Octavia VRS diesel MPG

Hello,

Strongly considering a diesel VRS to replace my Seat Arona.

I do 1200 miles a month commuting and have additional on top for other journeys here and there.

I struggle really to get better than 40mpg in the little 1L petrol I have at the moment and generally cruise to work on dual carriageways at around 65mph. I can take either a 38 or 56 mile round trip.

Anyone got the same car or similar (GTD / A3) that may shed some light on the MPG I could be getting?

I'll be doing all servicing short of belts myself to keep costs down.

I'll also have my bikes on the roof from time to time and tow a caravan in the future too.

Cheers.
