The most accurate way of mixing the fuel at home, use a inexpensive kitchen digital scale. I have found this is the best way to mix fuel and to compare prices with factory blends. New improved version now includes cost calculation for instant comparison! And it’s FREE! Home Brew Buddy is a free calculation utility designed for all Win9x / ME / XP / NT40 / W2000 platforms. It allows you to compute the amounts of ingredients required to mix methanol based model fuel at a specified temperature. Home Brew Buddy allows the modeler to leverage the accuracy advantages and ease of mixing afforded by weighing ingredients into a method of mixing ideally suited to individual or batches of small quantities. Most inexpensive digital kitchen scales have a range of 2kg and an accuracy specified by two parameters. The first parameter is the span error and is expressed as a percentage of full scale. Typically this is ¼% which, in the case of the 2kg scale, is 5g at full scale. The other parameter is a resolution or digitizing error, whichever is the larger. In the case of kitchen scales this is equal to the minimum resolvable display value which is usually 1g. Measuring a weight of 500g would therefore incur a maximum expected measurement error of 1+5/4=2.25g. This accuracy is a great deal better than could be expected by measuring by volume and is obtained with ease using inexpensive equipment. All of these inexpensive scales have a Tare facility that enables the ingredients to be added directly to the mixture and thus eliminate the problems of residual material, such as oil, remaining in the measuring equipment.
