Semi-Synthetic oil for '10 Cobalt LS

[AmyF]

I have 13,000 miles on my '10 Cobalt LS. I was going to try the semi-synthetic oil for my upcoming oil change. Anyone else use it? What are your thoughts? Is it better to go full synthetic? From what I understand, semi-synthetic is basically in between regular and full synthetic. I drive a LOT - appx 125 miles a day basically.

Mobil 1 isnt a full synthetic (I know it says so) Cobalt Tom has more info on this. That said its the only oil to touch my motor since I bought it 27260 miles ago.
