Best oil for 4.2L?
Ok, I'm hearing a bunch of guys giving kudos to Motorcraft 5W-20, but since like ever I've been using 5W-30 per the owner manual? My (new) engine has 26K miles on it, so still in the break-in period but what do you guys recommend for my next oil change? BTW, I use Motorcraft oil filters, but I'm thinking on trying one of those new K&N Gold oil filters next time and see how it does.

I have used Mobil 1 fully synthetic oil in all my vehicles. I used to use Fram oil filters for years but have learned (on this site) that they are not the best to use due to not having an "drain back valve" or something like that. So, I have started using the motorcraft filters on my truck but I stick with the Mobil1. 102K on my 4.2 with no issues. 126K on my 97 4.2 when I traded it in.

For a solid baseline, on Jan 01, 2008, I began tracking my mileage on www.fueleconomy.gov
Here is what I see so far:

If we all used it, then it would give an interesting comparison of driving habits, fuel type, different fuel mixes by State, and mods.

Wally World is as good as any as long as they have what you want.
I get my oil changed at a local Mobil 1 Express Lube. He doesn't normally stock 5W20 EP. I call him a week or so before I come out and he goes over to Wally World and picks up 6 quarts. He says it's cheaper there than from his distributor. 52 bucks for oil, filter,and lube, including tax - and he uses Mobil 1 filters.

An online store for Ford Mustang parts, http://www.americanmuscle.com, sells Royal Purple @ $6.49 per quart with free shipping.
http://www.amazon.com has a pretty good price for K&N Filter.
My local corner gas station mechanic does oil changes for $15 for labor if I bring my own oil & filter.
The Livermore Ford Dealership offers a $5 oil change.

lol all this about brand name filters. Honestly dont think it makes a difference. If you change your oil regularly in the first place... no filter will have any problems working right. I doubt a wix will work better than a k and n, and a k and n better than what the gas station will put in.
Stick to putting money into good plugs, wires etc, instead of stuff you just really wont see a difference with.
Ps synthetic oils do help and do last a tad longer... but just to stay on the good side of your truck clean it every 3 at most just to keep it running consistantly.
Autozone is fine. So is wallmart. Idk why a shop would make any difference besides price. Id rather pay a buck more per quart and go to allparts than take the trip and waste time in walmart. (5 or 6 bucks really dosent compensate me to stand in line nor walk alll the way across a huge store.)
