Well, when it comes to mixing actual gasoline mixtures, it's pretty simple. If you have half a tank left, and it's "93", then mixing in another half tank of 100 would bring the octane rating up to roughly 96.5 or (93+100)/2. That's plenty high to see if it's real knock or not.

I had a similar issue this fall. I had filled up in Jersey and the guy put in 87 by accident, but I didn't realize it till later when I had gotten on it in a later drive. I had crazy knock all the time, but put in about 5 gallons of 100 and it instantly went away, or within about 2-3 miles of driving.

I logged before and after the fillup and it was instant how quickly the knock went away.

Thanks for the info. I'm getting a couple degrees of kr from 3600-4800 or so. Timing was at 24 with 2*kr so I pulled 2 from the area and tried again. Same result. Pulled 2 more and still the same. I'm now at 18 through that area and still seeing a degree or so. Tried richening up the area with no change either. I'm really starting to think its noise from the solid mm's
