[Healeys] octane needs for 2006 Mini Cooper S

[Curt/Nancy Arndt]

Jack,

I have an '06 Cooper S and by mistake put regular 87 octane in instead of
91.  The car almost immediately started to ping anytime I put even a
moderate load on the engine.  I immediately went back to premium fuel.

Purchased the car new on Oct of '06 and have 20K miles on it now with no
problems.

Cheers
