Filter it a couple of times and then chuck it in the Diesel car
Careful though. Doesn't vegetable oil have to be chemically treated to
change the viscosity or something to turn it into biodiesel?

vegetable oil does need to be processed to make biodiesel and an engine
modified to run on it. Cars can be modified however to run on straight
vegetable oil, either vrigin or waste.

Small amounts mixed in to diesel will go unnoticed. (Like a cup full per
tank.) To run on pure cooking oil you have to remove the glycerine.

Just for reference the US Army are testing disposing of waste engine oil
by mixing it with diesel fuel. It works!
