Hi all. I need to schedule service for my 2007 QP and the dealer mentioned I need to get 31K service done with spark plug changes, etc. The thing is that my owners manual does not show that service. I think Maserati changed the service intervals starting 2007. Mine only shows 12.5K, 25K, 37.5K mile service and spark plug replacement at 75K miles. I always get oil change once a year around 7K mile intervals. Is anyone else with 2007 and later QP's getting the bigger 31K service or just following the manual?
