Few days ago I picked up a 5 qt jug of 10w-30 for mine. I change my oil every two years.
Now before you say why so long consider the mileage I've put in.
Bought car in 2008 with 83126 miles on the clock.
First oil change (with filter):
09-05-2009 with 85160 (2034 miles)
Second oil change:
04-08-2011 with 87351 (2191 miles)
Third oil change (with filter):
08-19-2013 with 91239 (3888 miles)
Now I'm at 94318 (3079 miles). Yep, time to change the oil.
