Cool , and ya bought it last Saturday it had 12 miles on it. Thanks for all the replies .. looks like I will just hold off.
In that case, I'm almost certain it has the Motorcraft Synblend. I'd hold off till that 3k mark. Then go full synthetic. I use Mobil 1.
i waited till i hit 500 (comes sooner than you think) and then i put fully synthetic in it and thats all ive had since. works for me
