Have the following problem: … had a service done with oil change and from 5W30 GM on mobile 1 0W40 “oiled”, air filter was also exchanged. Apart from that the service almost a 1/2 to 3/4 liters put in too much, which we then pumped again after about 30 km of city trip, the current oil level at maximum. After the oil change (which now does not necessarily have to be cause…) the following symptoms: 1) rougher, louder motor run than with the 5W30 2) quiet hissing in the mo 4) light oil moisture at the rear of the transmission bell (i.e. from the rope fork to the spray wall downwards, but now no crowds, it doesn’t drip) 5) at this point I’m not sure if that’s not the case – if it’s cold, stand gas at almost 1000 rpm, after 3 min drive 800U/min (with corresponding drop to 600 rpm to paa r seconds, for example, at the traffic lights). So far he didn’t have that, that when he was cold, he had increased revolutions in the stationary gas (he always had 800 rpm before). … what could there have been – it doesn’t clack anything, and my wife wouldn’t have noticed it at all – but I did. Can it be that they’ve put a software update on me? Was there one for the SC 2006 9.3 II gasoline? Can’t it all really rub it all together for me. Could it be that he’s pulling the wrong air somewhere? mmering? injectors? Ask for tips Thank you
