High-octane methanol additive

Used in as an additive to motor gasolines (up to 55% of the volume). It cannot be used directly as a fuel due to the high content of olefins in the composition. OCHI 96, OCHM 82.

It is optimal to use this additive as an aromatics, in order to eliminate the odors of other additives and to stabilize the octane number.

Can be used as a solvent.
