When did you last service it. Strictly no more than 5k ago if you want economy.
My 405 has done 900 miles to 80 litres, rounded down that's 51mpg. It's got a hdi box and serviced religiously, I also pay particular attention to other aspects of the car that affect MPG's, such as tyre Quality and brand, pressure depending on what driving I'm doing, correct + clean gear oil, engine oil, filters, no boost leaks, I have tracking done every few months or if it starts pulling, I clear my car out but still have toolkit in a bag and a spare wheel. Suspension is best shape ever
Oh, and you could probably up my mpg if my speedo wasn't about 10% under.
