Murphy USA in Mason City (4059 4th Street Sw)

Yes, they have diesel. Look for the green post...that is how all Murphys mark the diesel pump so you know how to approach.

Nice station and has E-15, E-85 and 93 octane!!!!

Not a bad little station. Us a Wal-Mart gift card or Wal-Mart credit card for fuel discounts. be warned some local will consistently report the prices in the incorrect slot (regular in mid-grade space and so on) be sure to check other fuel types lists sometimes

Great gas price

Awesome

great station. low prices

Good station clean and has 93 octane which is a huge plus right n my book!!

Low prices on gas and tobacco

its nice
