I was told by the person i just purchased B100 from that it had a 45 degree gel temp. So are we forced to use less then B100 in the winter or can i do something to the car t continue using B100. I live in centeral VA so winters aren't too harsh, but diffenently below 45.
He also mention 17 degrees for the B20. So while up in NY working i've tried to guess arund B40, by cutting the B100 i brouhgt on th eroad with me with some regular deisel. BTW in Bufalo NY, last night i drove around for a half hour trying to find deisel, when i found it.........
$3.59 a gallon, WTF..i am glad as hell it isn't that expensive in VA. although it may be before long.

        A block heater will help get it started and warmed up, but it won't do anything for gelled fuel. You'll either need a fuel heater or run a mix of petro-diesel.

          perto - diesel ...what do you mean by this.
          i've read on other forums the anti gels don't work well. What fuel heater have people installed ?
          thanks. and yes i realized that the block heater was just to help get the engine started, not help with gelling of the biod.

            The problem isn't as much the block, though a heater will help, it is the fuel lines and filter can.

            I've run a mix of B100 in the Sierras, below 20's using Chevron anti-gel and injector cleaner without issue. You can run a mixture of biod and diesel during the winter as well.

                you know you can test the limits of the blend (of diesel and biodiesel and any additives) by cold-testing, right? put some in a jar, put a thermometer into it (check the supermarket if you don't have a thermometer handy) and record the temperature at which it starts to look cloudy. That's the lowest temp your fuel filter can pass that particular blend of near-freezing biodiesel without clogging . Then that's the blend you should use.

                Be aware that different biodiesel, made from different oils, will have different cold-weather behavior.

                  thanks
                  i also just had to replace the starter, that probably was part of the issue with not starting , but i will test the source of biod mix

                    Have you checked the glowplugs and glowplug controller?

                      you should also try having the glowplug holders scraped clean of carbon deposits, or do it yourself (kits available on ebay)... i had a mechanic do it, and car started starting up immediately, no more turning over on cold mornings!! it was that simple!!!! good luck! -f

                  It might also be worthwhile to mention that a lot of people run fuel-filters/water separators with a built-in fuel heater. Many vehicles already include this functionality. If your vehicle don't, you might check out what's available from Racor.
