Do methanol fuel and combustion improver need to add sodium hydroxide?

No need. Methanol fuel additive is a strong combustion-supporting agent, so there is no need to add sodium hydroxide to methanol fuel additive. Methanol fuel combustion improver is a kind of high-strength oxidant developed on the basis of alcohol-based fuel heat stabilizer, which has the functions of one-time combustion, multi-stage reaction and double heat release.
