640i oil top-up
Approximately at which point does the electronic oil level system indicate that a top-up is needed and does it states the quantity required?
With 3k miles from new, the screen on my 640i is indicating just over half full, but it's still green and there are no other indications.
My instinct tells me to add oil now, but without knowing how much is required, I could easily overfill.
My previous two BMWs were extremely oil-frugal 6cyl diesels and I have no experience of modern petrol engine oil consumption.
Any advice much appreciated - many thanks.
