Is There A Way To See If A Move Requires Fuel

im wondering if there is a way to detect if a move requires fuel without actually trying it, or will I have to put all moves that do in a table?

If fuel is disabled then turtle.getFuelLevel will return "unlimited", if the function doesn't exist then the version of CC doesn't have the fuel requirement, other than that, any time a Turtle moves from one block to another it requires fuel. Nothing like turning the Turtle does.

So a good fuel checking function would be

local function enoughFuel( required )
  --# if the function doesn't exist exit the function
  if not turtle.getFuelLevel then
    return true
  end
  --# get the fuel level
  local fuel = turtle.getFuelLevel()
  --# return whether the fuel is unlimited or there is fuel to move
  return fuel == "unlimited" or fuel >= required
end
