Loc: Sweden / Stockholm Since i have a S60 2,5T 2005 i can post something about my service history...The first 3 services is done with approximately 18000 miles intervalsand now i drive much less per year so its enough to change the oil once per year.I know that in the U.S its considered insane to run 18000 miles between oil changes but i guess that my car is an example that its possible to do it
