However, running 50-60% without a heated fuel system is a sure recipe for engine and fuel system destruction, landing you with a dead motor and a big bill, at which point the idea of savings from running cheap fuel starts to sound a little silly......

What exactly can happen? I am wondering if this led to my destroyed GP's and motor in my 84. I was running 100% biodiesel, already processed from a local biofuels company. I don't want to trash another motor if this was the reason. I am also running it in my wifes Jeep Liberty CRD (though not at 100% usually) and around 40% in my home furnace...
