Does anyone really believe petrol like for like gives better MPG ever? It
may get close to diesel on the motorway, but loses out badly in town and
with short journeys.

So saying, both my cars are petrol and auto, and neither exhibits such a
wide gap between motorway and town - unless that shopping journey is very
short indeed. I won't use my car for a journey so short it doesn't heat up
to normal, as it is very bad for the engine.

Both cars are similar in that the town MPG is about half that of motorway
use (or slightly better). If 25% as you've said, I'd guess something is
amiss. Unless an ancient car on carbs with a poor auto choke. But I doubt
you'd get decent motorway MPG with that.
