Not being critical here but if anything I own is dropping massive amounts of oil the key stays in my pocket not the ignition switch until I figure out what is going on and check the oil level once I do.
That being said, when I bought my 2015 Trail a couple of weeks ago they touted the ToyotaCare 2 year service. I can assure you my new 4Runner will not be getting ToyotaCare anywhere but my garage. I'll spring for the oil and filter it's not that big of deal and I know it's done right when I do it.
When you consider the hassle of driving to the dealer, waiting, the possibility of door dings or other damage, who is going to do the oil change (probably not one of the lead techs for sure)... just not worth it to me for something I can do in 1/2 hour correctly myself.
