Why do you use 10w-30 when the manual states 5w-30 for all temps? Also, why do you change your filter so frequently?

I started with Mobile 1 5w-30 at about 3000 mi, with a Mobile 1 filter (it's expensive but it was on sale). I have about 7K on it now and will probably change it this week when the temps are back into the low 40's.
