A 10w40 is the same thickness when cold as a 10w60.
e.g. Multigrade oils work like this for example with a 10w60
the oil has the same viscocity as a 10 wieght when cold, i.e. thin and slippery but when the oil gets hot, it has the same viscocity as a 60 wieght, thicker for more protection.
The oil is thicker when its cold but it has the same protection as a thinner 10 wieght
The oil is thinner when it hot but has the same protection as a thicker 60 wieght
Its wonderfull stuff
10w60 is a better oil, the only thing you have to watch for is when the oil is hot, even though it has the properties of a 60 wieght, it is very thin which can cause low oil pressure. No oil will protect your engine if you have no oil pressure.
At 40k miles, I wouldn't worry to much about that, 10w60 would be ok but most people swear by Mobil 1.
I use Mobil 0-40w Fully Synthetic in my 02 STi with 40k and had no problems.
Hope that helps.
