Although from my earlier commentary you could assume Mobil 1 0W-50 to have a lower
zinc content it does not and it does have the 50 weight viscosity which is comparably as important in a high powered engine that the owner chooses to flex the muscles of from time to time.
Below is Mobil 1's representation of
zinc levels they provide in various products they offer.
The other
oil that fits into this category is the Castrol 10W-60 SuperCar Lubricant.
which is targeted at high end Euro supercars. I could have sworn I had purchased a 0W-60 version of the
oil in the past but if I did, I can't find it today. In any event the 10W-60 alternative from Castrol is functionally similar but a little more viscous at lower temperatures.
Both choices and similar competitive offerings should serve most Cobra owners with high output engines quite well.
