My wife’s 2021 MB GLC 300 was purchased new and only serviced by the Mercedes dealership for its annual service. Part of the deal I made when purchasing included the first 3 services.
The owners manual calls for 229.51 spec oil which was used for the first two services. The last oil change was done using 229.5 spec 5w40. Should I be concerned that the spec was not followed? I should mention my wife only drives 8k per year but mostly city driving. We use only top tier 93 octane gasoline.
