Octane Rating and Mixing Them

[The Moose]

For some reason, in the shower this morning I was thinking about octane ratings and mixing them.

If you take 20 litres of 95 octane unleaded, and 20 litres of 100 octane unleaded, mixed them together (however you like and whatever process you want) what do you end up with? 40 litres of 97.5 octane or something different all together?

And all I was thinking was 'Not another grey one..!'

something between 95 and 100 octane - probably close to the middle but likely not exactly.

You will end up with wasting your time and money. The cost of 100ron (well lets say 98-99 since thats the mainstream high octane) compared to the 95 ste will mean that even if you do end up with 96ish ron, its barely better than 95, and far more expensive If that all makes sense

F1 engineer used to mix regular fuel with paint thinner toluene to boost the octane rating and prevent the pre-denoation knocking in engine under the huge boost.
