The specific gravity of PURE methanol is .792 at 68 degrees. That of course changes if there are any additives at all in it. A simple hydrometer is cheap and effective (Buy the 6" version, easier to work with) and you can use it in the same 100 ml cylinder you use to cc your heads.



can it be used to check % of ethanol? Say 78%-85%?
Saw one at McMaster-Carr, $16= .650-1 spec. gravity.
