I figured I'd post this here since there's more diesel MLs than diesel E's. I've found 47 Cetane at one station in Tysons near DC (BP by 123_ , but it's literally 40 cents more than 40 Cetane everywhere else. I'm worried that they charge that price because they're the only high cetane diesel in the area. Does anyone have any alternatives? If I'm paying 40 cents more, I'd like to be getting at least 50 Cetane or maybe 55...

Anyone with tips on High Cetane near NOVA?
