Hey...so I am doing my first oil change and I obviously can't find any aftermarket oil filters (e.g. K&N). I know they have one for the 3L mazda6. Anyway...what oil filter should i get, oem or some other brand if they have one, and then what oil is recommended? I read a couple posts about oil, but i was wondering if somebody had a better idea as to what oil was best. thanx
