40mpg out of my saloon (heavy right foot and drive like stolen)
Aprox same mpg at 80mph on mway
I love it recently drove a brand new focus 1.6 eco titanium diesel on mway at 80 and best I got was 38mpg
Focus probs better round town but love my 20v, even managed near 40 mpg on a tank where just over half was towing a large folding caravan (so 3 people, baby, dog, luggage for all and a 750kg caravan) out dragged a top end disco pulling a caravan (his face was a picture) and still managed about 38mpg.
Totally love the 20v as it sounds and drives like a larger NA engine (low revving loads of torque). Even guy in garage at mot the other day came running round corner to have a look when mot tester revved it before emissions test as he couldn't believe it was a diesel and that's a mechanic who said he'd never heard a diesel like it and had to come and check as couldn't believe it was a diesel when he heard it.....
Anyway, if you get one hope you enjoy. Remember and floor it in 6th from 40ish to check for vibration in drive shafts... once you get it (unless receipt for change) I'd clean egr and hole in intake manifold and pop in altered gasket, clean MAP sensor and lastly I'd replace rubber tube on VGT solenoid with new cheap silicone as it will go. Last job has to be checking two intercooler hoses carefully, turbo to intercooler (bolt on gearbox for earth rubs) and one to intake has a habit of splitting where you can't see it... check for water pump change with cambelt as they have a habit of going and I'd say no more than 40k is safe.
