For a suggestion to your problems, make your own bio-diesel. If you have a diesel vehicle, then you can make your own Bio-Diesel (check if you need a permit in your area). It burns cleaner than regular white Diesel, and it costs like $50 to make for 100 gallons. The only setback.... it makes your vehicle smell like fast food fries. Yeah, the main ingredient is the vegetable oil that fast food restaraunts use to fry food. Google home-made diesel and see if you can find a guide. I know they are everywhere.
