Hello I'm Cheran... Dear Mr Scotty... I brought 2008 Chevy Cobalt just want to know which coolant oil shall I use ???? is it the green or orange... if you know a good brand for Chevy 2008 Cobalt please message me ....and I went to my mechanic to change my engine oil he said that it's more than a thousand miles you should put 10 W 30... but in the book it says 5w 30... which is good...

color means nothing, you use long life coolant from any manufacturer. The ones that say Long life coolant for ALL cars. I would use 10 30, those are known to burn oil as they age
