My wife has a multijet sporting and on dual carriageway we have to drive at 60mph to get close to 48mpg.
Surely this isnt right?
Car was serviced back in June with new diesel filter cambelt etc.
Is there anything else like a dodgy maf sensor that might affect the mpg or is this usual for a diesel sporting?
Cheers,
Marc
A dodgy maf would cause poor fuel consumption but I wouldn't class 48mpg as poor. The multijet isnt the best diesel engine out there really for real fuel economy.
Mine averages around 43 on very short runs and on a good distance run such as 50 miles it will average 50mpg. Mine has been remapped though so before the map it wasn't as good on fuel either. On a long motorway cruise I can see it average high 50's but that's trying hard The trip computer average will say around 63ish but when you work it out its never actually that. I usually get bored and my heavy foot ends up taking over so my usual average overall is between 43 and 45mpg.
