RunGreen’s X-Carbon tested in Diesel, Gasoline (Petrol), Kerosene and Marine Gasoil by AmSpec
"AmSpec is a world-respected testing and certification company for fuel, so we are pleased to add their positive test results of X-Carbon to our armoury of proof that X-Carbon is safe to use and does what it says on the bottle. These tests show that the addition of X-Carbon does not affect the required specification for Diesel, Gasoline (Petrol) and, for the first time of testing in the UK, Kerosene and Marine Gasoil."
