OK,
A comment from the "I stayed at a Holiday Inn" sort of guy. I have always heard that leaded gas was better for older motors from the pre-catalytic converter days because the lead somehow helped preserve the valves, valve guides etc. I don't know how the unleaded based motors overcame this. I fully agree that we should be able to run either one based on how which we "believe" our motors run best on. I fully believe that my 25 year old pushrod, carburated IT motor ran much better, with less valvetrain noise, using 103 octane leaded fuel. I don't know anything about the chemistry, combustion, physics, or mechanics of why I have had better luck with race fuel. I just know my motor "felt" like it ran better. I also know that I may be full of crap. Bottom line, we need to come up w/ a more comprehensive way of testing that is fair to all.
On the performance enhancing additives (I.E. proplyene oxide etc..I live near the Kennedy Space Center) unfortunately the type of people that would use crap like that probably don't give a damn about it's cancer causing effects..either on themselves, or those around them. It's sad, but likely true, and we need to find a way to eliminate that hazard on a permanant basis, as my eyebrows burn off after following them.
I must admit that it is less of a problem now than it was a few years ago.
Thanks to all who are testing, and providing usefull information about this. We all don't want to keep doing what we think is legal, and being penalized by faulty testing methods.
