What irritates me at the moment is the fact that a much shorter oil exchange interval is required for the Renault Clio than for the Dacia Sandero: Renault Clio: 1 year or 15000 km Dacia Sandero: 2 years or 30000 km This looks like a money tailoring for me in the case of the Renault Clio, because the Dacia Sandero is equipped with the same engine as in the Renault Clio. In any case, you have to comply with the oil exchange intervals in order not to lose the factory guarantee, that Renault knows after all What do you think about it?
