This is not giving me a warm and fuzzy about ULSD in the US. The following paragraph is the one getting TDI Club members' panties in a bunch.
Basically, it looks like the OEMs are saying all bets are off with ULSD here. (Thankful I've been adding 2 quarts of B100 per fill since tank 1.)
This is not giving me a warm and fuzzy about ULSD in the US. The following paragraph is the one getting TDI Club members' panties in a bunch.
Lubricity: It is essential that the lubricity of the fuel as measured by the HFRR test specified in ISO
12156-1 meets the requirement of a wear scar diameter not greater than 460 microns. In addition, it is recommended by the Diesel FIE manufacturers, that “first fill” of the fuel tank should be with fuel with good lubricity characteristics (HFRR < 400 μm) in order to guarantee good “run-in” of the injection system components. The US diesel specification (ASTM D 975-09) includes a lubricity value of 520 μm maximum (according to ASTM D 6079). It is expected that the useful operating lifetime of any mechanical component will be adversely affected by fuel with a lubricity exceeding 460 microns.
