If you can find a Jet station nearby, I can recommend their LRP - the
performance is insignificantly different from 4Star in my Spit.

Thanks, Bill. So ordinary unleaded actually gives better performance
than LRP? That surprises me, as I thought LRP *was* unleaded (plus
some (alternative) anti-knocking additives).

Makes sense. Several other people have commented (off-list) that
unleaded is the way to go, so I will try half a tank of Optimax and see
what happens.

I have a bottle of this jollop in the boot - I put it in there a couple
of years ago, just in case I ever found myself unable to obtain 4Star. I
have never used it.
