Bio-diesel / Is it a good or bad thing for the engine ?

I went to fill with diesel at my favorite Chevron station, and I noticed the diesel pump said something like S15. I had no choice at the time, so I only put in 10 gallons, cause I knew I could get better stuff later. A guy at the station remarked that it was ****, and bad for the engine and injectors. I get the environmental part, anybody know the facts about it's effects on the engine?

    Bio D can and does retain water. It is hydroscopic. It will hide in the fuel itself.

    Todays new fuel systems do not put up with ANY water. The pressures they run now days will kill the pump or injectors in a heart beat.

    I do not like the stuff nor do I use it when there is straight #2 for sale.

    Todays modern fuel systems cost 15 grand+ to replace. "Do you feel lucky? Well do ya?"
