The scam at the Toyota dealer's is to 'suggest' that every auto be serviced
every 3000 instead of 5000 miles, regardless of usage. And then they have
about $25 worth of 'extra dealer items', such as 'friction proofer' and
other additives that are routinely added, unless they're told up front not
to do it.

I'm very careful to tell them I want the 'book' service when I go in.

I give up. What the hell is friction proofer?
