Well I did a search on this and only found post that just mentioned it but really said nothing about it. I would like to know how people feel about 0w30 motor oil. I have never used it, but I am seeing it more and more on the shelves. I do my own oil and know my way around cars so I would just like some opinions on how it will work if at all on the cobalt SS super charged.

 

I would stay with the 5w30. Its light enuff for power yet it will last and best of all it dosnt voide the warrenty.

And the computers oil life thing is calabrated for it to so I would use that.

later

 

Stick with the 5W30 Mobile One

 

I see you're in Texas. That means 0W30 is a waste of money for you. To put it simply, the 0, 5 or 10 that comes before the 30 indicate how well the oil will flow when cold. 5w30 stays liquid down to -32c (-26f)and 10w30 stays liquid down to -18c (0 farenheit).

0w30 is made for harsher winter climates.
