At what ambient (high) temp would u recommend syn?

Short of desert racing across the sahara, I don't think you can ever recommend syn for "just heat".
Almost every passenger car will have a cooling system that easily keeps things reasonable enough for any OEM compatible fluid.
If your vehicle gets hot enough to start cooking dino and not synthetic, in a passenger car at least, you have BIG problems...
Turbochargers are probably the one "heat point" synthetics really start to shine in, but even air cooled bikes run fine on dino.

You would use synthetic for extreme cold ambient temps, not high ambient temps.

+1 - ambient heat should not be the grounding choice to use a synthetic.

Eugene OR will never experience ambient temp extremes (low or high) that makes the question relevant to your location.
The above replies re: turbos and low temp extremes are spot on!

The oil in the engine will always be much hotter than the ambient temperature, at least on earth. As you move closer to the sun, things change.
+1 on the cold ambient temp being the deciding factor.

Ambient temp has little effect on oil temp unless you're racing.
After umpteen jillion oil changes, I can guaranty you that ambient temps have a big effect on oil temp. Oil is about 1/2 your cooling, BTW.
Viscosity is what counts for high oil temps, not whether it is full synth or not.
That said, Turbos can get very high temps in isolated spots at full throttle. A full synth makes sense in turbos to me.

0
degrees.
The cheap stuff like SuperSyn. In a jug. $5

Dino's begin to oxidize rapidly as oil temp's approach 130C.
Ambient temp's can affect oil temp's, but the main driver is how hard the vehicle is being used with sustained WOT to drive the oil temp's that high and even then it's very much vehicle specific whether you can get the oil temp's that high ever.
