<VV> Pinging Question

[FrankCB at aol.com]

Tony,
Not only will retarding the spark usually cause the engine to run hotter,  
it will also REDUCE your gas mileage.  So saving 5 to 7% on the cost of a  
gallon of gas is a loser if it REDUCES your gas mileage by 10%.

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.
