and this is your claim:

I hold a mechanical engineering degree, have been employed in the profession for 23 years and have read quite a bit about the combustion process and fuel.

Time and time again, objective evidence proves my point. In fact, the article below noted that the car designed to run on 87 octane actually ran WORSE on premium. That is not the first time I've seen that happen. I suspect that premium's slightly slower burn time might result in compromised combustion in some engines that are designed for regular fuel.

"Don't use premium fuel if you don't have to. If your car specifies regular fuel, don't buy premium under the mistaken belief that your engine will run better. The only difference you'll see is about 20 cents more per gallon. Most cars are designed to run just fine on regular gasoline. Even many cars for which premium is recommended will run well on regular. We have found that the differences are imperceptible during normal driving. Check your owner's manual to find out if your engine really requires premium or if you can run on other grades."

I have nothing to "Teach" anyone on this board.

Rather, I prefer to ignore children who have no understanding of the related science and will therefore remove myself from this thread.
