well ford has the complimentary service at 3,000 but they wont change any oils. they will just give everything a check over. check oil levels. all fluids etc..
I suggest servicing between 1,500 and 3,000. then i believe first oil service is at 10,000 then at 15,000 i believe. (dont quote me on that)
but yeah with normal driving, very low reving etc u should be okay servicing at ford recomended intervals.
but because we are young... and we like to fang our cars a lil u should really service at least once between ford services.. BUT BUT BUT use genuine ford filters otherwise you might have your warranty voided if they find a filter that aint ford (it would tell em that sumone else has been servicing car, which they dont like)
personaly im going to service my car with fully synthetic oils every 3-4 thousand K's. i dont drive my car much so it takes me a long time to rack up K's
