I finally used my Safeway discount to get 10 cents off per gallon. The Mobil after discount price was 2 cents cheaper than Valero.
What is the average discount I should expect?
I wouldn't want to go on a long road trip in my truck -- CNG refueling stations are still a rare thing. But as a daily commuter, I don't see why EVERYONE isn't doing this. The total operational cost of the vehicle is less than half that of a gasoline engine. Repeat, less than half. Furthermore, the emissions are cleaner than the air we're currently breathing..
But as of yet, for some reason it has not become practical for the ordinary consumer.
That isn't much of a downside considering the advantages.
Like I said, I am in favor of CNG, but for most people it's still not a practical solution. I wish it was and maybe someday it will be, but as of yet, it's a niche market.
Many of these offers seem NOT to be usable in the Northeast
