Mechanical FI and Unleaded...

I'd suspect the concern is that unleaded offers different lubricating
qualities than leaded gas does.  In the Spica mechanical FI system, the
injection pump uses variable-displacement pistons that are lubricated by the
fuel they are pumping.  So far, the change to unleaded hasn't seemed to
cause too many problems to this system, but the newer RFG has many users
worried.  The current folklore cure?  Using Marvel Mystery Oil mixed in the
gas to restore some lubricating qualities.
