So I converted my 03 Neon to green coolant

I underestand doing what ya have to sometime to get by, but ya wouldn't change your oil and put water in cause you didn't have oil would ya? I know coolant seems like it doesn't matter, but they all have chemical differences. I'm just saying that later on after the green breaks down and clogs up coolant passages and wears out water pump from the inside it would be easier to just use the right stuff.
