I managed 40 mpg this morning which involved much restraint! And I wasn’t even stuck behind a dawdling OAP. Must be the high ambient temps making the engines run leaner than a Conservative council’s public expenditure budget.

I too have noticed a difference in average MPG between Winter and Summer.  And it seems to change like I've flicked a switch.  Makes me wonder if the ECU is programed to switch between maps on a pre-determined date?

My GTI managed 46mpg on a motorway run the other day.

I won't say that my previous GTD probably would have done 60mpg but  :whistle:

46 is pretty good I thought.

Definitely seeing better economy in the hot weather. I’m getting early 40s rather than late 30s on my morning commute

Its probably less optimal combustion and more to do with air density causing drag...

Air is 20% more dense at 0C than at 30C... thats a lot of drag.

In fact, that probably almost aligns with the difference in fuel economy...
