Oil Life System
Hey, I have a 2009 Cobalt LS XFE Coupe with Mobil 1 non-synthetic and I'm still confused about when I should change my oil. The manual says that the car will tell me when (25%), so I decided to change it around 50% instead. The manual does not tell me to change it around 3000 like all sales associates tell me to. My oil life meter says 59% and a little over 5000 miles as of today since my last oil change. Should I still just change it when it gets to 50% or do the 5000 mile thing? Also, should I switch to synthetic?
