I beleive Sir Harry Ricard used 30-50% of fuel volume as a norm.
(this figure may have been primarily for turbo/supercharged appl).
Lots of folks have used a windshield washer tank/motor as a
dispenser (use a check valve so low manifold vacuum doesn't
draw it out).  Also anything more than just enough to get rid of the
detonation is a waste of fluid.  No real gains past that.  Might
be more info in archives, about this.  ie injector types methods.
