The reason I ask is because I did a lot of driving north to the cabin last year and we have a Murphy station outside a Walmart that had the lowest price so I filled up there on a pretty regular basis. In looking at their pumps, I saw they had a sticker that said their diesel could contain "up to 20% biodiesel". Now, in Minnesota we have a mandated 2% biodiesel requirement for all diesel fuel, and to my knowledge I've never used anything higher than 2% biodiesel before.. I didn't think to much of it until I changed my fuel filter at the end of the summer. I was shocked to see that it looked like no fuel filter in my truck that I've changed before, and I've changed a couple dozen since I got it. The best way to describe it is that the filter looked somewhat melted. It was all still there, but something had really been working on it. Now I'm wondering what other components might have been affected. Since biodiesel is a solvent, that would also explain why your tank was so clean? Just something I thought I'd pass along.

I ran a tank of bio about threee years ago,there is also a station locally that has pump bio at 5 to 20 percent,but I've only topped off with it a couple times,and that has been a couple years ago.I knew bio was a solvent too,but in changing my filters there has never been any that looked odd,as a matter of fact,when I first noticed my power issue,I knew my fuel filter hadn't been on long,but I took it out to look at it anyway and it looked good,very clean.
