It seems to me that $22.99 per gal of castor is less then $44 per gal of Klotz synthitics but I was never very good at math.
I stated my qustion wrong in a way. The amout & $$ of fuel each product would treat one gallon of fuel is the question. I read you need a lot more castor per gal (20%) but synthetic you would use far less per gallon of fuel because of the much higer ratio you use(40-1 50-1 100-1) depending on brand of synthtic used. Gets kinda hard to figure this all out??? So there then is another question...what synthetic oils mix with alcohol and can you use a 80% alky/10%castor/2% synthetic mix??? Thanks capt,n
