We're seeing this in Massachusetts too. Must be a new federal regulation in terms of listing it at the pump.

 

Just did a google search... Came up with this. I fell asleep after the first line.

Does look like regs, although perhaps nothing new. Maybe the feds are starting to enforce it, although this example seems to be a state (CT) recommendation?
