The invention provides a lubricating oil composition comprising: a base oil; and coated particles made of nanoparticles and phosphonic acid coating at least a portion of the surface of the nanoparticles.

The engine lubricating system can become contaminated with carbon deposits and sludge. Sludge is where the combustion by-products that have entered the oil base saturate this oil base, thus forming a thick carbon rich substance. Sludge is not wanted within the engine. Sludge and or carbon deposits in the motor oil cause problems. Such carbon deposits form in the motor oil from heat, pressure, and namely combustion gases that have leaked pasted the piston rings. Turpentine and terpenes, hereafter referred to as “terpenes”, have shown that these chemicals can breakdown carbon which has been deposited within the engine's oil base.

This invention relates to overbased calcium sulfonate complex grease compositions prepared without boric acid and alcohol promotors containing anti-wear, anti-friction, thermal & oxidation stability additives.
