Sierra club published a list of which Gas companies are better than others and reasons for that.
The environment record is a good reason to decide where to fill up gas from. Till now for me, location or credit card acceptance use to be the primary reason, but not any more. So, no more filling up gas at 76, I will be trying Arco and others.
Here is the summary list with links to Google’s local US search, just add your location.
