Can'take really say for sure, but Ed Curtis from FTI recommended it when he designed my cam. it may not be needed for today's OEM roller cams, but most of them are not running the spring pressures and cam profiles that some of us are.

Currently, I use Mobil 1 High-Mileage 10w-30 synthetic oil and motorcraft FL-1A filter. My car had oil glaze build-up in the engine (no sludge though) from lots of short trips and usage of crappy standard jiffy-lube oil and no-name oil filter. 400 miles later, and the oil is already darkening. It's cleaning up the engine pretty good.
I'm currently using Rotella T6 in a jeep 4.0. Those have flat tappet cams, so it helps to have extra zinc. But, I've heard they reduced the zinc a bit in those oils also. I've looked up the Mobil 1 high mileage and it actually has a lot of zinc in it.
I use Brad Penn oil. Just remember that zinc is does not play well with catalytic converters.
Good read on how ZDDP (zinc dialkyldithiophosphate whichis in most oils that say they have zinc) affects converters here:

I literally tried to search MT catalytic converter for about 15 minutes and then realized I think you meant "My"....
I now know more about them than I ever wanted to.

Ftw, I have used synthetic oil and a motorcraft fla1 since I got my LX in 2007.
I buy what's on sale at Wally world, I've even used super tech a time or two.
I pass a smog inspection every year, and she has 316,000 miles and counting.
Im old school so 3,000 mile intervals is what works for me.
No oil leaks,thank God.
