Strange MPG...

Disco3's now got 6k miles on it, got used to a more or less contant 28mpg on runs and 24 round town, greenlaning would drop to 22 - ish but build back up on the run home.

So why is it now hovering around 20 Shocked yep, got a roofrack on but this is on the run home last night at 70-75 and round town this morning with no traffic queues. I reset the counter twice and it still settles around the 20 mark Evil or Very Mad has something broke?
Last long run with the rack on returned 26. something Confused

Where did you fill up last? was it cheapo fuel? perhaps a fuel station you dont normally use. I have found that lower grade fuel will effect the MPG.

Hey TFC, I had the same promble a couple of nights ago - saw 20 mpg - then it went horribly wrong from there - I woke up.

A V8 in TDV6 clothing... ya never know - I've heard stories on this site about miss badging and.. well, Laughing ?

Being serious for a min (yes, it IS possible), have you noticed any change in engine noise or performance - seems like too big a swing to be just an anomoly? On my old D2 (diesel) I had a restricted fuel line caused by dirty fuel contaminants (although the technician said cheap) and this surprisingly caused havoc with the MPG for a bit - cleared after they fiddled with some "actuator".
