I personally notice mild seat-of-pants non-scientific improvement in uphill
performance when running 93 Octane, but probably only because I am running
advanced timing on my '85 Westy.  I don't think the WBX has high enough
compression to use the higher-grade fuel to its full advantage, so I run
regular most of the time and can still cruise at 80 on a flat road with some
breathing room left.
