Well, the ED30 can be very economical. I've managed to avarage 39mpg two tanks running using the 'fill to the brim' method.
BUT,...... I can't go on like this, as it's driving me MAD
It's unsafe to be driving for all out economy on our motorways. For 80% of motorway traffic 70mph is a mimimum speed, so trying to maintain 66mph (about 2500 rpm) calls for excellent anticipation and considertion for other road users - not to mention relatively slow progress. It's not something I enjoy and it's not a drving style I can adjust to. I realise some people find cruising at that kind of speed relaxing, but I feel much less in control and much more at the mercy of other road users.
I'm getting frustrated because if I drive the car how I want to (ie how it should be driven) every business trip is costing me money that I can't justify with the wife now not working for another year.
Luckily we managed to sell the wife's audi cab for a reasonable price, so we can get the Touran that we'll need, but the Ed30 will still definitely need to make way for something more economical at sensible motorway speeds of 80mph+ (diesel). Gutted that the car will definitely be going, but such is life ........maybe I'll find my way into a fast golf Tdi
