someone (OAC_sparky?) posted in another thread that ford is able to extend the oil change interval that long because the factory fill oil is semi synthetic (the key advantage of synthetic is extended oil change interval)
IMHO follow the severe service oil change interval
if the 'severe service' maintenance schedule says 12k kms between oil changes i think you are fine with that interval. if you are worried change it at 5k kms and get a used oil analysis done to measure the amount of additives and wear metals. if there is a lot of additive left and the wear metals are within normal range then go ahead and stick with the longer interval.. oil analysis a great way to bring tech to this decision
EDIT: as for the extended warranty, it is good for peace of mind, or if your car has had a long history of needing repairs, or if you really drive the crap out of it regularly. if its a normal daily driver that has had routine maintenance and inspection, you might be better off not getting the warranty. (they price those things so that they make a profit on average... or else they go out of business!!)
and read the fine print to see what is included, where you can get repairs done and what the claims process is. and get a competitive quote from another vendor
