I'm getting ready to change my oil in my 1985 Ford F-150.
The engine is a 300 Straight Six, 230,000 miles.
What would be the best oil to get?
What brand? What weight?

I personally like using 10w-40 on older such as what you have and any brand that uses dino oil, (valvoline, castrol, penzoil, quaker state, sinclair, amsoil) and a little blue bottle of STP oil treatment as it's very high in zinc and that's good for the engine. For oil filters I use Wix

I've ran Shell Rotella T 15w40 for a couple years with absolutely no problems. If it's good enough for dirty, sooty diesel engines in semis, it's good enough for a much cleaner gas engine.
For filters, I've had good experience with Motorcraft and Wix.
i agree with the 10-w40. as for brands i'd go with fepowerguy said. pretty much all of them out there except for noname in-store brands like a proline, coastal, autozone (if they even make it). i guess a decent rule of thumb would be if you see the oil company advertise on nascar it's a safe enough brand to use (haha).
i usually watch the circulars and pickup whatevers on sale at the parts store. i think advance is running a special now with castrol oil and a puralator filter. i picked u some of those.
also, i've used fram, motorcraft, puralator filters and never had a problem. you'll see a lot of people swear off fram but i've had good experiences. i think as long as you're changing your oil every 3K it doesn't make much of a difference if any.

I totally agree. I use 15W-40 diesel oil and wix or motorcraft filters. Rotella is usually the easiest find, as nearly everyone carries it.
I'm one that will not touch a fram oil filter. I've had people try to tell me they are fine, but I've seen one that ruined an engine. I believe in the adage of "screw me once, shame on you, screw me twice, shame on me".

Currently I'm running a Napa brand filter (it was free) for a 460 on my 300. It screws right on, and is almost twice as long as the standard filter... more capacity and filtration can't hurt, right?
I don't know for sure about the standard NAPA filter, but the NAPA gold is made by wix.
