Not exactly the model you're asking for, but my 528 Touring gets about 6.47 mi/ltr (24.5mpg) in mixed local and highway.
I just took a longer, mostly highway trip (1,300 km or about 800 miles round trip) and it got about 7.4 mi/ltr (28mpg) with an average speed of 125kph (78mph). Not bad for a car with 140,000 km (87,000 mi) on it.
that is awesome. I think my cars need to do much more as its a smaller engine than yours. One of the reasons i bought this car was that it would be efficient on gas
Any ideas how to get better mileage. One person told me to change the injectors. Its costs a good deal plus I am not sure if that's gonna help. Another one adviced me to change my air filter. Does that help.
