you can get with the selected upgrade with a full cargo and without (laden/unladen)
4. Oh and FSD also has max weight limit it can jump.
5. Finally, a lot of shorter jumps seem to use less fuel than one big one. The Galaxy Nav system always seem to pick lots of short jumps unless you tell it otherwise.
.
So buying those nice new lasers will reduce your jump range!
More expensive equipment upgrades are often lighter and so your jump range can go up with upgrades as well
