Hi mate. Got a merc van its 122 CDI V6 engine, just done 58000km! I wanna use Cera Tec LIQUI MOLY oil additive, to keep the engine clean and reduce the engine temperature as I have a lot of short drives around the city. I’m really in doubt and looking for some professional advice. Is it okay for this sort of engines? Have you had any experience using additive Liqui Moly products? Much appreciated
Hi, Sorry no experience of Liqui Moly. Best to speak to a Mercedes workshop or Mercedes specialist on this. We would only use manufacturor recommended lubricants. Thanks Simon
