Dear M T friends, I bought a used Grandland last week (1,2, 130 HP BJ 12/2022, 9800 km . Now my question: with the predecessor , Meriva B I had to add an LM direct injection cleaner to the petrol every year, but now a timing belt in the oil (no control chain) runs at Grandland. Do you have any residue of the cleaner into the oil and can damage the ZR? Or the dissolved residues? Unfortunately, find the report where the engines were described, where this Zus In the case of other engines, the additional engine damage can be caused. Do I have such an “other” engine? My, I have an F12-xxx engine. Or should I absolutely wait with the addition until after the warranty? In the Meriva this was prescribed, at the Grandland I read nothing of it.. Ok, completely different engines, PSA miracles.. but unfortunately there was no other engine in the Grandland with any other engine, or just electric, but it stands on petrol dampers^^ oh, and still a question, kills the oil hlammflussung the timing belt,? I read horror stories and would like to keep my engine still n bitl^^.. Or just a premium sprite (Ultimax etc?) and your fingers away from additives? Thank you for your opinions:
