Its difficult to drain that fuel tank as its behind the rear seat. Get it towed to a shop and have it pumped out.


Not advised to continue to drive the car as you will cause damage to the Catalitic converter. The tank will need to be drained and recommend replacing the fuel filter aswell.


That sucks man :-(

you will also need to decarbonize the combustion chambers with some sort of solvent , like fuel injector cleaner or simmilar


Just fill the car with high test and drive the car its all fuel just different grade it won't hurt anything
