Re: Fuel additive and P20ee code...
I just bought an EcoDiesel JGC and have every intent of running Stanadyne Performance additive as well as their Lubricity addivtive, and maybe even a little Amsoil Cetane boost as well, just as I have my VW TDI (2.0L and 3.0L) and BMW 3.0L 3-series diesel.
What have others been adding that threw codes? Where have you noticed the codes, on the message menu or a OBD-II scanner?
Stanadyne even has a VW part number and does nothing but good things to diesel fuel (they primarily make diesel fuel injectors) and on a vehicle like my previous BMW 335d whose PCM could adapt to the higher cetane levels with the cetane boost, it purred like a kitten and ran like a beast with a little extra quality additional cetane. Fortunately, the area where I live in Texas is covered by the Texas Low-Emission Diesel Act, which mandates a minimum 48 cetane, but I would cringe to run that B20 junk in Minnesota or Illinois.
