I don't understand why I should mix fuel by specific gravity. What is wrong with mixing by volume? The only reason that I can think of to use a hydrometer would be if I suspect that my nitromethane has been diluted and is not the advertised purity.
Not a thing, keep right on doing it, your fuel will be justfine. We've done it that way for years. My 32 year old Kraft .61 fired up on the second flip after 32 years in the box.
