I finally got around to taking my E90 out for a decent drive - four up we left Durbanville mid morning and drove out to Montagu. Filled up just before we left and overall consumption is shown as 8.7 ltr/100 km - iirc average speed was around 87 km/h. I "mostly" stuck to the speed limit (plus a few short of 10 kays over) but let's be honest, there were a few good opportunities for some liberal use of the right foot, and performance and fuel usage put a smile on my face! 
Also made good use of the cruise control which is also a pleasure to have on those long straight bits. The Conti run-flats are a pain though - the front set are noisy and while the handling is good the tyres do tend to make the car a directionally unstable on varying surfaces. Mostly at low speeds but even on the open road the car tends to want to go where the tyres take it - means lots of correcting and inevitably some lateral motion which isn't pleasant. I have heard lots of complaints regarding run-flats in general and for that matter the Conti run-flats as well - also that this directional behaviour as being a characteristic of the run-flats with their harder side walls. Anyway, will have to investigate my options - am going to be getting the space-saver and ultimately ditch the run-flats.
So 8.7 ltr/100 km and the trip was roughly 352 km - fuel gauge is now just slightly over half remaining! When we arrived in Montagu the fuel consumption was on 8.4 ltr/100 km but we did buy a few boxes of wine and I was sticking to a higher average speed.
All in all, a great day out!
