E450 V10?
06' just hit 33,000. Sat all winter, oil changed a few weeks ago. Noticed a ping, chirp, sound, etc? from engine while on recent trip. All gauges were good and ran strong. Put some 93 octane in. Will ...

Nice to see that the myth of using higher octane to solve mechanical problems is still alive. :S
30+ years of automotive engineering disagrees with you.
I qualified my response by saying "ping" from pre-ignition can be cured by higher octane. Why the pre-ignition is occurring is hard to diagnose, but likely it is from carbon build up inside the combustion chamber.
Higher octane fuel will not ignite until a higher in cylinder temperature is reached, such as an actual spark event nor just a "hot spot".
In my case, anecdotal evidence proves I am correct.
Nice job cherry picking my quote. "Ping" in a V-10, if in fact that is the problem, is not caused by running 87 octane gas. The V-10 was designed and engineered to run perfectly on 87 and running 93 is merely a waste of money misdirected at a problem that has not been addressed. The source of the problem needs to be identified and dealt with and buying 93 octane gas is at best a band aid solution. Like I said, Google it.
I did and here is an interesting article by a Ford engineer on the real impact of using the wrong octane:

As always... Opinions and YMMV.
