I've always used premium fuel (as recommended), but have been told that Giant Eagle's Get Go gas is inferior & can cause catalytic converter failure.
If this is true, what would be the approximate cost of that part (not counting labor)? Their comment was based on a "lean" smell to the exhaust. Is there a hook up spot to get a computer diagnosis code?
What can be checked when there is a drain on a new battery? It will start if done every day but won't start if it sits for 2 days. No lights are left on & radio & auto air/heat is off. Under hood light has been disconnected.
