VP M1 Racing Methanol fuel has a 99.95% minimum purity. It’s the highest purity available in the United States. M1 helps engines run cooler compared to standard methanol blends. They’re also subject to less corrosion when compared to standard methanol blends.  Furthermore, we use only lined drums, which prohibit rust, corrosion and metal deposits that can contaminate fuel delivery systems. We recommend M1 for all methanol-legal racing applications.
