Nope, it was M1 0w40. Mobil 1 5w50 is factory fill in the Mercedes/McLaren SLR "Supercar."quote:

Interesting. Wonder why? I think M1 5w-50 was factory fill in the Aston Martin. Castrol is Mobil's #1 competitor.
I'm sure it's Formula R 0w40, which is fully synthetic.quote:

What sort of Castrol is factory-fill in the AM now? Is it dino or synthetic?

My guess would be because Castrol is a European Company while E-M is an American one.

Shell is the primary "first fill" lubricant supplier to DaimlerChrysler in Europe.quote:

I bet Ted would like Castrol's 0w40 though, since it's pretty similar to GC 0w30 in viscosity, it's only a slight bit more (12.9cst at 100c). So I don't think Castrol 0w40 would thin out all that much, since I don't think it contains very many polymers in it.quote:

Don't tell Tooslick that Castrol "R" 0w-40 is being supplied though. His panties lose their frills when 0w-40 oils are mentioned. According to him they are too sheer!
Ted - please just buy your non sheer knickers at Walmart and be happy!
It may not be right, but i've read that Ford actually only markets the motorcraft oil. They have a different supplier for factory fill.quote:

Funny, I figured that Ford Motor Company would be using MotorCraft oil to fill all factory vehicles.
You're talking about two different standards here. ACEA standards are A1, A3, etc. The API (American Petroleum Institute) is responsible for SJ, SL, SM, etc.quote:

Most Euro makers seem more concerned at minimising thickening than temporary thinning
as per the ACEA protocols.I thought there was all this talk of these modern SM oils were much better that the old oils, but if 5w30 still sheers then we should stick with 10w30.
With all this talk AGAIN of Sheer stability it seems to come down to the spec of the builder. If all engines were the same the 5/20 would be used across the board.
