My first post.................... . In response to desperation marketing, I've been in a shop where this has happened. Empty bays, techs sleeping on their work benches.......Here comes the manager with a "new idea". " Let's start selling any and every possible Flush available." This didn't work at all, especially because most cars coming in were still under warranty and had never heard of these flushes when they brought their last 5 cars in. This kind of marketing leads to unhappy customers and unhappy techs.
