The reason so much residue was in the engine is because of the tuning since the engine is set to run on 87. I promise you a good tuner could get an xD to run on 93 without a residue left behind. My LT1 V8 was probably running closer to max then the 4 banger in my Scion since the engine was designed to run on nothing less than 91 octane and the timing was already fairly aggressive. Plus as far as I can remember even the older Asian cars had to run on an after market ecu.
