The original anti-detonation fluid was straight water, but that would freeze in the cold climate states, so methanol was added to suppress the freezing point. The Olds engineers found the mixture with methanol actually gave the engine about a 5 horse power boost, bring the rated horse power up to the magical 215, 1 HP per Cubic Inch!

The water soluble lubricant was added to the mixture to “coat” the rubber components in the Turbo Rocket Fluid delivery system to minimize the leaching of plasticizers from the rubber components, that would make them brittle and non-flexible. Methanol is hard on rubber components!
