Maybe Overthinking this but… I have a transfer tank in the back of my pick up that I used to haul Av gas from nearby airport to my hanger. I was thinking about cleaning it out and putting in unleaded auto fuel. Knowing that the leaded av gas will mess up my catalytic converter in the car. How do I know that I have the tank sufficiently clean before I start running it in my cars?
