OK,
I paid $780 for all maintenance thru 55k miles...
They gave me the premium service, not the basic.
A premium oil change costs $84 each at 5-10-20-25-35-40-50 and 55k miles.
These include engine treatment (I assume cleaning).

15k lists at $149 and includes fuel injector cleaning and battery service.

30K lists at $369 and includes fuel injector cleaning, radiator flush and fill,
battery service with leak test, cumbustion chamber de-carb service (?), inspect, clean, and adjust brakes.

45k lists at $275 and includes fuel injector cleaning, transmission fluid drain and flush/fill with conditioner, battery service.

All of the above have the usual tire rotation, oil change , fluid top off, system inspection. Also includes roadside assistance for 4 months/5000miles.
Car wash any time I want one and with any service.

I think I got a great deal....
