V12V - which oil and viscosity?

[Mako V12V]

I'm toying with the idea of supplying my own oil (subject to AM MD approval) for the car's second service.

Looking at the first year service invoice it just says:-

Part number MSLX

Castrol fully syn oil - 12L


Specifically, can anyone help on the exact Castrol oil and its viscosity?

Thanks

It's in your owner's manual

I'm going to guess here Mako but it should be 0/40 fully syn either Castrol or Mobil 1.

That's the oil for my V12 DB9.

£25 or so for 4 litres at costco

It needs to be fully synthetic 0W-40 oil.
I use Mobil 1 - which is Aston's brand of choice for V12's... also officially recommended for most Porkers!
