 When I have somebody come in and they say I've put two or more converters on my car within 10,000 miles, I've got to ask them, does your car use any oil at all? And they say, oh, you know, about a quart every couple weeks. Not that bad at all. It doesn't smoke or anything. It's like that will ruin a converter right away. Okay, yeah. See, my van does use a little oil, yes.
