If or when you decide to go to bio-diesel do you need to increase the change out time on your fuel filter. I know at first when you switch over to bio theres a possibly of changing out the filter 2 or 3 three times due to the cleaning affect of bio. I've never tried bio-diesel and have always changed my fuel filter at 10K intervals since truck was new with no problems at all between intervals with regular #2 diesel, now here recently B20 bio-diesel has become available very close to me and I'm debating on trying it out. What about alternating fill-ups say you run bio 3 or 4 tanks and go to regular #2 diesel a couple tanks then back to bio. Just some questions I'm pondering over.
Also the mileage is it the same, better, or worse using the bio-diesel. Some of the testimonials I read on the Bio-Willie site are claiming 2 miles to the gallon gain. Some people I've talked to say bio-diesel reduces your mileage. What's the scoop from the one's that use bio on this site.
