scroll down to "custom fuel blending workshop and click on it.
scroll down to bottom of page and click on either button depending on what you want to do. This will send you to a page where you can list the amounts in your present fuel and the percentages you want to obtain and it will figure it out for you. To bad it's a car site, but the formula thing works.
Thanks, but I don't think that worked. Unless I'm missing something on the input fields, but they're pretty straight forward. Here are the results. Maybe I'll just get a gallon or two of the fuel I need.
According to the figures you just gave us, your current fuel has, 15% nitro content and 18% oil content, leaving 67% methanol.
You have indicated that you wish to increase your nitro content by -10% to a new total percentage of 5% and your oil by 2% to a new total of 20%
In order to accomplish this you will simply need to add -13.5 ounces of nitro and -0.2 ounces of castor/synthetic oil to your 128 ounces of fuel. (What the?)
When you're done, you should end up with 114.3 ounces (0.89 gallons) of newly blended, custom fuel.
