Your safe, proven, flexible octane solution
mmt® (Methylcyclopentadienyl Manganese Tricarbonyl) Fuel Additive is an organic manganese compound that is easy and safe to handle, and compatible with all fuels. mmt® is used at very low treat rates (ppm level); just a few drops added per gallon of gasoline can increase octane by 1 or 2 octane numbers. It has been utilized for over thirty years as an efficient octane improver in unleaded gasoline and in every application has a well-proven record of acceptable performance in consumer use.
mmt® increases octane levels and helps refiners to beneficially alter fuel composition to meet the stringent environmental and fuel quality specifications that are so crucial to reducing emissions and energy consumption. Refining and blending economics are greatly improved by allowing more efficient unit operation and blending of lower cost components. mmt® also helps vehicles maintain their emission performance over their useful life by protecting catalysts and oxygen sensors from degradation.
The main component of mmt® is manganese, an element that occurs naturally in our environment. Much is known about manganese and its potential impact on public health, whether due to use of mmt® or from other natural or industrial sources. mmt® is one of the most comprehensively tested fuel additives in history. Through repeated evaluation, mmt® has demonstrated no identifiable risk to public health or welfare. The use of mmt® has been reviewed by government agencies and approved for use around the world. Over 150 refiners in 45 countries in Europe, Africa, Asia, Central and South America, as well as the United States and Canada, currently use mmt® to produce high quality gasoline, providing fuel for millions of cars with over a trillion miles of trouble free operation.
