• Manganese fuel additive safe


    An international company clarified that the presence of manganese in fuels in the Philippines has neither adverse effect on vehicles nor the environment.

    This after earlier reports stated that Automobile Central Enterprise Inc. (ACEI), the official local distributor of Volkswagen in the country, claimed that they have yet to bring gasoline-powered vehicles because of the presence of manganese-based additives in country’s fuels.

    In a news forum, Afton Chemical Corp. marketing director John Walsh said that MMT (methylcycloentadienyl manganese tricabonyl), a lead replacement additive, has already been in the country for more than a decade to help produce clean, environmentally beneficial, high-octane gasoline compliant to the Clean Air Act standards.

    Walsh cited that in December 2012, the US Agency for Toxic Substances and Disease Registry concluded that new manganese health science, including that developed by Afton, merited increasing the standard for the amount of manganese that can be safely inhaled.

    According to him, the amount of MMT added to fuel is much lower compared to other additives such as lead-based additives.

    He said that fuels are only blending 18 parts per million—equivalent to two drops every five liters of gasoline.

    He also cited that manganese—the 12th most abundant element and can also be found in soil and food—pose “no health hazard” based on US EPA standards.

    Further, Walsh said that a study made by US EPA in 1994 that was reaffirmed in April 2013 showed good news for the manganese-based additive. Based on its conclusion, MMT “will not cause or contribute to the failure of any emission control device or system.

    He added that they are willing to discuss to ACEI about the latter’s claims on the issue.

    For their part Independent Philippine Petroleum Companies Association (IPPCA) President Fer Martinez backed Walsh’s claims.

    ”Members of the IPPCA which uses manganese additives to achieve a better octane rating assures that there is no health-related concerns that are being breached,” he told The Manila Times after the forum.
