Sounds to me like you have it in manual mode.
But it's been so long since I drove an Auto Crossfire....

With synthetic oil going for $10 a quart and $15 oil filters, $120 is not a bad deal.
Of course, MY oil changes are done just past my laundry room in my own garage for around $78.

If they are REALLY doing a PROPER automatic service, $300 probably isn't all that bad.
