[200q20v] Smooth Running

when It gets hot, try a gallon of Toluene with a half tank

see:   http://elektro.com/~charlie/photos/cars/audi/toluene.html

It makes a pretty big difference up here in Colorado with pump gas being 91 
octane plus 10% ethanol.  When I run 1 gallon of toluene with 8-10 gallons 
of 91, the car is much smoother, much stronger, turbo spools up quicker, 
feels much faster off the line.
Only draw back was a little more cranking time to start (maybe my 
imagination) and made for $$ tank of gas.
