X-Carbon it is entirely safe to use in engines, supported by extensive testing and analysis over many years, certification and use.

Many years of testing and proof: Hundreds of thousands of litres of X-Carbon have been widely used in many different engines with gasoline/petrol, diesel and kerosene fuels with no known issues. There have never been any reports of any form of damage caused to any engine that has used X-Carbon/Oxytane as manufacturered by AMJ Chemical Inc, since it was first used in the USA in 2004, in Africa since 2008 and in Europe since 2019.

Same ingredients as in petrol/diesel: X-Carbon is manufactured only by AMJ Chemical Inc in the USA where it is registered as Oxytane. Unlike additives designed to chemically alter the fuel, X-Carbon is made of the same 3 petro-chemicals already used in fuel and so is undetectable when added to diesel, kerosene or gasoline/petrol (for details see FAQs).  D-975 and EN590 tests show zero change in fuel specification (see Intertek EN590 test). X-Carbon/Oxytane is registered with USEPA and considered a pure fuel.

X-Carbon/Oxytane’s certification and testing includes:

‍

AmSpec is the world's leading provider of testing, inspection, and certification services in oil and petrochemicals. When AmSpec added X-Carbon to petrol/gasoline, diesel, kerosene and marine gasoil in October 2023, they found that the fuels still met the required specifications for the tests performed. When fuel specifications are met, quality is assured and it will not cause harm or be unsafe when used in the appropriate engine. Tests also reported with the addition of X-Carbon there was a reduction in carbon deposits and air in the fuel, supporting the claims that lead to the benefits of using X-Carbon.

‍

EN590 certification: Intertek's ITS Testing Services (UK) Limited certification is a standard published by the  European Committee for Standardization that describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the European Union and several other European countries. In July 2014 Intertek certified that AMJ Chemical Inc's product Oxytane, known as X-Carbon in the UK/Europe, met its EN590 specification.

‍

Registered with the US Environmental Protection Agency (US EPA) for both gasoline/petrol and diesel: registration number: 25732001. This means it has been assessed and registered as safe to use and does what it claims. X-Carbon/Oxytane® is defined as “substantially similar” to gasoline/petrol and diesel for the purposes of the Clean Air Act, where it distinguishes which fuels and fuel additives are prohibited by the EPA.

‍

‍Dosage: Generally it is recommended that 10ml of X-Carbon/Oxytane is added per 50 litres of fuel, and if more is added it has no detrimental effects.
