Hi, everyone! First-time poster. I am a proud Cruze owner. 2014 1.8 LS (non-turbo). I'm just outside my factory warranty period and had to go purchase my first oil change (dealer did them twice per year for free prior to this). I didn't pay any attention to the type of oil they were using, and when I read my receipt a few hours later I noticed that they used 5W-30 conventional. I know my manual calls for semi-synth. My question is, can my engine "live" for 3,000 on this oil, or should I go get it re-done? I know that the turbo engines require full synth, but since I'm not turbo I'm wondering if I can just live with it then switch back to the "correct" Dexos blend at next change.
