I know diesels can burn oil which is normal (have never removed my dipstick, the checking procedure seems to be a little different then pulling and reading)

Does diesel oil get contaminated that earlier change intervals will be better? I love this car and want to keep it forever hence best performance for longevity.

Should I change the filter or no? Also what kind of oil? I know the dealer will use their oil so i assume i should use that same to keep the blend the same. Although I'd love to throw some nice amsoil in it.

any advice or open to discuss? thanks!
Any oil with BMW code LL04 will suffice.
In the US that basically means:
-Castrol SLX OE Prof 5w-30 available at BMW dealerships and maybe Audi/VW.
-Mobil 1 ESP 5w-30 (Pepboys, Autozone, etc)
-Valvoline MST 5w-30/5w-40 (NAPA, and probably others).
- Motul & Total (Has a few LL-04 but they're usually mail order only)

M1 ESP 5w-30 is the cheapest by far (~$7.50 quart) in my neck of the woods.

There are a few dozen or more oils but they're only available in Europe/Asia.

PS. Always change the filter.
