I am also a bit unsure of how to go about making this conversion. Can I run both Diesel #2 and biofuel? Do I need to "prep" this biofuel? Can anyone please help me with this?



Yes you can run either in your car with no alterations. That said, there are a couple of things to watch for though. If running a high percentage of bio, your fuel filters will probably clog after the first tank or two. Bio cleans out the petroleum buildup that has been accumulating over the years. After one or two filter changes you are home free. Also your engine will run quieter on bio. Thirdly, bio will slowly deteriorate old fuel lines. It took 45,000 miles of 100% bio before mine leaked, but they should have been replaced prior to that. Total cost of bio resistant fuel lines (except the one leaving the tank - haven't changed that one yet) was under $40. Not bad for 50,000 miles at less than $1 / gal.
