Lye is the opposite of acid. It is alkaline.bluengreen said:Regen for Nox/DPF system requires post inject burning of the fuel and if it is B20 it will get into the crankcase and dilute the oil that lubes the engine (along with the acid (Lye) used in gen 1 bioD).
makes one hopeful that the price of ULSD will be parity with RUG nationwide in the near futurebluengreen said:However several producers are working on 2nd gen bio fuels like hydro treated vegetable oil (HVO) hydro treated vegetable fuels are very chemically similar to ULSD, go through the same refining process and will not pose a problem and would permit up to B40 blends. VW wants 2nd gen ASAP and is partnering to get it b/c it does not have farm impacts. Neste Oil in Finland started research in Europe for this, Conoco-Philips is working on it as are Shell BP and others. 2nd gen Bio D is also desirable because it is pipeline deliverable (unlike Ethanol) and can share the infrastructure already in place to distribute it.
Allan Schaeffer -Diesel Technology Forum www.dieselforum.org also spoke indicating Diesel supply should be on the upswing.

I think Krause meant acidity not acid. Either way it sheads light on why VW is skittish on Gen 1 BioDiesel and it suggests that a 2009 TDI may happily ingest BioD in Gen 2 at a far higher %, perhaps up to B40.fnj2 said:Lye is the opposite of acid. It is alkaline.
