Lubricity

We test lubricity of distillate fuels by, ISO 12156-1/ IP450/ ASTM D6079.

Hydro-desulphurisation processing, as part of the refining process to remove sulphur from fuel, can also remove minor Oxygenated & Nitrogen-based species which give the fuel its natural lubricity.

The ISO8217 recommendation is to test fuels for lubricity when ever the sulphur level is less than 500ppm.

Ultra-low sulphur distillates have greatly reduced lubricating values for fuel delivery systems exposing pumping systems to possible failure.
