Carb Defender - Race Con centrate Case 6 x 6 oz.

The Carb Defender - Race Concentrate Case 6 x 6 oz. from DRIVEN RACING OIL is a professional-grade fuel system cleaner engineered for high-performance engines and race applications. Whether you're maintaining a turbocharged street car, prepping a competition vehicle, or restoring carburetor function on vintage equipment, this concentrate tackles fuel system deposits that degrade engine efficiency and throttle response. Six 6 oz. bottles provide enough treatment capacity for multiple fuel tanks or fleet maintenance, making it ideal for serious enthusiasts and shop professionals who demand reliable, repeatable results.

This race-spec formula works by dissolving varnish, carbon buildup, and fuel gums that accumulate in carburetors, fuel injectors, and intake valves over time. DRIVEN RACING OIL's concentrate is formulated to restore flow dynamics and combustion efficiency without compromising fuel quality or octane rating—critical for tuned engines running on the edge. The 6 oz. individual bottles allow precise dosing per tank, so you control treatment strength based on fuel condition and engine needs. This targeted approach prevents over-treatment while ensuring maximum cleaning efficacy in fuel-injected and carbureted systems alike.

Mechanics, race teams, and power enthusiasts benefit most from keeping this concentrate on hand for seasonal maintenance, post-storage revival, or pre-event fuel system flushing. Use one bottle per 12–15 gallons of fuel for light maintenance, or increase concentration for heavy carbon removal in neglected or high-mileage engines. Compatible with all gasoline engines—carbureted, fuel-injected, turbocharged, or naturally aspirated—the Carb Defender works as a standalone cleaner or complements other DRIVEN products in a comprehensive fuel system maintenance program. Store in a cool, dry location and shake well before each use to ensure uniform treatment.
