Question: What is pure methanol?
Answer: If it is sold as pure methanol, it is supposed to be well over 99% methanol. It is a baseline compound that should behave the same regardless of supplier unless it is mixed with something else such as a top end lube or it is contaminated. (more…)

Question: Can methanol be stored for a long period of time?
Answer: Methanol absorbs moisture. So if it is stored, it must be in a sealed container. Plastic is microscopically porous and does allow for methanol moisture contamination if it is stored a long time or (in some cases) if the container is dipped in an ice water bath to keep it cool on a hot day.
