The shell stations are having a problem with a high sulfer content in their gas. They shut down several stations because of this but alot of them are selling only premium which seems unaffected by this for the price of regular (1.93). Alot of the shell stations are doing this so keep and eye out for it.
I'd say that the premium is fine or they wouldn't sell it and being that alot of us have performance cars we run premo and this saves us 20 cents a gallon if not more.
The one of eastbay in largo has it cheap and the one off missouri/rosery both have this going on here in largo. Happy pumping
