According to the Mobil 1 spec sheet:

0W20 is the grade of M1 that is recommended as equivalent to 5W20.

"Mobil 1 0W-20 is the ideal product for high revolution and output four and six cylinder cars where a 0W-20 or 5W-20 viscosity lubricant is recommended."
and
"Mobil 1 0W-20 is recommended for all types of modern vehicles, especially high-performance turbo-charged 4 and 6 cylinder gasoline..."
It does not mention 8 cylinders. Any thoughts?

My thoughts (and I could be wrong) is that if it's good enough for the small, high-revving engines, it ought to be good enough for the 4.6, especially if Ford has specified 5W20. I can't see any reason why it wouldn't be OK as long as it meets Fords specs.

That's what I'm looking into. I'll let everyone know what I find.
In my professional opinion I would say no matter how many cyliders. The oil either flows or it doesn't. one or ten. No difference just more oil capacity.
I found a site a few months ago that is doing some extended interval testing on synthetics.
It's very interesting.

We've covered this before, but DO NOT put in oil that is heavier than the recommended 5w20. There are reports of 2004 F-150 owners who have fried their 5.4L 3V, VVT mechanisms by putting in oil that is too heavy.
Use Motorcraft 5w20 syn blend, Motorcraft 5w20 full syn, or Mobil 1 0w20.

It's mobil1 hands down.
0W-20.
This oil is far superior to any mineral based oil.
It's hard to believe that the argument still lives.
The only other oil that is even close is AMSOIL (I hate to admit)
The synthetics have a much better detergent package, much better anti wear package, fine particle suspension for filtration, 0 viscosity breakdown between oil changes, better heat transfer, less common oil contaminants and on and on not to mention increased interval change time. I have been running Mobil1 for 20 years.
The extra cost by far pays for itself in performance and durability.
I have had several vehicles go 150k, 160k to 180k miles with little oil usage and 0 burning. Mobil1 in the long run is very friendly to the seals.
You will see no leaking like you will with a mineral base over time.
Dan, with all due respect. You can use factory oils is you please, but you will still get much much better performance with a synthetic. Mobil1 is fully API certified and exceeds ALL manufacturer specs, by far.
I am seeking some data from some Mobil engineers that I know on the comparisons of the 0W-20 and 5W-20 arguement. Mobil1's websit lists the 0W-20 as an alternative to the 5W-20. My 2 cents. I have used oil base stocks and synthetics over my entire career from hydraulics, transmission, compressor, gear, grease, etc. It's just one guys life experience. It's Mobil1 0W-20 for me.

I had several high mileage vehicle (700,000; 550,000, 210,000, several 150-200K range). My current main driver is 4 years old with only 172,000 and expect to keep it till at least 400,000. Every vehicle was weened of dino fluid withing the 1st 3,000 miles.
I'll change oil at 1,000 miles with motorcraft (free dealer oil change) and then at the 5, 000 mile mark. From them on it will be Mobil 1 5W-20 every 6-8,000 miles.
