Fuel injector cleaner can be some nasty stuff. Just like ethanol, it
tends to lead to corrosion. I would be less worried with your Quest than
with most American cars, though, as the materials used in the fuel
system are better quality. All manufacturers say to not use gasoline (or
oil) additives. In general, they are just not necessary, and potentially
harmful.
