Update on the Escalade...its a daily driver. I have put almost 5000 miles on it, and am loving it! It goes where I want it to go, and I am comfortable doing it. It just eats up the miles.
Shortly after I bought my Escalade, my wife brought me a souvenir back from New Orleans. I now have a pirate voodoo doll hanging from the rear view mirror. He is my Copirate on all my drives.
I am draining the catch can every 1000 miles, getting around 1/2oz of oil/water/milkshake.
I have been trying different brands of fuel and different gas stations, all while monitoring knock retard. I will run the fuel tank as low as I dare go, then refuel with 24-25 gallons of the selected fuel. I then drive until the fuel tank is down to 3/4. This ensures all the last batch of gas is gone. I then monitor knock retard, engine load, engine RPM's, and vehicle speed via the Tech 2 on my drive to work. This drive is consistent, so the data points are the same for each test.
So far, the results have been consistent: I see around 5 degrees knock retard at part throttle, around 1500RPM and around 60MPH. It seems to happen most when the grade increases slightly. This has been very repeatable.
I will continue this testing until I find a 93 octane fuel in my area that doesn't cause knock retard, or I run out of gas stations.
