For day to day use the 10w has the edge as it is has the better cold start.
So if you like a good 10w-50 is more street friendly then a 15w-50.

Ahhh, you're a fountain of knowledge mate... Cheers.
Well whenever I drive my Sapphire I always let it get up to full temperature before I move or drive it anywhere.
Would that mean that in my case I'd be better off with 15w-50 mate?
