Oil change after 5000 km ?
Hi,
My 2017 M2 had a BMW oil service at 24000 km in july 2020 Now it has 29000 km Dealer tells me I have to change oil Do I really need to change the oil and filter even if I drove only 5000 km ??? I thought that the oils now are much less hygroscopic than before and I could wait 2 years... |

Now despite the fact that oil doesn't absorb water (moisture can still be present in oil just not absorbed into it, but with the presence of water the oil will become milky and that is really bad as well) it oxidizes over time so oil shouldn't be used past the 1 year mark. Also if you have alot of water in your oil you'll have to change it as well. Note 5,000km is around the beginning stages of when you should normally change your oil if you want your car to last, bmw's standard service interval is much too long. Remember oil is cheap engines are not, so change your oil frequently it is the cheapest insurance you can get for your car.

1) there is no oil quality sensor, only an oil life algorithm. This works on heat put in the oil, length of journeys and time since last oil change. The manual says to do an oil change every XKm or 2 years, whichever comes first. It is now just going by the age of the oil. 2) Unless all your drives are under 30min long you do not need to worry about water in the oil. The oil gets to 120c in normal conditions, enough to evaporate all of the water in the oil. If you get Mayo you have a bigger issue or have been only driving short journeys. A long drive will sort this. 3) Oil health and miles are related but not the be all connection. 5000km on track will have a different oil wear to 5000km doing 100kmh on the highway. The reason Americans change their oil more often is (in my opinion) partly cultural (quick lube propaganda) and because of their shit fuel with more sulfur that will acidity the oil sooner than say EU fuel. I would change the oil, it's cheap to do and ensures it's good. This is a high performance turbo car, it needs good oil to live a long life. If you don't track I would follow what the car says. If you do track then change it more often. The only way to know for certain you have the "right" interval is to have the oil tested. Not big in the EU (for cars, boats it's more common) but there are some companies popping up to do it.

5,000km is just just over 3,100 miles.
Noting that some parts of BMW Europe mandate 2 year intervals for oil service, It may be that you can safely leave it another 12 months based on the distance travelled. Obvs. if those were 5,000km of trackdays (or you've been 'visiting friends' in southern Germany on a regular basis), change the oil and filter as it won't hurt, and is cheap compared to the cost of pretty much any repairs.
