Currently I use Mobil 1 FS 0W-40 with LM Molygen MP and MoS2 for the control chain. Would you like to use my oil supply (15L) to switch to something else, because the molygen is quite overpriced. Should there be something with solid lubricant again, because I have a control chain in Smart 451! Would the Ceramo Ester from MANNOL be recommended? You get much cheaper than the additives from LM. In addition, I would like to add some ester and in the summer the MANNOL Motor Doctor (VI-improver) My Smart 451 Turbo has a Sport-LK and has been chipped, is now about 130hp. The Mobil 1 FS 0W-40 is certainly one of the best 0W-40 oils anyway? If the Mobil 1 FS X2 5W-50 is cheap on Primeday, I would probably take that for the summer. But unfortunately, most dealers only have the X1. In winter I don’t like to drive 5W oil!
