At least part of it is due to the oxygenation of the gas. How much of the gain is due to oxygenation vs. high octane and/or ECU adjustment is impossible to say from this test alone. But I think it's enough to at least cast doubt on many of the positions that have been taken on this thread thus far (like the position that race fuel won't produce any gains on this car unless it's highly modified or tuned to use race fuel, for example).
