Gasoline fuel lubricity is key to reducing wear and energy losses from friction in engines. The High-Frequency Reciprocating Rig (HFRR) test protocol recommended for gasoline fuels has been modified to evaluate the wear and friction properties of additized fuels. Adapted from the American Society for Testing and Materials (ASTM) D6079 test for diesel lubricity and literature-based procedures developed for gasoline fuels, the protocol and hardware used in this study allow for differentiation of fuels with unique additive chemistries and varying additive treat rates (EPA-approved lowest additive concentration, LAC, or higher). Supplementing HFRR tests, measurements of acoustic emissions corroborate friction coefficient trends using different additized fuels. Anti-wear performance of fuels during engine tests was characterized by roller-follower pin wear and metal concentration in engine oil, further distinguishing LAC from alternate additized fuels. The engine tests and acoustic emissions measurements support HFRR observations that gasoline fuels with varying additive chemistries and concentrations can offer enhanced lubricity compared to fuels additized with basic LAC additives.
