So should I run a LL-04 oil for now (I move back to the states in six months), then change the oil again to meet the LL-01 standard while I am in the states or can I keep the LL-04? I have heard these standards are due to high sulfur content in the gasoline in the states, and a low sulfur gasoline in Europe. If my car in fact had LL-01 in the car from the get go, did I harm the car by keeping that oil in there for the break in period using European gasoline? I honestly didn't have the choice to change it, as the Germans are sticklers on wasting oil products. They didn't even want to change my oil at 1200 miles, but they finally agreed to make the appointment. Sorry lots of questions, but I love this car and want to take good care of it. Help anyone?

No harm to your car. LL01 have higher TBN to combat additional acids created by higher sulfur laden US fuel and you don't have a diesel. US gas can have more sulphur when compared to ULSD
