Grenadier Owner
If they are using the BMW LL12 Spec oil then it seems in line with what BMW do with the B57 in the X5,6,7 etc.20,000km service interval. That’s seems a lot especially on the first service. I’ll be looking at 10,000miles /16k km max service interval for my Grenadier especially for first service or heavy off road use.
That said I’ll be doing my own at 5k after “wear-in”. I figure BMW/INEOS are concerned with the engine getting through warranty period whereas mine is getting the vehicle up to half a million kilometres over ten to fifteen years.
