Engine Misfire check engine light question
I accidentally used a mixture of gasoline and oil to fill up my gas tank. Obviously I assumed it was just regular gasoline, and didn't notice until I set the tank down and saw OIL +GAS in black marker. Anyways after that my check engine light was blinking which I know is an engine misfire. I'm 99.999% sure it's an Air to Fuel Ratio Imbalance since because the light stared blinking right after this happened, plus I was driving around earlier with no problems and had my car inspected a week ago. Anyways, I'm a complete idiot and know nothing about any of this stuff but i'm just wondering if I go to a gas station and fill my car up with normal gas as I always do will this fix the problem? Filling my tank with gasoline would to make since logically since it 's literally called air to fuel ratio imbalance but like I said I'm a complete idiot and know nothing about cars, i'm just going off of what I googled in the past hour. ANY ADVICE IS GREATLY APPRECIATED THANK YOU SO MUCH!
First question - how much of the gas + oil mixture was put into the fuel tank? If more than 2-3 gallons, then it is recommended to drain the fuel tank, and refill with fresh gasoline.
