I got hold of the 2015 Australia recommended oils page awhile back. Chart is actually for the FJ.
The Middle East is different still, sorry don't have the chart.
15w-40 down to -12C / 10F
10w-30 down to -18C / 0F
5w-30 for 10C / 50F or LESS
I am currently running 5w-30 with zero issues and will be trying some 5w-40 and 15w-40 down the road a bit.

I'm running a 30 weight as well and the engine is smooth as butter! Did you ever run a 40 weight?
