Those beads are molecular sieves, they work by admitting molecules of a particular size and most typically are designed to trap water. https://ledab.ca/4a-molecular-sieve-2lb-bag/

Bullet point: "Dehydration of highly polar compounds, such as methanol and ethanol".

Re: Home brew fuel recipe

Dry some 3A molecular sieve, add a good 10% by weight to the fuel jug, then let it sit for 5 days to absorb moisture. Strain out the sieve, use the fuel, wash and reactivate the sieve for next time.

Re: Home brew fuel recipe

36.1 ounces of castor oil to 128 ounces of fuel. Does this sound right for 22% oil content?

Re: Home brew fuel recipe

128 ounces of fuel with 22% oil would have 22/100 x 128 ounces = 28.2 ounces of castor oil. How did you come up with 36.1?

Ignore density and weight, use liquid volume measurements, and the math is rudimentary.

Again: all fuel formulas/percentages are volume, not weight.
