A universal additive for fuel and lubricants contains C2-C4 alcohols, carbamide, boric acid, acrylic compounds, and water. The additive allows for more complete combustion of liquid and solid fuels, as well as reduced fuel consumption and fewer harmful emissions. In lubricating oil compositions, the additive reduces wear on the friction surfaces of engines, and also reduces fuel consumption.

The present disclosure provides a fuel composition that includes hydrocarbon-based fuel boiling in the gasoline or diesel range; an amine-based detergent given by formula R.sub.1—O—(CH.sub.2).sub.m—NHR.sub.2, wherein the additive is present in about 10 ppm to about 750 ppm by weight based on total weight of the fuel composition; wherein R.sub.1 is a hydrocarbylgroup having 8 to 20 carbons, R.sub.2 is hydrogen or (CH.sub.2).sub.nNH.sub.2 moiety, and wherein m, n are independently integers having a value of 3 or greater; and one or more nitrogen-containing detergent.

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.
