This product is sold as a case containing 10 pints. Please note that it cannot be shipped to California or New Jersey. It's an amazing oxygenating power additive designed for gasoline and methanol fuels. Formulated as a powerful oxygenating additive, it contains 50% Nitropropane and 50% Koolinal® which acts as a blending and cooling agent. Koolinal® helps prevent detonation and pre - ignition. Using this additive can significantly boost horsepower and torque, and it also enhances throttle response and acceleration. Product Type: Power Additive. Recommended Applications: Suitable for both 2 - stroke and 4 - stroke stock and modified engines. Blends With: Gasoline, E85, Methanol. Directions: It easily blends with gasoline, methanol, and E85. To ensure optimal performance, take several spark plug readings to verify jet settings and adjust the spark plug heat range. A colder spark plug heat range is advisable. For 4 - stroke engines, start by using 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. You can use ratios up to 12 ounces per gallon with proper jetting, but always verify heat constraints. For 2 - stroke engines, start with 2 to 4 ounces of NITRO per gallon. Jet sizing may need to be increased up to 6 sizes. Higher ratios can be used, but make sure to check jetting and heat. Due to the large size and weight of this item, additional UPS charges apply.

Using this Klotz KL - 600 Nitro Power Additive is easy. First, know that it comes in a case of 10 pints and can't be shipped to California or New Jersey. For different types of engines, here's how to use it. For 4 - stroke engines, start by adding 3 to 4 ounces of the NITRO 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 make sure to check the heat of your engine. For 2 - stroke engines, start with 2 to 4 ounces per gallon and you may need to increase jet sizing up to 6 sizes. You can use higher ratios, but always check the jetting and the engine's heat. When you mix it with fuel, it blends well with gasoline, methanol, and E85. After adding it, take a few spark plug readings to make sure the jet settings are right and adjust the spark plug heat range. A colder heat range is better. Also, because this item is big and heavy, there will be additional UPS charges. Keep these things in mind, and your engine will run better with this additive.
