RE: making fuel
Why don't you calculate that by the first principle that all of us have studied at school? I've been mixing my fuel that way.
Here's my mixture:
18% oil and 2% nitro(we run on low nirto here koz its extremly expensive $200 per gal!)
Lets say 100% ------> 6000 cc (5000cc methanol + 1000cc oil)
then 2% -------> (6000/100)*2 = 120cc nitro.
Isn't that simpler? You just have to change the 2% to the % you require!
Hope it helps.
