[T3] 73 T-3 oil temp?

I just have VDO gauges oil pressure and oil temp. I know they are not dead
accurate . Yesterday I got stuck in traffic because of a parade . The oil
temps driving to my destination never got over 180F . Yet on the way back I
was stuck in traffic barely moving for over an hour and the oil temp read
just under 220 F the oil light would go on at idle , it was 94 F air temp .
If I put the auto trans in neutral the oil light would go out . I checked
the oil level later and was down 1/2 quart . Once I was able to start
moving the oil temps dropped .

 My question is since at idle the cooling fan is not moving much air plus
the 94 F was probably higher because of all the traffic other cars generate

 I've never had this happen before being stuck just the engine idling for
so long. I've had this oil light on after a freeway run on a hot day came
to a stop the oil light would be on then as soon as I hit the throttle it
went out.

 Is it just that the cooling fan at idle is running slow the reason the oil
temp would climb? Because the temps did drop back down to about  190F once
I was moving yet I didn't get to drive far enough to cool it back down to
180 F where it normally is. I would also place it neutral when this
happened to get not only the voltage to stay up it's 1,000 RPM in neutral
and 850 RPM in drive plus hoping the extra RPM would help bring the temps
down. It didn't, I had to be moving at least 35 MPH and kept it in 2nd gear
so the RPM's were about 2400 RPM.
