In another post in an octane thread, someone mentioned they needed to raise the octane level during the hotter months there. (desert type heat temps)
It started me wondering... can this be true? If anything, I would think cold weather would require a higher octane level as the oxygen content is higher per cubic foot of air when it's cold than hot, and having more oxygen per cubic foot would lean out the mixture leading to denotation.
But, does (ambient) heat play a role in denotation as well?
school me with your experiences or your physics class.
