The HFRR (ASTM D6079, ISO 12156-1) is a microprocessor-controled reciprocating friction and wear test system which provides a repeatable assessment of the perfomance of fuels and lubricants.
The test measures the lubricity, or the ability of the fluid to affect friction between mofing 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 - Gunk Diesel Max, DSG 4Plus Premium, DSG 4Plus Arctic, Motomaster Diesel Treatment, Prestone Dieslel 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).
Reducing friction in the engine allows more of the fuel energy to be converted to usedul mechanical ouput, thereby improving engine efficiency. The lower the coefficient of friction the more fuel efficient the engine. Forté Premium All Season ULS Diesel Booster® performed the best against the 7 other competitors.
An International 9900 Truck with a 2001 Detroit 60 series motor (6 cylinders) with 1.2 million kms failed a SAE J1677 Snap Acceleration Emissions Inspection.
One litre of Forté Premium ULS Diesel Booster® was administered through the fuel tank and the engine ran for 1.5 hours. The truck was tested on the following day and received a pass.
The Opacity % was reduced from 38.8 to 5.1, a reduction of 87%, by using the Forte Premium ULS Diesel Booster®. The estimated repair cost to rebuild the injectors on this truck would have been approximatly $4,000.
