whats the best station and octane. 91 or higher right? i was reading the manual and it says dont use gas wit MMT and any that have more than 10% ethanol.
my cars got 200 miles. should i be diligent on the oil levels and the coolant . or is that just a every time i gas up the car thing? any other recomendations on keeping the motor clean and what oil is the best for our SS/SC? thanks guys! sorry im such a nooob, i feel like i gave birth way too paranoid =*(

 

I always use sunoco 94 and everything runs good

 

Everything will always run better on hightest gas with the cobalt.
