Another Bio question

I've been running B20 a lot for the last few months with no problems yet, not even any fuel filter troubles as I was warned I'd probably see. In my neck of the woods it's cheaper than regular diesel, and good lube too. I don't use any 2 stroke oil with it. I have had one minor fuel leak that comes and goes that I still havent' tracked down, maybe from the B20, but probably just reality with a 12 year old rig with 225K on it. No idea on gelling.

Fuel leaks are kind of a urban legend in my mind for newer than early 90's trucks. Natural/butyl rubber won't stand up to BD but our trucks use viton seals and what not which will hold up to the BD. Most don't experience leaks after using BD. Gelling is a problem depending on temps but I don't know what temp B20 will gell at. Your best bet would be to get a mason jar of B20 and stick it in the frig. if its doesn't gel then put it in the freezer. Check it every now and then and measure the temp of the B20. Once it starts to have particles drop out that is the where you are safe to run it. Some anti-gell additives will help.

Ditto on what TJ said. Even b100 shouldnt hurt our trucks any. the reason for this was in 1993 a law set in that enviro freaks wanted to mandate that everything be prepped for the upcoming fuel changeover. Still waiting to see that change, but atleast our trucks were built for it. If you have a 1993 or pre 93 truck, you have to switch out ALL rubber lines for fuel system. Fortunately for you, you waited and bought a truck that was bio compliant. Thats right. I really know some stuff.... WOOT WOOT.....LOL

When biodiesel and diesel are blended, the cloud point and thus the gel temperature, changes for the fuel, based on its composition. The following table captures these changes:
Biodiesel Concentration (vol. %) with #2 Diesel.............. Cloud Point (F)
............Regular Diesel............................................ ..........3
............B10................................... ................................5
............B20................................... ................................7
............B30................................... ...............................14
............B50................................... ...............................18
............Pure Biodiesel......................................... ............32
At biodiesel percentages of 20% or less, the likelihood of gelling is indistinguishable from regular diesel. This property allows biodiesel blends of B20 to be used without changing the fuels normal winter blend of #1 and #2.
