I am new to this forum and new to my 2012 mazda 3 2.0 skyactiv. it will be due for its first oil change sooner than later as it has 3500 miles. or maybe not. i was wondering if a different grade than the indicated 0w 20 is ok. will a 'thicker' oil such as GC at 0w 30 be too much . i plan on getting a UOA on the FF . I have consumed about 1/3 of a qt so far , lots of short trips and stop and go. mpg is pretty subpar at 23 city and 29 mixed.
thanks
