Apparently, in CA, it doesn't pay to drive veggie oil vehicle. You'll get hit with taxes..
What kind of tax you might ask? How about 18Cents road tax for every gallon of oil you burn. How about a license to transport kitchen grease away from eateries. How about 1 mill. in liability ins. in case of a spill while transporting. Not least, a permission from state Air Resources Board to burn fat.
I'm not sure how long the link will last but...here's the story.

This tax thing lead me to think....if I drive a car that use more gas, I'm paying more than a hybrid vehicle to use the same road , I should be the one using the the car-pool lane instead......LOL
