- Increases lubricity of diesel fuel at low treat rates
- Low viscosity allows handling down to -10°C (14°F)
- Compatible with all commonly used diesel additives
HiTEC® 4171 Lubricity Improver is a highly effective solution for lubricity improvement in diesel fuels. Sulfur levels in diesel fuels have been reduced worldwide to improve vehicle emissions and enable advanced exhaust treatment systems. In reducing sulfur levels the inherent lubricity characteristics of the fuel are also significantly diminished.
The importance of the lubricating properties of the fuel is becoming more important as advanced vehicle designs use increasingly severe conditions to meet efficiency and emission targets. Vehicle manufacturers typically consider the lubricating properties of a diesel fuel with less than 350 ppm sulfur to be unacceptable. The importance of diesel lubricity characteristics are recognized by minimum performance criteria in fuel specifications. For example:
Treat rates will vary depending on base fuels. Afton Chemical recommends using HFRR test method CEC F-06-A-96 or similar to determine specific treat rates for your application. Typical treat rates are suggested at 50 to 100 ppmv depending on the fuel response and target performance.
