Diesel MPG drop?
I've noticed a slight drop in MPG lately, and on a forum I read so have
several others with diesel cars, as has my brother-in-law. Normally I'd expect slightly better summer MPG. Has anyone else noticed anything similar? Is there any connection with biodiesel in forecourt fuel? My usage patterns haven't changed.

I've only checked twice, but the mpg on my diesel Xantia seems to have dropped from a steady 44mpg to around 38. I'll check again when I fill up and let you know MIke P

I'm getting a noticable amount better than a couple of months back , though I am making a very conscious effort to drive more economically because of the huge rise in fuel cost -- Alex "I laugh in the face of danger , then I hide until it goes away"

Previously I've managed up to 55.

Normally I'd expect slightly better summer MPG. Has anyone else noticed anything similar? Yes, it's a bit strange I can hardly top 55mpg now, last summer I could hit 70, I was tinking it was just me having more fun and overtaking more. Is there any connection with biodiesel in forecourt fuel? My usage patterns haven't changed. I don't think there is much difference in the energy density of biodiesel, unlike bioethanol, and it's been in there for a good few years anyway.

I don't think there is much difference in the energy density of biodiesel, About 10%, apparently, although I didn't spot anything discussing the properties of a mixture.

Bio diesel only makes up a small percentage of what we get from the pumps so there will be less than 1% difference.

The brother-in-law reckons he's seen a difference between brands. I'll keep monitoring it.
