[Mgs] Sunday morning, a bit OT

[PaulHunt73]

If local law insists they add ethanol to a certain proportion, which has the side-effect of increasing octane, why would they continue using some other octane-boosting constituent?  In fact surely they would have no choice but to reduce or eliminate it in order to maintain a given octane.  Unless they let the octane rise several points but market it as lower octane and sell it at that lower octane price ...

  The skeptical and distrusting scientist in me wants to believe that petrol manufacturers are using the ethanol content to elevate the effective octane rating thereby saving the other octane boosting stuff, whatever it is.
