This was posted within another post. I should posted it directly..sorry for the BW use.

I live in an area (Clearwater, Fl) where we have a "special" fuel that is mandated by law. We did away with emissions testing in favor of this special fuel which reduces emissions, but may cause carbon build up in HP engines (anyone know about this??). I think this is called oxygenated fuel. It's available in 93 octane.

I drive very short distances to and from work (2 miles each way) and only get extended time in the turbo sometimes on weekends...maybe every other weekend.

My question is how will my local fuel and my driving situation effect tuning?
