Technical case study format

The HFRR (High Frequency Reciprocating Rig) was used to measure diesel lubricity by rubbing a steel ball on a plate in a bath of fuel. The ball develops a flat spot over the course of the test which is called the wear scar, the diameter of which is the measure of diesel lubricity. All diesel sold in South Africa must pass this test with a maximum wear scar of 460 microns, which does ensure adequate lubricity for all diesel fuel systems. This is the same specification as applied in Europe and many other parts of the world. The results in Figure 1 represent the fuels tested as per Table 1.

  • Recommend the best course of action.
    State your choice for the best course of action and provide a detailed explanation of why you made this selection. You may also want to provide an explanation of why other alternatives were not selected. Your final recommendation should flow logically from the rest of your case analysis and should clearly specify what assumptions were used to shape your conclusion. There is often no single "right" answer, and each option is likely to have risks as well as rewards.
