Civilian vehicle gasoline does not change. If you bought a vehicle before this bug, it stays at the same gas level despite if you refilled it and immediately respawned it. If you bought a vehicle after the bug, it will stay on 20/20 and drain when you use it, but like a department vehicles, will be full upon respawn.
