KLOTZ OIL Nitro Additive - 16 U.S fl oz. - Case of 10 KL-600

If you're running a modified engine or pushing a stock build to its limits, fuel octane rating becomes your ceiling—until now. KLOTZ OIL Nitro Additive is a concentrated oxygenating power booster formulated to unlock additional horsepower by improving combustion efficiency and resisting detonation. Mixed into gasoline or methanol, this additive delivers measurable performance gains that show up on the dyno.

The formula pairs 50% nitropropane with 50% Koolinal™, a proprietary cooling agent that stabilizes combustion and prevents pre-ignition under extreme boost or high-RPM stress. Each case contains ten 16-fluid ounce cans—enough to treat multiple tanks or keep your fuel system optimized throughout the racing season. Made in the U.S.A., KLOTZ Nitro is trusted by racers and engine builders who demand reliability alongside performance.
