Toluene write up

[Ron Wainwright]

  Eric, and others

  I just reciently within the past 2 months did a
timing belt on my 5ksq,
 so a while back I bought a Blau sport cam shaft from
the marketplace and finally got the chance to put it
in my car.
 Since my car is a NON TURBO thats about all I can do
besides an exhaust and a chip from Ned at IA.

 I did mostley highway driving probley 70% while the
other 30% was city/country driving.
 I used Mobil 93 octane then added the Toluene which
has a (R&M) rating of 114 which gave me a 94.4 rating
with 17 gal of gas.

  Other answers to you'r questions can be seen at
www.elektro.com/~audi/audi/toluene.html
 Hope this helps
Thanks
Ron
