OZ LC Oil Visc. Chart

Now I don't want to here anymore 20w-50 threads saying "its to thick for the 1fz!!!"

It says at bottom of pic/page
* On engines with turbo chargers, never use above above 0 C (32 F)
That is on the Diesel chart for 5w-30.

Would that be the same for turbo or supercharged 1fz's?

How does synthetic oil fit in the chart? Can you run a thinner oil if its syn when its hot?

Also, why does the chart say 10w30 up to 100+ and 15w40 and 20w50 to 100+? How do you know if you need the
30, 40 or 50w if they all go to 100+?
