Had the Swiss dealer change it. Picked up the car in a snowstorm (1 inch) never got out of first gear 15 minute drive took 2 hours (who say the Swiss can drive in snow?). Got bored driving home, checked the onboard system and it said that the oil level was too high. No warning had come up.
This morning back to the dealer who gave me a line about US Spec cars having a smaller sump. They removed some oil, scratched a rim (which they pointed out to me and will repair in the spring).
Next time, I will do it myself.
