Seven major functions of methylcyclopentadienyl manganese tricarbonyl
(1) Increase the octane number of gasoline
Add one ten-thousandth of MMT to gasoline with a manganese content not exceeding 18mg/L, increase the octane number of gasoline by 2 to 3 units. 
(2) Improve the automobile power and reduce fuel consumption
Pursuant to the Engine Frame Test conducted by the Energy Utilization Monitoring Center of the Ministry of Transport's Automobile Transport Industry: Compared with 90# unleaded gasoline without MMT, 90# unleaded gasoline with MMT has improved engine power performance and reduced fuel consumption. 
(3) It has good compatibility with oxygen-containing components such as MTBE and ethanol 
MMT, MTBE and ethanol have good additivity in the improvement of octane number, which facilitates to product high-grade gasoline. It can both meet a higher octane number, and avoid excessive decline in vehicle power performance caused by excessive use of MTBE. This can meet the national standard of oxygen content not exceeding 2.7%. 
(4) Reduce the emission of pollutants in vehicle exhaust
Compared with unadulterated 90# unleaded gasoline, 90# unleaded gasoline with MMT has a 17.7% decrease in CO and a 18.2% decrease in HC in engine exhaust. 
(5) It improves the catalytic converter of automotive exhaust gas
Phosphorus is reputed as a catalyst toxin. When MMT burns, it can remove phosphorus and reduce deposits on the catalyst. Therefore, using fuel with MMT can extend the catalyst's lifespan, maintain a high conversion rate, thus converting harmful gases and reducing pollutant emissions. 
(6) Improve oil refining operations
● Reduce the harshness of the operation of the reforming unit
● Decrease the aromatic hydrocarbon content in gasoline
● Reduce the olefin content in gasoline
● Reduce the demand for crude oil
(7) Make the oil blending more flexible
Gasoline products of various specifications can be extracted by rationally using MMT, MTBE, reformed gasoline, catalytic gasoline and straight-run gasoline.
