My Toyota dealer has a nice service schedule posted up on their wall. For my 88 Suburban I bet that service schedule would have been great. 19 years later, I know we've made some progress and my Toyota brochure / maintenance schedule doesn't include the VAST majority of this service ($600 30,000 service, for example).

I imagine I should go with my vehicle service schedule-is there ANY reason not to do so?
