Easiest thing to do is drain the front sump. Get half-litre out. Then start the car and let it run for 30 seconds. Then drain it again later in the eve once it cools and repeat. You can get at the front sump without lifting the car which is nice.
Driving with almost 2 extra litres is not a good thing I would have to imagine.
You really dumped 2 entire litre bottles into the thing and called that "topping off"??
