Does the octane of gas used affect the amount of carbon monoxide created?

Answer 1

No. The carbon monoxyde (as opposed to carbon dioxyde) is the sign of incomplete combustion, and the catalytic converters are supposed to take care of converting that to CO2 (carbon dioxyde).

Now then, perhps you meant carbon dioxyde, which is the result of the combustion of anything that has carbon in it?
Again here, the answer is no. There is just about as much carbon in high octane gas as in regular. The octane rating results from the additon of special compounds in minute quantity, as well as the presence of more havily reticulated molecules (octane is actually tri-methyl-2-2-4-pentane, a molecule that looks like a tree with branches sticking out). It is the presence of this complex structure that makes high octane gas capable of better resisting pre-detonation. But in the end, they just put as much CO2 out as regular gas. Unless the high octane allows you to reduce your gas consuption (a car meant for high octane that is forced use low octane gas has to run rich to prevent knocking, so you end up using more gas as a result, and then you can have more CO2 produced).

Answer 2

yea. higher octane equals more effiency
causing
lesser Carbon Monoxide Production

Answer 3

High octane fuels undergo more complete combustion under he same conditions and hence give off lesser CO.

Answer 4

Yes it does.higher Octane is more effecient.

higher effecientcy, means less CO.

BP

Answer 5

cleaner burning fuel emits less carbomonixide
