There are of course widely differing opinions on long term use of fossil vs
synthetic oil, but putting that aside, given that I plan to use synthetic
engine oil once the engine is broken in, what mileage/time is best to make
the transition. The car is a six month old Focus ZX4 ST with the 2.3 L
DOHC engine. I have only 3000 miles on it, but the first (6 month) service
is due next month. Is this mileage now sufficient for full break-in wear,
with fossil oil? I live in a mild area of coastal California, and the car
gets mixed use, mostly short-drive use.
Thanks.

You might double-check with your dealer, but if this was my car I'd have no
hesitation in putting syn into it on the next oil change.
