As of last week, there's been reports that Shell is now receiving 93 octane and slowly changing all their stations to carry it.
They're replacing the 89 with 91, and 91 with 93.
The 93 contains ethanol and so far with limited testing, people are claiming it's way better than Chev94 and at least comparable with 92 down in the States.
For anyone tuning their cars, this should be a game changer.
