I came across a euro HPFP makers specification, below is the recommendation:
Allowed fuels (lubricity less than or equal to (<=) 460 micrometer)
- Diesel fuels complying with EN 590:2004 or ASTM D 975-05 (provided that lubricity is comparible with diesel fuel according to EN 590:2004.
(EN 590:2004—Sulfur limits of 50 ppm (so called Euro 4) and 10 ppm (Euro 5) as regulated by Directive 2003/17/EC. FAME content of 5%. )
http://www.vecc-mep.org.cn/news/e_laws_fg/EN 590-2004.pdf
Another interesting note about fuel:
First filling diesel fuel with a lubricity (wsd 1.4 @ 60C) <= 400 micrometer (HFRR) according to ISO 12156-1 is strongly recommended.
Diesel fuel may contain up to 5% (V/V) of fatty acid methyl ester (FAME) complying with 14214 (basically biodiesel)
All system surfaces which are in direct contact with the fuel should not contain Cu, Zn & Pb
also in the spec there are some disclaimers of additives, mixtures, improper fuels, etc. are not the HPFP supplier responsibility, there are the full responsibility of the OEM customer - therefore HPFP does not recommend anything other that fuel specified as EN 590:2004 or equivalent.
maybe a fuel expert can clarify more on this.....
