QUESTION Efficiency drop after 2.5 update

[MRU]

@MRU @chips @Samo23 Several of you noted drop in efficiency after an update. Have any of you contacted SC for a reason why? I noticed ours dropped after the 2.7 update.

It’s summer now and I’m still getting sub 2.5 numbers. Lifetime is 3.30 now and slowly creeping downward. I’m kind of resigned to it by now, just enjoying driving every time I take it out. I do have a service appt next week and will ask if they have an explanation.
