MAZ conforms to the Worldwide Fuel Charter (WWFC) Standards and Registered with

U.S. Environmental Protection Agency (EPA)


Intertek confirms that diesel dosed with MAZ complies with the specifications of Australian Fuel Quality Standard, which is also in accordance to the fuel specifications of the Worldwide Fuel Charter (WWFC).

The Charter was first established in 1998 to increase understanding of the fuel quality needs of motor vehicle and engine technologies and to promote fuel quality harmonization worldwide in accordance with those needs. Establishment of guidelines set by the Worldwide Fuel Charter simplifies the process of determining the suitability of additives and fuels for automotive engines.

Most members of OEMs are signatories to the Worldwide Fuel Charter, which states that the fuel provided shall not void OEM engine warranties, if they are within the specifications as required by WWFC.

MAZ complies with the standards set by the Worldwide Fuel Charter and is safe for all engine warranties.

MAZ products are also approved by the U.S. Environment Protection Agency (EPA) and can be used to treat all fuels including gasoline, diesel, ethanol, biodiesel, ULSD, marine bunker fuel, and recycled transformer oil.
