Hello Nurse Ben
The above thread was about a mistake that occurred with a particular Chrysler bulletin . It was also referring to pump bio-Diesel fuels,,,, not home made
You are right to be confused as such.
However this is specific to the Sprinter
Quote on the original OM 612 engine..Diesel Bio-fuels literally had the potential to destroy the engine, as to the fatty acids breaking down the rubber components on the engines seals, this also had issues with injectors EGR valves and turbo failure a small plastic seal that corroded in part from unburnt oils but from excessive High sulfur content which was highly corrosive, which had the potential to detonate the engine, $$$$$ as to being not compatible to certain bio-Fuels this lead to major problems with John Deere engines, Caterpillar, and Detroit engines or Cummings cant remember which
in part it was because of the process of different types of fuel additives, veggie oils for example gelled up at lower temps causing issues etc and the list went on and on , the injection system was not designed for bio-Fuel past a recommended level, hence warranty void
if you exceed it, and had issues with the manufacture, they had right of recourse to refuse warranty, Chrysler engines USA using the 5 in-line in the local makes also would not cover warranty on this,let alone oil sludge, etc.
It is not a matter of silliness as to using over 5% bio-fuel its how the process is formulated and to which feed stock !or modified- waste-oils _ being used,
this is a major concern with problematic on going issues Now 2007 with an engine manufacture.. on a Diesel engine, a modern one that is.
The equations of investigation did come to a conclusive out come in Europe, Australia, and the N/American sector , that bio-type Diesel fuels had two down sides under certain applications of processing, the lubricity was lowered and corrosion from fatty acids, did damage vital engine parts to prevent it from operating at the designated fuel pressures, thus lowering the capacity of a PDF to deal with the excess high sulfur emissions.out side of the Bin emission codes for the year designated.
I'm not against Bio Fuels, but question the process
and appreciate the manufactures concern ,as too a non uniform process, with different results from oils, and feed stocks. The injectors are set for Diesel E5 to E 10 this is not a problem , but after this? as to B100 then the engine requires to be modified to handle it, and this is because of emissions which come into play.
Use a home made bio-fuel by all means, but do not expect the manufacture to repair 'THE ENGINE UNDER WARRANTY'
if it fails.
Bio-Fuels can be placed on another thread for interaction with members etc, they interest me.
Making the point this is for the Dodge Sprinter!.. it does not refer to other engines years or makes, be it a MB product, or from another manufacture.
