What is so special about OEM coolant? Isn't the thing that is important the ethylene glycol content? Does OEM coolant have some special properties not found in non-OEM coolant?

Some aftermarket coolants use silicates in the mixture. Hondas use alloy blocks and silicate-containing coolant should not be used in them as it corrodes the water pump. OEM coolant is the only suggestion. Another one that might work is water wetter.
