Ok my 08 F150 5.4 4x4 does not get driven much at all since I commute in my civic about 90 miles a day. So today it hit exactly a year on its current fill which is PU 5w30 and a Motorcraft filter but the fill in it is at 91,530 and it now has 95, 200 so 3,670 miles in a year. That's kind of funny. So my concern is should I change the oil because of age or keep the fill till I hit some more miles? As always thanks for the help.
