Maintenance schedule for leased car

Do I have to keep up with maintenance schedule for a leased car?

I went to the dealer and do a $190 type 2 service and they wanted me to change an extra air filter (for riders air intake), this would last me one year for $85. With others extra parts, when I finally got out the door, the bill is $385.

I wonder what would happen if I skip some services or just do regular oil change/filter change. Do I have to go to dealer for lease car? Would it be a problem when I return my car after 4 years?

Thanks

The short answer is no.
