I just did the 6 month oil change on my '98 F150 w/4.6L. I thought I had the WM 5 qt jug + 1 qt of Havoline 5W30. When I looked in the cabinet in the garage, no single quart. I did have a quart of Castrol GTX 5W30 so I used that rather than drive to the parts store for Havoline. Will this make any difference?
I should add that I only drive it about 2500 mi every 6 mo. I try to do the changes at season changes, which aren't drastic here in Tennessee.
