Adding new Soy Cooking Oil

[R C Cola]

Have seen the test of additives and would like to know if anyone has solid info on adding new Soy cooking oil to fuel and in what ratio. I have been using 20oz per 40 gallons and the truck likes it fine (roughly same ratio as Lucas reccomends) at 600k pump rebuild no wear on parts that could be felt with fingernail. This is the test result referred to: ---) 2% REG SoyPower biodiesel - HFRR 221, 415 micron improvement. 50:1 ratio of baseline fuel to 100% biodiesel 66. 56 oz. of 100% biodiesel per 26 gallons of diesel fuel Since Bio Diesel is thinner than cooking oil so I am wondering how much of the thicker cooking oil would be needed to get lubricity up.
