Things you need to know before you begin: You'll need a pair of gloves (nitrile, latex, or rubber) and measuring device. Be careful not to let the catalyst touch your skin. Please use one of our approved measuring devices or if you want to use your own device, it should be glass or fluorinated plastic.

Dose at every fuel stop. Once you've filled the tanks, dose out the correct amount of catalyst for each tank. Measure out one ounce per every 25 gallons of diesel fuel. Use the back of the bottle for reference. For gasoline engines, the correct dosing is one ounce for every 30 gallons of fuel, or one ml per gallon. The catalyst is designed to mix itself. That's it!
