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).

dood, rather poor googling on your part. "octane", a physical fact, and
"octane rating", a concept, are not hardly the same thing.

That is just what I implied, and that is exactly why looking up the
chemical makeup of octane will not tell you how much oxygen is in
gasoline.

So for the benefit of others less educated, do you know the octane
rating of normal octane?

jaxashby tells the world that his contribution to this ng is the same
as the octane rating of normal octane, that is, less than zero.

the octane rating of normal octane, ... is, less than zero.

That is correct. Less than zero. Less than the rating assigned to
normal heptane.

I gave you a big hint when I said to look up octane numbers for
"normal octane", "normal heptane" and "iso-octane" (a.k.a.
2,2,4-trimethyl pentane).

Here's another hint (in form of questions): which is better as diesel
fuel, octane or cetane? Which has higher octane number, heptane or
propane? Can we make any generalizations about long vs. short chain
alkanes and their branched isomers?
