General   (General discussion, talk about anything.)

Engine oil, gearbox oil and brake fluid are totally different to cooling water

Gosh really???

Besides.......dont you mean engine coolant?

I think the difference is you understand exactly what purpose oil and brake fluid do, however you fail to understand exactly what engine coolant does in addition to cooling and furthermore refuse to accept just how critical its makeup is and why it has to be used in modern engines.

Am I right?
