Southwest Research Institute’s IDID Test
Overview of the Test:
The Internal Diesel Injector Deposit (IDID) test conducted by Southwest Research Institute evaluates the impact of DF5 on the formation of deposits within diesel injectors. Injector cleanliness is critical for engine performance, particularly in modern high- precision fuel systems.


Testing & findings
Test Procedure and Parameters:
The test focused on assessing the propensity of DF5 to form deposits in critical areas of diesel injectors. Southwest Research Institute utilized advanced testing methodologies to simulate real-world operating conditions and closely examine the injectors after exposure to DF5-treated fuel.
Key Findings
Effective Deposit Control: The results indicated that the use of DF5 in diesel fuel does not contribute to harmful deposit formation within injectors. In fact, it showed a tendency to control deposit build- up, particularly in hightemperature areas of the injector.
- ‘No Harm’ Effect: The test results confirmed that DF5 has a “no harm” impact on injector cleanliness, maintaining the efficiency and longevity of the fuel injection system.

Implications for Fleet Vehicles:
- Maintaining injector cleanliness is vital for the performance and efficiency of diesel applications. The IDID test results from SwRI affirm that DF5 is free from harmful ingredients and aids in keeping these critical components clean, ensuring optimal engine performance.
- For fleet operators, this translates to consistent engine operation, reduced risk of injector-related failures, and potential savings in maintenance and repair costs.
Conclusion:
The IDID test by Southwest Research Institute solidifies the position of DF5 as a fuel treatment that enhances engine performance by maintaining injector cleanliness.
