What octane fuel gives more emissions

[craig2003]

As above, are your emissions worse using V Power, Tesco 99 whatever they call it, 97 or the council 95 ron?

I don't think it would? All the octane difference means is the point at which detonation occurs.

[craig2003]

I was wondering if anyone on here had actually measured the differences?

Who would have the kit needed to do such a test?

Depends which emissions I imagine, since the chemical composition is different.
