Is it necessary to change from water cooling to oil cooling for cars?

[McDante]

It is not necessary to change from water cooling to oil cooling for cars, and the reasons are as follows: Currently, there are three main types of coolant used in cars: ethylene glycol antifreeze, waterless antifreeze, and cooling oil. The vast majority of cars use ethylene glycol antifreeze because it is cost-effective and performs well, making it widely adopted. If you switch to oil cooling, the first issue is the higher cost, and for ordinary cars, it is unnecessary. Unless there are specific cooling requirements, there is no need to make the change.
