I'm having a nifty time thinking about antiknock agents with adjustable properties that way the delay is tuned to the rpm of the engine giving slightly higher mileage

Fe(CO)5 is the archetypal fluxional molecule due to the rapid interchange of the axial and equatorial CO groups via the Berry mechanism on the NMR timescale. Consequently, the13C NMR spectrum exhibits only one signal due to the rapid interchange between nonequivalent CO sites.

suggests that a version of Fe(CO)5 like FeC-(adjustable)(CO)4 where one of the points on the molecule had an adjustable ligand could affect the entire molecule geometry to have different effects I was thinking photocatalysis n was pleased to read Photolysis of Fe(CO)5 produces Fe2(CO)9, a yellow-orange solid, also described by Mond Thus zapping Fe(CO)5 with light is demonstrated to create a near compound with different antiknock properties

the idea is that either the gas pump guesses what kind of car you have then pumps fuel with a modified antiknock compound blend better for low rev city driving or high rev distance driving perhaps better would be a xenon lamp that zapped generic fuel at either the tank or through a transparent tube to convert some of the antiknock compound to a better tuned antiknock compound

Ethanol?

It fulfills a number of goals and is perhaps not primarily an octane-booster, but the ethanol in E10 gas is an important oxygenate and does help prevent knock. Should ethanol be mentioned in this article?

Antiknock agents

I think there's an error in the article. Toluene and 2,2,4-Trimethylpentane aren't exactly anti-knock agents, they are fuels with a high octane number. AFAIK, fuels with a high octane number increase the octane number of the mixture proportionally to their volume (or mass), but anti-knock agents increase the octane number far more than the proportion in the mixture.
