Misleading Cluster Reading

[EKS PYB]

This is somewhat the same as blackbeauty but not quite.

I was driving to work this morning and I suddenly saw the yellow OIL icon on the cluster. But I remember that when I started the X5 this morninb before leaving the garage I saw 3 Green Bars still.

I was wondering 2 things:

1. How many miles can I drive the X5 without the engine blowing
Home to Work miles roundtrip almost 70 miles one day...so can this wait
til Saturday?

2. Why spend the money to top off the oil myself as some of you have
suggested to blackbeauty when we have the maintenance warranty
and some of us paid extra for that when some of ours have
expired...shouldn't we use it?

Please advice!
