That's still the way it seems to work today.    If I don't run 
premium in the 110 I drive daily, it pings.   I'm not real keen on 
backing off the timing to stop the pinging since it can cause the 
engine to run a little hotter than usual... in summer this isn't 
good.  I pay the extra dime/gallon and run premium.


Except Citgo premium... which seems to ping anyway.
