The oil was changed before I bought my 524td. I don’t know what oil or weight was used. But would like to do an oil change. I use bmw 5w-30 diesel oil with archoil friction modifier additive in my 328d.
what oil and weight are you guys using/do you recommend for the M21? I use archoil additive in the 328d as it adds lubricity which helps prolong the life of one of its Achilles heals (the timing chain). Any benefit to using an additive in the M21?

What is everyone using for oil?
Re: What is everyone using for oil?
Delo 400 15w40, but I don't honestly think its that critical so long as its something of reasonable quality.
These do have a flat tappet cam and (IMO) a somewhat marginal top end lube system. Probably get more benefit out of making sure that oil sprayer is clean than any magic additives honestly but if you want to add something with some extra ZDDP the cam won't hate it. I don't know that its really needed though, diesel oils tend to have more stuff in them that is flat cam friendly than modern gas engine oils.
