Interesting coincidence. I've been up in the Bay Area for the last few weeks and found the "Propel Fuels" vendors offering B-20, so I've been running my '98 on it for the first time ever. (I was hoping for a quick cure for the one-cylinder nailing at idle & cold start miss issue, but alas no miracle occurred.)
Before heading down to So-Cal today, I went to fill up at a different Propel vendor (in Oakland on Grand Ave.) and found this HPR stuff instead of the B-20. I filled up with it (half a tank) so I effectively had a 40/50/10 mix of D2, HPR, & Biodiesel. Ran the car HARD, and I mean REALLY FLIPPING HARD on the I-5 Autobahn to hopefully blow out as much carbon as possible prior to attempting glow plug replacement in the next week or two.

If this stuff truly has an astronomical cetane rating, it will be interesting to see how it starts in the AM tomorrow. If it helped smooth out tjts1's cold start, I wonder if it will decrease my cold start single cylinder miss & nailing. I'll revisit this thread and keep you updated.
