Think you will find the old AVGAS is a less evil thing than modern ULP or worse still the 95 or 98 PULP. The ethanol 95 PULP is less bad, but no good in aviation of course.
No hype or BS......just do the research. A PHD industrial chemist friend of mine explained this to me many years ago, he was in the know......I just understood most of what he said, enough to know that what CC refers to is pretty much correct.
Besides my plane and race car and my brothers Katana love the AVjuice....and hate the PULP!
