Hi, The MFD on my new to me Caravelle suggested oil service last week (due in 1500 miles came up on screen). I booked it in for a service as I have All in plan and it's off to dealers Thursday by which time it'll be down to near enough 0 miles. I checked service history and it seems it had oil/filter in January just 10k miles ago. This doesn't seem to follow, fixed or flexible schedule. Any ideas? Perhaps not reset after last service?
