extended service coolant / evans cooling npg

[guss [ jim, elizabeth & pablo guss ]]

hi --

i have just come across product i thought you might like to hear about:  npg
or non-aqueous propylene glycol from evans cooling.  heard about it from
ldriders who heard about it from goldwing group.  info. avail. @
www.evanscooling.com .  ymmv.  no connection with company other than
intrigued by product.  figured you guys with more experience with this stuff
might have something good to say concerning this stuff.  i cannot certify
any claims, (ie., i don't know if this is total hogwash,) but it looks good.
it might be the end of a lot of cooling hassles -- like where do you put
that temp gauge? -- because, they say basically you can't boil over the npg.
bike race track legal and some racers use it.  also some auto teams
apparently.  i dunno; looks neat.  i pass it on for you to check out.  happy
motoring.  keep cool.  --  j  .

        "Reduction of Hot Spots
                (Critical Metal Temperatures
        Higher Gasoline Efficiency.
         Reduces Emissions.
         Higher Compression, Power.
         Knock Reduction.
         Improved Octane Tolerance
        Elimination of Overheat and After Boil.
        Elimination of Cylinder Wall and Pump Cavitation.
        Elimination of Corrosion on Cooling System Parts.
        Significant Reduction of Coolant Leaks; NPG operates at a low (i.e.; 4.0 -
7.0 PSIG ) or                   atmospheric pressure.
        Not a Hazardous or Dangerous Waste.  ** :-)
        Long Life, Stable Coolant.
                Increased from 40,000 (with EGW) to more than 400,000 miles. The system
has
                been tested to 400,000 miles in a Class 8 Detroit Diesel engine 
running at
                North American Van Lines. After 400,000 miles additives have decreased 
by
                only 11%, still within initial manufacturing tolerances for the 
coolant.
        Non-pressurized: (or lowpressure, i.e. 4.0 psig) decreased leaks, lower
pressure parts,                         decrease of thermal flexing or cycling

extended)
        Allows for a totally closed system (Hermetically Sealed)
        Elimination of premature spark plug failure and head cracking by better
cooling of head.
        Reduction or elimination of pre-ignition and detonation."
