Propel HPR Alt diesel in California

I am new to the forum. Have you already discussed the merits/challenges of Propel's HPR alternative diesel fuel in the Bay Area of California? I have been using it almost exclusively for a year in my 3013 Jetta Sportwagen and getting excellent results. BTW, it is $.15-.50 cheaper than the petro diesels in my area and $1.00 cheaper than any of the gasolines.
Look up www.dieselhpr.com and please comment.

Several large threads already on this. Don't know how you missed them.
