Dealer gives 4-yr deluxe service for free. Just want to know how much it is worth.

My another family sedan costs $30 for each engineer oil change. So G37 oil change is worth $50? 4-yr, it's 8 service for schedule 2, so totally $400?

 

I just got my oil changed, and it cost a total of $44.82 with tax. I do all of my own air filters (engine, cabin), and only have basic oil changes done at the dealership.

The service is worth whatever you paid for it. Believe me, they aren't just giving this away...they're using it as a sales tool, and including it in the cost of the vehicle. Dealer service departments are what keep them open, so they don't give service away, period.
