I see, well if you're fuel hungry then go with expedition 2/5/21 and for sleep/afk go with 9/13/24. You will get loads of fuel this way and still get some buckets and the other resources as well.

Once you get more submarines you will be able to do some Orel cruising and that should alleviate your fuel problems. Also try to unlock the expeditions for world 5 if you can, as expedition 37,38, and 40 will provide you with a lot of resources as well.
