How much oil does a typical grease contain?

A typical grease contains around 85% oil, which is why this option is the most accurate. Grease is essentially a lubricant that combines base oil with a thickening agent, along with additives. The majority of the volume in grease is indeed composed of the base oil, which provides the necessary lubrication properties. The thickener, generally present at around 10-15%, serves to give the grease its semi-solid form, allowing it to stay in place and provide effective lubrication under various operating conditions.

By understanding this composition, one can appreciate the importance of both the oil content and the thickener’s role in maintaining the grease's consistency and performance. Additionally, certain applications may require grease with specific properties, but the fundamental makeup of grease remains consistent across most types.
