The good news is that VW will begin selling diesel Jettas and Rabbits (or Golfs) in the US soon. So, find yourself a diesel car, and check out these fantastic how-to’s.
Convert your car to biodiesel. Yes, a small conversion is necessary. Vegetable oil will harden in the cold, so you can add elements to run the car on diesel until it warms up and then switch to the vegetable oil, or warm the veggie oil tank so it stays in liquid form.
Make your own biodiesel processor. A small amount of processing is necessary – simply to remove food particles from the used vegetable oil. For the time and energy used, it’s well worth it.
Finally, how to make your own biodiesel. Easy as pie. No more gas!!
If you do any of these things, please keep us posted. It just makes so much sense to reuse vegetable oil and run your car with it. Diesel engines were invented to run on vegetable oil.
