HIGH FREQUENCY RECIPROCATING RIG TEST

(ASTM D6079-97 LUBRICITY TEST)

The HIGH FREQUENCY RECIPROCATING RIG TEST (HFRR) is a microprocessor-controlled reciprocating friction and wear test system which provides a repeatable assessment of the performance of fuels and lubricants.

The test measures the lubricity, the ability of the fluid to affect friction between moving parts.

In June 2008, several diesel performance products and Forté Premium ULS Diesel Booster ® were tested at their prescribed treat ratios.  The following competitors, in no particular order, were tested – Gunk Diesel Max, DSG 4Plus Premium, DSG 4Plus Arctic, Motomaster Diesel Treatment, Prestone Diesel Treatment, Howes Diesel Conditioner and Kleen Flo Diesel Conditioner.

A ULSD baseline was also tested and the following results were produced (results were averaged over 2 runs).High Frequency Reciprocating Rig Test Graph

COEFFICIENT OF FRICTION

Reducing friction in the engine allows more of the fuel energy to be converted to useful mechanical output, thereby improving engine efficiency.  The lower the coefficient of friction the more fuel efficient the engine.

SUMMARY

The Forté Premium ULS Diesel Booster ® performed the best compared to the 7 competitors tested on the HFRR.
