Hey, all!
When is everyone changing their oil....when OnStar says to, or sooner??
With other cars I used to change my oil every 3K miles religiously, but I've been stretching out the oil changes since getting the H3. Those monthly emails from OnStar make it sound like I can drive forever before needing to change the oil.
Is that GM's way of getting you to screw up the engine so ya have to buy a new car sooner??
