The Klotz KL - 600 Nitro Additive is a top - notch oxygenating power enhancer crafted specifically for gasoline and methanol fuels. This additive is formulated to unlock the maximum potential of your engine, whether it's a stock or modified 2 - stroke or 4 - stroke engine. It contains 50% Nitropropane and 50% Koolinal®. Koolinal® acts as a blending and cooling agent, effectively resisting detonation and pre - ignition, ensuring a smooth and powerful engine performance. Using this additive can significantly increase horsepower and torque, giving you better throttle response and acceleration. It blends seamlessly with gasoline, E85, and methanol. Please note that this product cannot be shipped to California or New Jersey. For 4 - stroke engines, start with 3 to 4 ounces of NITRO per gallon. You may need to increase jet sizing up to 4 sizes. For high - compression engines, retard the timing by 2 degrees. Ratios up to 12 ounces per gallon can be used with proper jetting, but always verify heat constraints. For 2 - stroke engines, start with 2 to 4 ounces of NITRO per gallon and be prepared to increase jet sizing up to 6 sizes. Higher ratios can be used, but check jetting and heat regularly. Dyno tests show substantial power increases when using Klotz Nitro.

Here's how to use the Klotz KL - 600 Nitro Additive. First, it can be blended with gasoline, methanol, and E85. When you start using it, take several spark plug readings to make sure your jet settings are right and to adjust the spark plug heat range. We recommend using a colder spark plug. For 4 - stroke engines, begin by adding 3 to 4 ounces of the additive per gallon of fuel. You might need to increase the jet sizing up to 4 sizes. If you have a high - compression engine, remember to retard the timing by 2 degrees. You can use up to 12 ounces per gallon, but you have to check the heat situation. For 2 - stroke engines, start with 2 to 4 ounces per gallon and you may need to increase the jet sizing up to 6 sizes. You can use higher ratios, but always check the jetting and heat. Also, keep in mind that this product can't be shipped to California or New Jersey. There aren't any special maintenance steps for the additive itself, but always make sure your engine is in good condition for the best results.
