so if i get a oil change from dearler, i shouldn't drive up to 7k miles before another oil change??
because dealer uses cheap oil???

As stated above, if your driving conditions are "severe" then I would not reccommend waiting 7k but if conditions are "normal" then the book I have for a GLS V6 3.3 says every 7500k, which I intend to do and there is no requirement to use synthetic oil.
