As per my post a few days ago.I was all happy with the improved mileage my 6.0L 4x4 crew cab GMC had after a heavy hauling trip. Turns out the 1st tank of 87 octane dropped the mileage back down to "normal". While towing in hot weather I had been running her on 91 octane. So that last 91 tank fill at the pumps and a 91 tank fill from my Jerry Cans at home. Had me thinking the soot was cleaned out of her and had everything beded in and seated. Next fills will have to be 89 & 91 octane and keep some notes on what's going on. There must be enough compression pressure in that engine. She's sensing knock and retarding the timing when running on 87 octane? It might be one of those vehicles that's cheaper per mile to run on premium rather than tractor octane.
