  • What type of fuel can Our product be used in?


Our product can be used in all hydrocarbon fuel blends. These include gasoline, diesel, methanol, E85 and all fuel blends. When applied to methanol, it should be applied several hours before the methanol is used to ensure it is completely dissolved.



  • How long does our product take to dissolve in fuel?


Our product begins dissolving immediately and typically dissolves within minutes. Temperature of the fuel and agitation will affect the total time necessary to completely dissolve our product. You can add our product to your tank at any time, but for quickest dissolution add our product to your tank immediately before fueling. When using our product in race fuels, it is recommended to add our product to the fuel the day before you race.



  • Does your product change the octane levels of fuel?


Our products do not change octane levels or any other fuel specifications.



  • Can your product clog a fuel filter?


Our product dissolves 100% in the fuel and will not clog a fuel filter.



  • Will using your product void my engine warranty?


Our product will not void an engine warranty because it does not change any fuel specifications.



  • Does adding more than the recommended dosage of our product provide even greater power gains?


Not significantly. Always use our product in accordance with the recommended dosage.



  • Will adding your product to my fuel harm my engine?


No. Using our product in accordance with the recommended dosage will never harm your engine.



  • Will adding more than the recommended dosage of your product harm my engine?


No, however for best results always use the recommended dosage.



  • Can I add your product to a fuel tank with less than 15 gallons?


One dose of our product will treat any amount of fuel up to 15 gallons. This means that it can be used in one gallon or five gallons up to 15 gallons with each treatment.



  • What if my fuel tank holds more than 15 gallons?


Use two of our product treatments for any amount of fuel between 15 gallons up to 30 gallons.



  • How much horsepower will my engine gain by using your product?


It depends. There are many outside variables that affect horsepower like humidity, air temperature, altitude, emission controls, fuel, engine timing and other factors. The only way to determine your horsepower gains will be to dyno your car before and after treatment with our product.



  • Can I store your product in my car?


Our product is safe to store in your car but it will melt in temperatures higher than 140 F. Do not store in direct sunlight.



  • How often should I use your product?


For best results use our product every time you fill your tank. Consistent use of our product will help to clean and maintain optimal performance of the combustion chamber.



  • After I begin using your product, how soon will I notice a difference in performance?


Our product begins working immediately and with most vehicles the performance will be recognized right away. For immediate results, some vehicles may require a manual reset to the vehicle’s computer before a change in performance will be recognized. A reset can be achieved by simply disconnecting and then reconnecting the batteries(s) in the vehicle. As our product works to clean the combustion chamber, it may take several tanks of fuel to achieve maximum performance.
