Which would make sense, because engines consume fuel (duh), and if you run out, you lose power and your ship becomes slower and slower over like 10 seconds until it comes to a stop, then the engine dies.
this would help stop kiting, and encourages drifting, which wouldn't consume as much fuel, since the engine is idle. = more skill involved + more realistic.
This would also give tankers a useful role, refill fuel to ships around them as a ship system, because right now, tankers are pointless unless you want to sit in hyperspace for 30 years.

id imagine this would only need an extra tab in the CSV as well such as fuel consumed per 1000SU or something
whole idea started because I feel I don't have enough to think about in battles, and generally because i want some kind of realism in battles other than blowing stuff up, and because i feel fuel is completely useless right now and only serves as extra money until you have to travel somewhere which barely consumes anything to begin with, i figured it should be given the same kind of importance supplies have.
Thoughts?
