Here in Mass gas in no name stations are running around $2.05 per gallon, a lot less @ BJ's, while in big name stations are 15 to 20 cents higher. Feels good at low cost gas when filling a 80 gallon ...
I've been buying the cheapest fuel in the area my whole life, what include high-performance luxury cars as well. The only problem I had with fuel was over 20 years ago, at the time when stations had single wall underground tanks. One time I suck rusty water with fuel and had to drain tank. I buy the cheapest fuel but am trying to avoid stations with little traffic. Costco in CA usually is having the lowest prices and there is always long waiting line.
