I don't think that's entirely true Wade.

Pre-Ignition and Detonation are 2 different occurrences.

Pre-ignition like you said is before the spark, and almost always destroys the motor.

Detonation happens after the spark, and most motors (<1.5hp per cui) can live with a little detonation.

O.K. Ican go along with what Johnny said.

I dont claim to know it all. I do not know the difference between pre-ing and detonation. I'm fairly sure what im thinking of is detonation. I know that the meaning of octain is the burn rate. and det happens because the gas ignites before the plug fires. Like a desiel ing.
witch is why the call it desieling. higher octain has a slower burn rate. witch keeps it from detonating. because it does not have time to. It is
also the reson why higher octain will slow a car down if it does not need
it. It will not burn all of the fuel because of the slower burn rate. Less
boom.

I havent looked around all whole lot at this but I havent seen a price.
how mutch is it. Thank you for your time. Wade
