Murphy USA opened up a new location in Floresville Texas before the Easter weekend and now there is a gas war between H.E.B. and Murphy USA the price for a gallon of unleaded is now at $ 3.38 a gallon and diesel was at $ 3.53 a gallon.  There is no telling on how long this gas war will last but in my opinion Murphy USA part of the Walmart group has much deeper pockets than H.E.B.
