Cold weather and detonation?
Not trying to start a debate over which octane is best...
Can anyone tell me if cold weather is more or less likely to affect engine knock? I use 87 octane (as prescribed by the owners manual) in my '05 600RR and noticed a lot of knocking on the way to work this morning. I've been using the 87 octane for months and have never noticed this before (even in the hottest days of summer).
