The dashboard count for mpg has dropped from 52mpg-ish to 45mpg-ish. I fill up from the same garage (Morrisons) so not that. I have not checked against actual usage but will do so next fill up.
Ideas:
1. Weather? Don't think so myself but maybe?
2. Done 26,000 so maybe a software routing has decided to change it? 😅
3. Something needs servicing (but serviced August!).
Any help appreciated. Thanks.
