ok, my dad just got 4oz of ''CASTOR OIL U.S.P.''. It says 100% castor oil. So let me get this straight. I poor the 4oz of castor oil into 1 gallon of coolpower 10% and then shake? Once you say ok I'll do it. My dad wants to make sure that I don't ruin a gallon of fuel.
The 4 Oz of castor will make the Coolpower a much better fuel.
