Wow, real mature.I thought your couldn't say that on a family forum.

hot anti freeze is worse than hot oil.
Over the years I've had two friends go to the emergency room from engine coolant burns.Umm no.
Just as an FYI, the heat capacity of water at 77 Deg F is approximately 1 Cp. The heat capacity of motor oil at 77 Deg F is approximately 0.45 Cp Therefore a water antifreeze solution holds more heat than motor oil at a given temperature. It's the amount of heat and not the temperature that determines how bad a burn is.Over the years I've had two friends go to the emergency room fr55om engine coolant burns.
OTOH I know of no one going to the ER for motor oil burns.
That second friend to the ER, the incident happened after the engine had been cooling for nearly an hour.
What about the difference in adhesion between the two? Spill some hot coolant on your arm and you can wipe it off in less than a second on your shirt before it does much damage. Oil will stick to your skin much more.Just as an FYI, the heat capacity of water at 77 Deg F is approximately 1 Cp.

Lost more heat to your skin if it's on there longer, no?I would think that by the time one gets the oil wiped off relative to the time it takes to get hot coolant off, the oil will have lost more heat than the coolant solution and therefor make for a less severe encounter.
Isn't oil denser than coolant?Remember, the amount of oil left behind on skin will weigh less than a similar amount of coolant on skin, and therefore have less heat to transfer.
That's kinda like changing the oil filter only every OTHER oil change. Why would you drain and refill the coolant when it's "half worn" at say 50,000 miles instead of changing it all at 100K? "Half worn" still protects as well as new.To me, if I drain half and refill, but do so when the coolant is say “half worn”, then the coolant is now mostly new (75% good) once again. Sure I could drain the block and do a flush, but to what gain?
Less work than messing with a block drain. I pay a bit more but do less work. Even trade in my eyes.That's kinda like changing the oil filter only every OTHER oil change.

Coolant could turn to steam when pressure releases. Also, there's much more energy in 200F coolant than in 200F oil. About 50% more.Umm no. Motor oil temperatures can reach over 300 degrees. Coolant maybe 250 and just when under pressure, maybe 230 outside the cooling system. Of course you, wait 10 or 20 minutes if the engine is hot before changing it. And wear gloves. Do you change your oil cold too?....Wait, better not answer that.
