I'd actually like to see a poll done for this question, just to see the margin of synthetic users and how long they go w/o changing the oil. Personally, I got 5k miles w/ Mobil 1 5w-30 w/ motorcraft oil filter.
Did these all the time when i worked at Valvoline Instant Oil Change.....basically its a product you add to your oil (b4 draining it) run your engine w/ it in there for about 5-10 mins, drain it, pour fresh oil in untill the oil coming out is no longer black and it is actually very close to the color of the fresh oil your putting in (translucent), put in plug, fill up w/ oil, the end.
W/ a good syn, if you have ALWYAS used it for the life of the car then you really shouldn;t need to do it very often at all...maybe once every 5 oil changes if you want to be very critical about it.
