When using WVO, the adage is to modify the car or modify the fuel. If you decide on blending your WVO:

10 gallons WVO
1 gallon kerosene
1/2 gallon regular unleaded
8 ounces Power Service Diesel Kleen cetane boost

And 2 ounces of the secret ingredient - a mixture of:

Xylol (Lowes paint dept.)
Sta-bil fuel stabilizer (Walmart)

This stops the white smoke at startup and breaks up water.

Some people (like me) prefer to omit the gasoline and add a little more kerosene or some diesel. RUG seems a bit spicy for my engine.
