My X5 got 7,000 miles. yesterday the low engine oil warning light went on on my dashboard. I checked the oil level and it showed me minimum level on stick. I checked my drivway and there is no oil stain on it, so I assume there is no leak. Please explain it to me before my appointment with dealer if it is normal to happen to brand new car. What could cause it. Waiting for yours answer.

Thank You,
Slavo
