[AT] Synthetic Oil

[charlie hill]

There used to be a device that you could add on to your turbo'd vehicle
that pumped oil over the turbo bearings for a few minutes after shut down.
I can't remember the name of it.  I don't know if it worked or if it's still 
made.

I guy I know that has an excavating company always lets his diesels idle
for 15-20 minutes before shutting them down after a day of running. I'm
wondering if it's meant to cool and keep lubrication going to the turbo.
