5w30 flows better cold, and with overhead cams, it needs to get oil up there quickly. I usually run 5w20 year around, I have started going to 5w30 in my 300,000 mile Grand Marquis, and probably will next summer in my Mark VIII. With as noisy as my cars are with the Fram orange can of death, no way I don't spend that extra 1 dollar and get Motorcraft FL-820S with the much better end cap and ADBV. I used the run 5w20 Motorcraft synthetic blend, but generally use Mobil1 full synthetic. Lots of 4.6 owners swear by Pennzoil Platinum, but I had a very high consumption rate with it.

I found the Motorcraft FL-820 filters cost less than most filters. Got 3 on Amazon $3 and change, and found some at WM around the same price. Regular drivers get changed 3-4K miles. Just did my CE, 949 miles, but over a year old. A couple of times my 95 got changed at 1K, I forgot to reset the oil change feature. OIL= life blood of the engine, change it often
Amazon has pennzoil ultra platinum 5w-20 for pretty cheap plus you can use the subscription feature for a little more savings. I've been using that with the wix XP filter and my oil stays noticeabley cleaner longer than with the mobil 1 filter i used before. I think with the subscription it was around $5 per quart and $7 for the filter? I bought a boatload of oil and filters when I drove 2000 miles a month now I drive maybe 500 miles a month and have oil and filter stockpile for years.
