Here is a link from someone who posted their Blackstone oil results done on MC 5w-20 after 5800 miles. While its from a 4-banger engine I think it still gives some insight on how the oil performs.

Motorcraft oil is not a bad oil---------but a 4 cylinder Mazada is not a 10 ton MH either.

Are you all certain , a synthetic blend oil is truly synthetic? I understand that it is only a non-synthetic oil processed or refined to a higher degree than regular oil is why the cheaper price. Mobil 1 is not a true synthetic oil. A true synthetic should be used only with new engines and is a good detergent as well. Older engines using regular oil and then switching to a synthetic is not such a good idea. You will find he seals will begin to leak because of its high detergency factor. Redline Synthetic is a true synthetic lubricant. I use it in my Grand Marquis Mercury. A quality oil filter and a responsible oil change according to Mfg recommendation is all a slow RPM engine will ever need. WIX or KN oil filter are quality brands.

Whether it's a "true" synthetic or a highly refined dino oil, the differences in the end product are extremely small and not worth talking about. It's just an argument/selling point for the boutique oils.
It's also an old story that you can't change an old engine over to synthetic. That is left over from 40+ years ago when the first synthetics came out. Some of the very first synthetic oils had chemicals that shrunk some seals. The oils were quickly changed and it hasn't been an issue for 35+ years.
I've changed several old used cars that my sons had (1977 Scout, 1990 Ford PU, and a 1993 Thunderbird) to Mobil 1 without any issues.

I was told by my RV mechanic that a full syn would be fine to use if I want to. Considering that Motorcraft syn blend is recommended (and it's great price) I'll stick with it. I'm not all that happy that blends don't have set guidelines regarding their ratios. But I'm also not happy that the drain plug is right over the front axle.

FALSE! The V10 is not and has never been subject to any CAFE standards whatsoever! It has NEVER been used in anything other than HD trucks/vans/SUV's over 8600lbs GVWR!
Reality: oil is oil. Synthetics are better, but it just doesn't matter because regular oil is more than good enough. A V10 will wind up 300,000+ miles using whatever bulk 5W-20 or 5W-30 the company owning it can get the cheapest. I'd go with Wal-Mart's Super Tech 5W-20 conventional.

he V10 is part of the same family of "V" engines used in Ford's cars and trucks that are subject to CAFE. Sure would be funny (and hard to explain) for Ford to recommend 5w-30 or 5w-40 for the V10, but 5w-20 for any engine subject to CAFE.
Use what you want, believe what you want (you did read my link, didn't you). Doesn't make much difference, anyway, if you change often enough. And it makes no difference to me, what you use.
But there are reasons and a places for synthetics and the higher viscosities. A gas MH is one of them.

Ford does not recommend 5W20 in all its modular OHC engines. The 5.4 supercharged version used in the FordGT and GT500 use 5W-50 full synthetic.
Due to the timing chain tensioners being hydraulicly tensioned, I would suggest sticking with a 5Wxx whatever you decide to use.
Personally, our V10 in the motorhome uses Rotella T6 5W-40 which we also use in the gen sets, my diesel pickup and my wife's explorer and Harley. Only the Shelby gets special treatment.

That's quite interesting. That engine (although a very rare one) sees some pretty high bearing loads-----so a 5w-50 synthetic oil is called out. Guess such an oil wouldn't hurt a V10 in a MH either!!

Why would any manufacturer make an inferior oil?
