If you look in your owners manual, the 30k mile service is basically a glorified oil change. There are a bunch of "inspections," but no fluids are recommended to be changed or anything like that. Lube the hinges, check the air filter, etc. My dealer tried to sell me all this crap for my 15k mile service, which should be even less of a service. They wanted to flush the coolant, transmission fluid, change the air filter, and clean my throttle body and fuel injectors. NO THANKS!
