2007 Honda Accord

I was running low on gas and it was midnight, so I went to a gas station that I never been to before and used my debit card to pay at the pump and I picked up the regular nozzle and pushed the button but nothing happened so I put the nozzle back and picked up the diesel nozzle and pushed the button and the pump started working so I put diesel in it by accident and it was about 2 gallons worth and I drove over 20 miles, so I just burn out the gas and then put regular gas?

If the ratio of diesel is too much, the engine should be running erratically and there would be a lot of smoke from exhaust.

You can do as you mentioned but I would fill up the tank with gas to dilute the diesel if it is driveable.
