octane rating of some small alcohols

[Chris Conlon]

Here's a question I've been meaning to ask for a little bit.
Does anyone know or have pointers to the octane ratings of:

glycerol (aka glycerine)
ethylene glycol
propylene glycol
isopropyl alcohol

I'm wondering if any of these might make good additions to the water
being used in a water injection system.

   TIA,
   Chris C.
