Key word for a young member....thermo/molecular break down characteristic between normal oil and full synthetic. One comes out sludged the other comes out blacken but still viscious.

which one will most likely resist heat changes (endothermic reaction) under hard abuse. Have you actually looked at the difference in oil thickness between the two oil types. this is why I switch both of my turbo cars to full synthetic for added protection. the turbo will cook normal oil into chunks.

the water/antifreeze exaples should have been better presented. It was an example to demonstrate the effects of engine cooling between the types of fluids.
