It really depends on your location. If you see low or subzero temps at night, (since winter is coming) then you need to get an oil for that, or if you experience high heat you need an oil with enough viscosity to withstand the temps.
My recommendation 10-30 10-40 or 20-50.

You know, that is what I thought when I changed the oil inmy '94 4.9. All ford trucks are 6 qts.
Dumped oil, changed filter added 6 qts. and I was way above full on the stick.
1k miles later changed oil agiain,( besy way to clean out an engine on a used buy, change it 4 times 1k interval), put 5 qts. in and I am only down one hash mark down the stick and way above the add.
Did they change specs or is my "stick" wrong?

I hate that stick! Mine reads a hair on the high side after a 6 quart change (w/ filter), but even in the owners manual (on my '95) it says 5 quart capacity, but there is a footnote and it says add 1 quart with filter change (theres your 6 quarts!) I know a couple people with the inline motor, and they all use 6 quarts...many miles and of course, no problems!

I'm pretty sure my '79 and '84 300s were 5 qts with filter change, but my '95 is 6 qts. It is usually ok for the oil to be a 1/4 inch above the full mark.

Thanks for the replies fella's. I think what I'll do is split the difference, since when I use 6 qts I'm 1 inch above the full line and add 1/2 qts (if needed) to bring it to 1/2 inch over the top of the full mark.
Appreciate the help.

Well, it's a lot worse to be overfull than under, under the pump will still pick up oil unless it's really low but over it'll get foamed up from the crank hitting it and the air in the foamy oil will make you lose oil pressure. Of course that's just really overfull...
