I don't remember if it exists in stock, but check under the navigation section of the command bar to see if there's a "Maximum Range" option. I know it exists in mods, and I have a hazy memory of it existing at least in the commands file, but not with a key assignment.

If it does exist, use it at various speed settings to get an idea of the most efficient speed. You'll find that running at high speeds will severely reduce your distance to fuel ratio. Running across the Pacific at lower speeds is not as exciting, but for most of the way, you can use rather high time compression. Just remember to lower it when you get closer to Imperial waters, or you'll be sunk by a plane you never even get a chance to notice.
