Re: Higher octane??

["Gary H." <62to65mopar@xxxxxxxxxxx>]

Any pinging or spark knock? 

>From a BP document:  Increased octane does not increase power.

Higher compression and improved engine breathing will increase power.
These modifications may lead to detonation or combustion knock which is
then eliminated by using fuel with a higher octane.
