Consumption 2.5 DTI?

Hello guys, I have to decide between the Volvo S60 D5 and the Omi 2.5 DTI. Can anyone tell me quickly what the 2.5 DTI really uses? I know this is indicated with 8.6 l, but does that correspond to reality? Or does the Omi consume more or possibly even less? I drive about 60% highway, 30% city, 10% country road. Thanks already.
