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. . . Don Chitwood Teklabs, Tektronix, Inc.
