Man I don't know about blends- some guys swear by them, and then some swear at them.... Scientifically speaking, being that most fluids used in blending have different specific gravities, they will not stay blended. But then again a lot of guys also say that thier blends don't separate. Once I mixed three parts JP-5 (jet fuel) with one part WVO, and it sat for two days not separating. I for one will stick with WVO, I don't have the check book for gambling!
