<VV> Oil temp

[Joel McGregor]

If he is going to be comparing temperatures then he needs to either stay consistent or specify that he's talking about 2 different things.  If engine temp isn't talking about coolant temp then what is it talking about?  Actual engine temps will vary widely depending on where you take it.  Exhaust port temp won't be anything like the crank temp.  If engine temp isn't coolant temp it's meaningless without specifying where it is taken.
He also claims "Smog equipment and computerized combustion control favor a 'hotter' running engine."  This is a false generalization for "smog equipment"  he would have to specify what he means by "computerized combustion control" to know if that is accurate.  What does a "hotter" running engine mean?  Engine, coolant, oil, combustion, or other temp?  Elaborate systems to lower combustion temps are part of most emission control systems.

Contradict? Not really. At first he gives a range of modern engine temps, then cites a specific example, then gives a second general range operating range.
Keep in mind that just because a thermostat opens at say 195 F, that is not the temp the engine IS. It is only the temp the thermostat opens at, to begin cooling. The higher the pressure in the system, the higher the temperature will be.

Average engine temp (as no specific given) would be around 195 - 205 degrees.
The normal operating temperature for a modern (e.g., 1996+) automobile engine, manufactured for sale or use in the US, will fall between 200 and 250 degrees F
These 2 statement contradict.
