Answer by  LeheckaG (1826)

Gasoline's-octane-rating can be increased by mixing high-octance-additives into your-gasoline, which is what oil-refineries/terminals do when blending higher-octane-gasolines. Higher-octance-gasoline decreases "knocking" or early/pre-detonation (especially at higher-speeds/operating-temperatures), but does NOT necessarily increase fuel-economy/gasoline-mileage (unless you race/speed all-of-the-time). For better-fuel-economy: Change your-air/oil-filters & grease/lubricate-bearings; Get an-OBD-II-code-scanner (some have real-time-fuel-economy-statistics) to find accelerator-pedal/speed/transmission-sweet-spot; Accelerate-slowly/maintain-CONSTANT-speed/COAST/decelerate-slowly/brake-sparingly.
