Hello,
My usually reliable biodiesel co-op sold me about 15 gallons of fuel tainted with sludge. I'm getting some serious debris in my 1985 300DT's prefilter. (Likely not all 15 gallons are bad; just some of it.)

Ideally, I should probably just drain the tank, but I have 20 gallons of fuel in the tank and no place to put it. Think I can just run the car and keep changing the filters as they clog?

Thanks for any advice.

Joe
