Before doing that you just put any fuel in the first slot and type "refuel". Maybe there's a more complicated way of doing it, but I don't see the point.

You may be better off with a quarry. You actually can do a lot more than just excavate, look up tutorials on youtube, turtles are great after you learn Lua
