Oil capacity of a DT466 will fully depend on what oil pan it has. It can be 15 liters more in one bus from another.
Like has been said, 15/40. Brand don't matter.
Diesel oil contains detergents to break down the carbon buildup. Carbon is what makes your oil turn black.
Oil capacity has no reflection on changing interval

. Time and mileage, which ever one comes first is what dictates oil change interval's.
At the shop where we keep 400 buses running, we change oil on regular rout buses every 20,000 km. On buses that fill in as spares, we change the oil every 6 month's, regardless of the mileage on the oil. This is due to condensation leading to water buildup in the oil.
So, get a big pail, crawl under your bus, drain the oil, pull the big a$$ filter, reference how much oil drained into the pail, go to the store buy the same amount of oil plus 2 liters, use the old filter to get the right new filter, go home, fill the new filter and spin it on the engine, replace the drain plug, fill the engine with oil.
Careful not to overfill the engine oil. This will lead to leaking seals.
When you think it's close to full, check the dipstick. When it reads full, start the engine for a few min to get the oil flowing, shut it down, check again.
Always warm the engine up to operating temp before draining the old oil.
Make sure to fill the new filter before installing it on the engine.
Failure to do so will cause the engine to run for a few seconds with no oil pressure, damaging the engine.
