Vehicle manufactures see diesel fuel lubricity as a critical parameter because certain parts of the fuel injection equipment (FIE) depend entirely on the fuel for lubrication. For example, a fuel with poor lubricity can cause catastrophic levels of wear to critical pump components resulting in fuel pump failure.
To protect fuel injection system hardware, fuel specifications include lubricity requirements, which limit the wear scar diameter; the parameter measured using the HFRR (D-6079) test.
This lubricity additive is non-hazardous and monoacid based.
Current fuel specifications include the lubricity HFRR test. In the USA the ASTM D-975 limit is 520 mm.
In Europe the EN-590 limit is 460 mm. The World Wide Fuel Charter recommends a max wear scar of 400 mm.
The HFRR test is now used in several industry diesel fuel quality standards: ASTM D-6079 / ISO-12156-1 / BS / EN-590 / IP-450-2000 / 50-98 / CEC F-0-A-96 / ASTM D-7688
