Something is not ok with your acceleration from 0-100km / h, it should be 8.4sI'm having 10lt/100 km (28mpg) and 0-100 11sn. Something wrong I guess. any opinion and what is your numbers?
On my XC60 D5 average fuel consumption for mainly city driving is around 9-10l, open road it’s below 8l. On my other Volvo, XC40 D4 I see almost identical numbers.Today mine also decreased to the average of 8lt/100km-35mpg with new fuel. Because of it waited for one month with the same fuel that happened I guess. For performance I'll check what happens, maybe it will also improve.
