Jim, your "testing" was the same as my observations from the previous year, except that I bought a case of the MaxLead and tried two different brands of "racing fuel". In no scientific community, heck, not even in junior high, would that qualify as "scientific method". Not mine, not yours.

If the same tests were performed with documentable, reproducible, measurable OBJECTIVE results such as those obtained on a chassis or engine dyno, they would be better received and would provide useful information.

It is important to test for one and only one variable at a time. For instance, baseline the car/engine as is with a fuel of a known grade. Then tune for maxiumum output without detonation. Record temperatures and timing curve. Change ONE element and record the effect. Alter the profile to better the output, or go back to the previous profile and try another variable.

You've also pointed out before that your car is stock "except for the pistons". That one minor variable won't change in your own personal assessments, but that means that I cannot compare your results to my results. There may be other minor things under your hood, like HEI, to alter the formula.

If anyone is looking for a miracle in a bottle of MaxLead, they're not going to find it. That said, I still add a quart to every tank because it DOES give valve recession protection.
