Re: 93 octane in stock engine

I've read somewhere(don't know in which magazine) but by adding the octane, the point at which the fuel combusts is higher. So in theory 87 octane burns at a lower temp while 93 would burn at a much higher temp. So in cold weather your supposed to run the lowest octane.
