do a google (if you are capable) on the chemical makeup of octane and see how
many oxygen atoms you find.
Or you could look up the octane rating of methanol (about 100 on the
(R+M)/2 scale) and its chemical formula (CH3OH) and note that a liquid
fuel with a high octane rating can have as many oxygens as carbons.
The octane number on the pump does not tell you how much "real octane"
is in the gasoline. Extra credit exercise: look up octane numbers for
"normal octane", "normal heptane" and "iso-octane" (a.k.a.
2,2,4-trimethyl pentane).
