I just got out the Service Center for (1,000 km service), since the dealership here have only sold a few stingers, I always double check with them to make sure they have not made a mistake. First mistake they did, was put 10w-30 oil when I clearly requested them to put 5w-30. So they went back and put the 5w-30 oil. And gave it back, once I checked the oil level, it was considerably above the "F". So I told them how much liters did you put - stating to them that the recommended amount in the manual is 6.9l - which they answered that they have put 7.2l. So I asked why have you done that? The said because they have changed the oil filter and with a couple hundred kilometres, it will go back to normal between "L" and "F". To be honest I'm not convinced, I'm no mechanic expert. So please guys tell me your thoughts about this? I'd love you knowledge feedback.
