Premix your 8, get better gas milage

I'm curious why premixing gains MPG though... I would assume the PCM would manage most of that, is there something that would detect the additional level of oil in the fuel? What would create this change?

I'm curious myself as to why it might increase MPG. Don't have the answer there, I just know that I have increased my overal milage after premixing and my driving style or conditions have not changed between the non premixed tanks of gas vs the couple of premixed tanks I've run.

It would be interesting to see peoples various results between running it and not running it.
