Does anyone use it?  Anyone who does, have you had any problems? 

Here in Europe there is all ready biodiesel being used as a percentage of offroad and road going diesel. There are problems with bacteria growth in filters and seal breakbown in sight gauges .Any machines that are parked , particularly farm machines that are used seasonaly , are at risk from fuel that is growing a bacterial bloom in the fuel lines and pumps. House keeping is vital to keep right and fuel needs to be kept on a tight turnaround.

Have a friend in Witchata,Ks that runs about 8 states with his lowboy,loves it,and the savings too!!!

I have used it in a few of my personal vehicles with some good and bad results.  I think I got the bad results from buying bad bio.  I might have to look up the uses of Bio in europe.
