A Pour Point Depressant (PPD) is an additive used in lubricants, particularly in engine oils and other petroleum products, to improve their flow characteristics at low temperatures. The pour point is the lowest temperature at which an oil or lubricant remains fluid enough to pour. By lowering the pour point, PPDs enable oils to function

Oil additives are chemicals added to lubricants to enhance their performance, protect machinery, and prolong the life of the oil itself. These additives provide various benefits, such as improving lubrication, reducing wear and tear, preventing oxidation, and maintaining cleanliness within engines and other mechanical systems. Here are some common types of oil additives and their
Greases are indispensable in certain applications where fluid lubricants cannot be contained effectively. Greases offer several advantages over oils in specific contexts. Grease seals out contaminants is well-suited for incorporating insoluble solid additives like molybdenum disulfide and graphite and excels in stop-start performance because it doesn’t drain away like oil. Most dynamic machine operations rely
Viscosity measures a fluid’s resistance to flow, reflecting its internal friction. High viscosity means the oil is “thicker” or “heavier,” while low viscosity means it’s “thinner” or “lighter.” For example, honey is thicker (higher viscosity) than water. Viscosity inversely relates to fluidity and changes with temperature. Hotter oil becomes thinner, reducing engine protection, while colder
