Congrats, slybry, the Alpine White is so nice on most BMWs.
Just change the oil/filter more often than BMW recommends/pays for. You get one free oil service every 12 months regardless of kms driven. Change the oil/filter initially at about 3-4000kms, then again at one year or about 12000kms. If you are paying (outside the BMW-paid services, don't have the oil calculator reset, let it run).
In olden times, ppl used to check their gas supply with a dip stick as well. Then fuel guages came along, and few relied on them. Over time, technology improved and the doubters ceased to doubt. As with the electronic dipstick. I don't worry about it any more.
