OIL FRICTION MODIFIERS IMPROVE MILEAGE MORE THAN VISCOSITY REDUCTIONS

Researchers from Acheson Industries have conducted track tests using EPA procedures to determine the influence on fuel economy of oils with a graphite additive. Viscosity differences in conventional oils did not demonstrate consistent differences in fuel economy. The addition of one weight percent graphite in SAE 5W-30 oil gave a 6.4% improvement in fuel economy during the urban driving cycle and a 5. 8% improvement during the highway cycle. The 5W-30 friction modified oil gave an improvement in fuel economy on the order of 5.5% over conventional SAE 10W-40 oil. A comparison of single grade SAE 30 oil with and without the graphite additive demonstrated a less dramatic improvement in fuel economy but it did provide a 2.5% improvement in the urban cycle with fresh oil.
