Increase in carbon deposits in the combustion chamber increases compression ratio. If you do get ping because of this, then you should use higher octane.
These engines run at very high rpms, and as long as you don't lug the engine under load you should be ok on 87 octane.
Personally I have been using 91 cause just in case I get a batch of bad gas!
