Regarding gasohol and fuel injectors.

One of the local (Portland, OR) technical officers of the local
BMWACA club attended a BMW service talk given by a Bosch rep.
Bosch is responsible for most fuel injector systems available
today.  

The rep said Bosch fuel injectors of all kinds are ruined by gasohol.
Fuel flow through the orifice of an injector is extremely carefully
calibrated in the manufacturing process.  Gasohol and water have been
demonstrated time and again to slightly erode the metal parts in the
orifice, causing uncalibrated fuel flow, and in Bosch's opinion, ruining
the injector.  Water is another killer, not only for diesels, but for
gasoline injection systems as well.  He recommended one of the old
in-line settling bowl type water separators.  The stock filters
on Bosch systems can be overwhelmed by water, apparently.
He also said that if you go into a gas station for a fillup and
see a tanker truck unloading gas, do NOT buy any gas there.  The act of
filling the underground tanks stirs up the inevitable glop, water, and
sediment for at least 24 hours.  This will very happily deposit itself
in your fuel system, most likely where it will do no good.

Food for thought. . .
