This is a brand new service station. It is clean and well lit. There is no car wash. Right now $2.28 is an introductory price, mo idea how long it will last, but is cheapest gas in 2 counties.

Sometimes there credit and debit won't work on machines so you can't get gas. It's annoying but they usually have the cheapest gas

Worlds slowest diesel on pump 1 and it sprays when done. Ugh... otherwise an easy stop for a big RV with a tow car.

was pretty upset to find they were displaying gas cheaper on the sign than what was at the pump itself. It's an electronic sign at that...
