93 Octane fuel (Super Unleaded out here) isn't a bad thing to run in 
the
Dak's.  120...is definitley the wrong idea.

So has someone actually run a complete timing curve check on the 
Dak's to
see whether or not the Knock Sensor is actually working??  On older 
Chrysler
(Computer Controlled) Vehicles (GM & Ford included here), the Knock 
Sensor
(located on the block) would advance the timing until it "pinged" and 
then
back it down until stopped throughout the 2000-5500 RPM range.  
Running
Higher octane fuel usually gave slightly better performance...to a 
point.

I'm not saying that we should pour some "Mechanic in a can" Octane 
Booster
in our tanks...but try it and see what happens.  Especially you 
DML'ers with
access to Dyno's.  Put the vehicle on the Dyno and check it with 87 
and then
93 (or 92) octane fuel...Don't forget to put the printouts on your 
websites.
(I don't have access to a Dyno so I can't do it.)
