What Cleaner, Lighter, Faster Means

Cleaner

Cleaner refers to how the fuel is made. Base Racing Fuels are precision blended by weight using all-stainless equipment, allowing exact formulas and consistent results from batch to batch. We use only the highest-quality, cleanest component stocks, producing a fuel that burns consistently and maintains engine efficiency.

Lighter

Lighter refers to the quality of the cuts off the refinery. Lighter fuel components are inherently cleaner and more refined. BASE Racing Fuels are formulated using the narrowest cuts off the refinery, heavier, lower-grade cuts commonly used to reduce cost. Lighter fuels vaporize more efficiently and respond faster under load.

Faster

Faster is the result of precision. By combining cleaner blending methods, lighter components, and application-specific burn rates, BASE Racing Fuels allow engines to perform at their highest potential. Choosing the correct fuel for the conditions optimizes combustion, controls engine temperatures, and delivers consistent power.
