I think 3 months is far too excessive, I have changed mine about every a couple of times since the beginning of last march, but that was out of necessity as I had a dpf issue only a couple of months after having a oil service and just thought it prudent to change it again as a matter of caution at quite a bit of diesel was injected into the sump due to numerous failed regens.
I have not done a oil and filter change for around 6 months and will be doing one shortly but that is down to the fact that our car rarely does any motorway mileage or speeds above 40mph which effects the dpf regen. This is purely a personal point though, my oil life sits at around 50% and I visually check it with the dipstick at least once a month to check levels aren't increasing. I could leave it for a lot longer but I like to tinker by nature, so I have 5 litres of Shell Helix ECT C3 and oil filter sat in our boot as I type.
Oil life will be a calculation purely based on mileage and dpf regens since last service, but in reality there is probably a lot more life in the oil than the computer stipulates, they just air on the conservative side. If you want to do oil services every 3 month or 6 months it is a personal thing based on your preferences and the type of journeys you take, but generally speaking, every 12 months is perfectly fine for the majority of drivers.
I am more inclined to stick a good diesel engine treatment and dpf cleaner in the tank 2 or 3 times a year just to help keep things nice and clean.
