More important than giving you a direct answer to your question, is that you understand why adding too much oil is bad for your car.

The oil quantity (level) was determined, by Vovlo engineers, to fall within a range of too little, or to much.

To little, and the consequences are obvious.

Too much and the crankshaft starts hitting the surface of the oil in the sump, pounding air into the oil (foaming) and making the oil unusable. Additionally, too high an oil level will cause oil to lay against you main crankshaft seals, encouraging a leak. Remember, those seals were not designed to have a body of oil laying against them, only the occassional splash, or squit, or ooze.

That extra 1/2 liter will not hurt your car. But if you do put too much oil in, just loosen the drain plug and let it drip out 'till the level is correct.
