Mobil 1 vs Castrol Edge (8 x better)?

What evidence do you have that Mobil pays GM to use their oil?
The fact of the matter is the consumer does not have enough data to make an intelligent decision about what oil to use. The oil spec that a car manufacturer suggests meets the requirement for the needs of that engine. Things like gasket material, aluminum or alloys vs. steel engine components, RPM range, bearing clearances and size, tolerances between parts, operating temps, thermal expansion of engine components, etc. Just because an oil manufacturer says it is 8X better in one catagory that doesn't mean it is a better oil for your application. Use any oil that meets the spec suggested by the manufacturer and you will be fine. The guys with the lab coats have all of the data, you don't.

Truth of the matter is, as soon as Wal-mart's super cheap Super Tech synthetic shows up on the shelves being 4718M certified, it's just as good as M1 or Castrol or Amsoil. And it meets the powertrain and emissions warranties.

I have 500,000+ miles in Corvettes using Mobil 1. Two of my former four Corvettes (C4s), each with nearly 200,000 miles on them when I sold them, now have in excess of 300,000 miles each. One is living happily in Austin, Texas, the other in Paris, Texas.
Can you imagine? Had I used Castrol those same Vettes would last about 1.6 million miles. Why oh why didn't I use Castrol?

I have always used Mobil 1 5W-30 as recommended by the manufacturer. However the 5 qt Mobil 1 at $22.00 in Walmart always seems to be out of stock so I am about to try the new Mobil 1 AFE (Advanced Fuel Economy), that comes in 0W-30 viscosity. The Mobil 1 website and the bottle both say that it is 4718M certified and meets or exceeds that standard. The $10 coupon for Mobil 1 is no longer available but there is a $10 rebate on the www.mobiloil.com website available after you take the quiz to see how much they say that you will save per year by switching to the new AFE oil.

Damn, I hate it when that happens !!!!!! 
I watched the video that was an ad banner here on the forum website. 8X better is what I would say a big improvement. What do you guys think? 
I watched it with an open mind and they did a good job beating down Mobil 1.

0w-30 is the way to go. Same high temp protection as 5w-30 but faster start up lubrication where most wear takes place. Even in say, Miami Beach.
I'll go out on a limb and say before too long 0w-30 will be the factory fill and recommended oil in Vettes.

If you're not under warranty, 'nuther story.

You can use it from day one, and GM tends to agree since that's been the factory fill in all Vettes since 1992. Rings will still seat perfectly fine even if synthetic oil is used for the initial fill.

The Mobil 1 bottles I have read recently do not say they meet the GM 4718M spec, while Castol EDGE, Valvoline Synpower, and Quaker State synthetic do list the spec.
Castrol and Valvoline both claim they provide better wear protection than Mobil 1, and technically Mobil 1 does not even pass the wear test.

Nothing wrong with Mobil 1 but I would never base a decision on what a race team with a relatively unlimited racing budget (compared to a weekend racer) advertises and/or puts in their race cars.

I run Mobil 1 in my vette. I ran Castrol in my track car. I've had no issues with either. In the end, my personal opinion is that in either case we are all gonna be just fine.
