You all pay over two bucks for premium? I guess I should feel lucky. In Texas, the high price around is $1.69. I found a "Generic Brand" place that sells premium for $1.38 but now an Exxon is charging $1.37.
I think you might be right that they all buy their fuel from the same sources. This morning, I saw a tank truck leaving the Exxon station and it didn't say Exxon on it.
Maybe they're pulling a fast one. But, it's a brand new "Tiger Mart". Anyway, I don't think I'd better complain.
BTW, my 300SE runs fine on either brand.
