I have a problem. I accidentally put diesel in my car. I used a gas can for diesel and marked it diesel with marker. I put about a gallon in. It was smoking and surging. I added about 6 gallons to dilute it. That helped a little but it still is not right. What do I do? I am thinking run it almost empty and fill with high octane premium fuel to counteract the very low octane of diesel. What do I do?
