Well, BP near me are calling what they have 93 octane though sometimes I suspect we are all getting crap gas! Seems like lately I've read more posts about stalling and poor performance in other parts of the board than ever before. Hell I dunno </conspiracy theory> Annnnyway, have not tried Shell, I'll have to see if I can find it!
