yep. Although, given that it's regularly 15 cents/gallon cheaper than
other gas, I don't think I'd waste my time spending a few months
tracking the Hess gas cost/mile.

There's a reason it's cheaper. The fuel company in question has made a
marketing decision to appeal to those too dumb to understand anything
beyond "look, it costs 15 cents/gallon less to buy!".
