Max, it seems that way, don't it.
But when you consider the advantages vs. cost, it makes sense.
Advantage #1: 500,000 Mile service interval. That's right, Five hundred thousand miles.
Advantage#2: Lower cooling system pressure. This is beneficial to the cooling system (for obvious reasons). I've taken the overflow bottle cap off at 210F, and all I hear was a little hiss. No steam, no drama.
Advantage #3: Quicker heat transfer. The problem with Water based coolants is not the water... it's the layer of steam that develops when the water in the coolant comes into contact with hot engine parts such as cylinder walls. Steam does not make a good thermal transfer vehicle.
Because Evans' does not contain any water, (hence the company recommending less than 2% of old water/coolant left in the system before adding their product), it will not suffer from the vapor effect.
I've had the coolant up to 235F pulling heavy loads in my diesel pick-up trucks. Oil temps only climbed to 215-220. Granted, I run heavy duty oil coolers in them, but I could have gone even hotter on the coolant... at least until the oil would have started breaking down at around 245F.
However, the interesting part about these temperatures is that I could not get the coolant over 235F no matter how hard I tried. My EGT Temps are usually sitting right at 1300F and as soon at I crest a big hill, within 1/2 to 1 mile the temps are back to normal operating range. Which kind of depends on ambient temperature a bit, it seems. In the winter time, I'm looking at 190F and summer about 200F.
So, in a nutshell... yeah. It's worth it.
