Quote from "keep glow plugs on for longer" thread:
Well I for one have had issues with Biodiesel NOT talking about WVO. I maintain a fleet of equipment and trucks for a small government agency. I did not have any issues with the biodiesel "killing" the engines as it ran just perfect as diesel would. We ran B99 from two different suppliers. The last supplier is a large company that is well known in the Puget sound area. The problems we ran into where that it would gel at mild temps. The company told us that the b99 was safe down to 20 degrees before it would start to gel. We ran B99 through spring and summer but when fall came around and one morning when it was about 31 degrees outside or so every diesel truck and piece of equipment in the fleet would not run. I looked in the tank of one of the dump trucks and it looked like butter. And to make matters worse the B99 did not blend well with regular diesel. I would think that all the problems have been worked out with biodiesel now. This had happened in 2007, that was the last time we ran biodiesel.
V8volvo- You seem to be well informed on this biodiesel, so at what point does the B99 gel at? Was that bad chemistry for the B99 we had or was the guy that told us that it was safe to 20 degrees full of it?
