Rust Vehicle Fuel Per Minute
A minicopter burns 30 low grade a minute whenever its engine runs, hovering or flying, so 100 lasts about 3m 20s. Boats burn their full rate only while you hold the throttle: 6/min for a rowboat and 15/min for a RHIB.
Methodology
Tested in game on our own server. We filled the fuel slot of each vehicle with a tank size shown, and ran the minicopter, scrap transport helicopter and attack helicopter for a timed minute to count the fuel they burned. Tested on the current version of Rust.
