Which Mobil 1 are you using? I know there are those who swear by regular ol' Mobil 1 5w30, but it's not high on my list of quality oils. We have two totally different cars, and while I don't buy into the some what unjust bias against ALL of Mobils products in some parts of the turbo-Subie community, I also don't find anything particular stellar about it, either.
I'm not worried about the mileage, but how the mileage has been accumulated. If your driving consisted of many longer weekend trips and fewer short-distance trips I'd be less concerned. As I mentioned in my previous post, the year+ interval wouldn't bother me one bit if you were only at 1,000 miles. With 5-6k, I'd say it's prudent to change the oil at the one year mark.
Were this my car, however, I'd send out a sample and find out for sure. You may find that the TBN indicates sufficient additive to carry you another 6 months or more, and that the oil properties haven't degraded much, either. If I weren't the type to bother with such things, a year would be my limit with that kind of mileage. It's much easier to remember than a mileage figure and doesn't cost much.

What oil? The oil chosen affects the OCI nearly as much as the type of driving, IMO. Except in the OP's case, time is all but irrelevant to me when it comes to choosing an OCI.

What oil and how many miles? 400 miles and two years isn't any big deal.
