About US Gallons per 100 Miles

US gallons per 100 miles is the volumetric consumption figure displayed alongside mpg on the EPA Monroney fuel-economy label on all new US vehicles since 2013. A smaller number means a more efficient car. At $4/gal, gal/100mi × 4 gives the dollar fuel cost per 100 miles. Ranges: 1.5-2 gal/100mi for efficient compacts (50-67 mpg); 2.5-3.5 for mainstream sedans (28-40 mpg); 4-6 for crossovers/light trucks (17-25 mpg). 1 US gal/100mi = 3.785411784/1.609344 = 2.3521 L/100km.

About Microliters per Kilometer

A microliter per kilometer (µL/km) equals 10⁻⁴ L/100km - a unit reserved for laboratory engine testing and fuel cell research. A car consuming 7 L/100km corresponds to 70,000 µL/km, illustrating why µL/km is used only for scientific contexts: GDI injectors deliver 10-50 µL per injection event; engine oil blowby consumption is measured in 50-500 µL/km; hydrogen fuel cell prototype comparisons use µL-equivalent/km. Single-cylinder research engines log fuel use in µL/shot to map combustion efficiency across load sweeps. 1 µL/km = 0.0001 L/100km.
