2020 Toyota Corolla - Diesel Instead of Gas

Put 1 gallon of diesel in 2020 Corolla when I realized what happened. Then put 9 gallons of premium gas. Do I need to drive continuously about 300 miles before diesel is out of gas tank??

Another person putting diesel in a gas vehicle . No you don’t need to drive non-stop for 300 miles . Actually I myself would just do the normal routine with only 1 gallon of diesel . But if the check engine light comes on head straight to the dealer.
Are you in the US ? I ask because the diesel nozzle is not supposed to fit in your fill pipe.

Yet another reason I’m glad NJ doesn’t allow customers to pump their own gas.

One button labeled DIESEL the other button labeled 87, easy to mix up.
