With a 92 octane rating and an ethanol-free and oil-free formula, Harvest King 4-Cycle Fuel burns cleaner, helps extend engine life, and improves throttle response while delivering dependable power. Engineered for carburetors and fuel injection systems in small engines, this high-performing fuel keeps your equipment running at peak performance.
