There are lots of ways to get detonation (preignition) but this is not one of them. Higher octane is used to prevent detonation, that is why race gas is higher octane than what you buy at your local station.

The compression ration in your v-6 is too low to combust premium fuel completely.
The V6 runs HIGHER compression than the LS3 and L99 V8s. That's a very easy thing look up!

Running premium fuel will cause your ECU to pull timing because it is knocking.
Wrong, the ECU pulls timing when it sees (hears) knock. You get less knock with higher octane gas.

Quote:
You will not feel this or hear this knock.
This is the only correct statement in the whole post and it assumes the knock sensors are working correctly.

This will also cause greater carbon build up in your combustion chamber.
What are you basing this on?
