Makes sense. This car was asking for an oil change when I bought it, so I wonder if it got an oil change and a DEF top-up when it was returned at the end of its lease and they forgot to reset the oil life monitor? Possible I guess.

I've had a jug of DEF sitting in my garage since I bought the car assuming it will run out. Now I'm curious to see how far it will go before needing a refill. Also curious if that 9.5L (2.5 US Gal) jug will even top up the tank?

OK, so a little Googling says BMW claims 10k miles on a fill, so it must have been topped-up right before I bought it. 15k kms is getting close to 10k miles.
