Fuel Additives


Martin Marietta Magnesia Specialties provides magnesium oxide and magnesium hydroxide for use in fuel additive formulations.


MagChem MagChem MH 10

MagChem® magnesium oxides including MagChem® 30, 35, 40 and 50 are used to produce overbased magnesium sulfonates and magnesium salicylates that serve as fuel additives and motor oil detergents. MagChem®’s high purity, uniform calcination and fine particle size generate sulfonates and salicylates with high base numbers and good clarity.

MagChem® MH 10 LC and MagChem® MH 10 ULC magnesium hydroxide products with low calcium levels are used in the production of magnesium carboxylate fuel additives to treat heavy fuel oils and crude oils. MagChem® hydroxides generate carboxylates with high % Mg and without detrimental effects caused by high calcium levels which cause particle buildup on power gas turbine blades.

Common Applications

  • Magnesium sulfonate
  • Magnesium salicylate
  • Magnesium carboxylate
