Used them once, no issues but decreased economy is entirley expected, due to many things. Engine timing, fuel calorific differences for starters.

Umm, that's like 8% (if my calculations are correct), seems a little high for B20? I'd expect about 5% on B100, give or take a few %. Am I missing something here?

I guess driving conditions, vehicle and all sort of factors play a part here, so we could allow for some of this. How accurate are your measurements?

When you say an "increase in fuel economy", I'd guess you mean a decrease, or an "increase in fuel consumption.

I am sure many issues come into play here but I have a landcruiser it got 93Kw on mineral and 88kw (at the wheels) on B100 with a stock standard timing regime. No allowance has been made for biodiesel and who knows aht the injection pump is really doing.

The Peugoet on the other hand is computer controlled, its quite predictable. I have one friend with one of these (2006 model) and he had it in for some work and they ran an upgrade to the ECU, he know states its runs better on biodiesel than on mineral and the mechanic stated he did not knowof another 307 with the same go from start. From this I think that he has the timing adjusted for biodiesel and its low end torque delivery is due to the nature of B100. So there are many things in it, I just wish I could get my 307 tuned like this!
