This critical point is glossed over by the manufacturer and most of the hokey celebrity endorsements.

Not at all.
Putting aside that our cars have 'dumb' coolant temp gauges and cannot be used to measure any change in system behaviour, the actual coolant temp would remain constant until such time as the thermostat ran out of authority.
None of us know how much margin the S-types have. Avos' experiment indicate that it's sufficient to deal with the conditions so far.

But even if you would monitor the actual temp, you wouldn’t see much difference; at least I haven’t really noticed something till now. Temps are as it used to be when driving.
As said before I think the hardest conditions are traffic jams with airco on and hot ambient temps. Here also the engine turns the slowest meaning low coolant flow, and hot air also gets sucked in again from the front. But even then, the fans will kick in (just as it did when I had the stock coolant), so no real effect. It’s getting warmer here now, so let’s see how it develops, but based on what I have seen so far, I do not expect any issues here at all. For hot climates I would expect more of a difference, but also than based on what I have experienced so far, I wouldn’t expect any major temp differences there, worst scenario is only that the fans kick in more often. With the STR it’s even less noticeable as the fan speed is controlled based on the coolant temp, where on my car, once it hits 97 the 2 small fans will both turn on at full speed.
Have just checked today the water content, and it is still around 0.5%.

ME! i have used Evans coolant since 1989, in three cars!
1st a 7.4L BBC(big block chevy) Camaro. yes a learning curve.
2nd Turbocharged Mazda rotary (500whp from 1.3L)2700lbs, try that in your spare time! i had it in the Mazda for 11 years, and added maybe 1/2 gallon, it was drained and reused at least 3 times, so topping up was requeired, it turns a slight amber color over time, BUT never had any internal corrosin or water pump problems like pitting of impeller(cavitation) or leaks. at the time no improved pump was available(higher pressure pump) so i made my own from BRONZE, a modified diesel engine impeller
same hoses when originally assembled, and i used a LOW pressure cap, measured around 5-7lbs with a gage.
and now in my 1978 Jag V12 , i dont experience any hi temps, or any problems if you understand and follow instructions of how it should be used!

Just a small but positive update:
So far all is working fine, am very pleased with the setup, wish I had done it earlier with regards to the toxicity of the original coolant which I have been in contact with now and then.
I have had already some hotter days (80 degrees) combined with hard driving (so long drive, traffic jam, airco on etc), and there the hottest the coolant got was 217 degrees. I did indeed see an average rise with the higher outside temps, but to be honest I can’t remember what I had before under these conditions with the oat coolant. I use a large intercooler radiator which lowers the airflow a bit, so my setup is tougher on the engine radiator then stock cars.

I think that the Evans is going to be perfect for my car. It is 12 years old, has 7,300 miles on it and all it's original hoses. How? you may ask. Well, it's been in an air conditioned garage for 12 years and driven occasionally to car shows. The fluids get changed regularly. With Evens, I likely will not have to worry about the cooling system for another 12 years. Jay Leno is putting in his Duesenberg which is worth more than 99% of the houses in the US. I think that's enough for me. That and other respected members of the forums' recommendations. Call me Joe Friday - Just the facts, ma'am.
