I cannot remember the last time I drove my Mercedes to a gas station. I live in California and since the state is going broke I would not put it past them to come up with something like this. I have a waste oil hauler license for personal use issued by the Dept. of Agriculture that allows me to carry oil in the car. If the oil is in the tank all bets are off and you do not need a license. But I bet they will find a way of making up on lost tax revenue. Thanks for the heads up.
