I'm sure other RS-ers also know about this -- be apparently, the Mobil station at Richmond Superstore carries these options now...
I don't see it at any other Esso / Mobil stations yet, but it wouldn't make too much sense if the option is only offered in Richmond, but not elsewhere in Metro Vancouver.
We need a 3-way Shell 93 vs Chevron 94 vs Esso 93 battle real soon, esp given how Chevron 94 is now an ethanol blend instead of "pure gas".
