As the temps have dropped over the last week or so have any of the members noticed a drop off in their fuel economy. I run a 2002 1.5dci extreme that usually averages 58-59 mpg on the trip. After filling up this week i reset the trip and now it reads 53-53.5 mpg.Do you think it could be winter diesel or something else.
Doesn't sound bad at all! You are running lights heater etc. That drop seems reasonable. What diesel make do you buy? I recommend BP or Shell as they have extra additives/cetane improvers and defintaley give more mpg. My 2.2 DT Grand espace averaged 41mpg on a run back and forth between Edinburgh and Manchester part day part night running on Shell.
