Lube oil, also known as lubricant, is a substance used to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. Lubricating oil is used in motorized vehicles, where it is known specifically as motor oil and transmission fluid. Here are some key points about lube oil:

• Lube oil is typically composed of 90% base oil (most often petroleum fractions, called mineral oils) and less than 10% additives.
• Vegetable oils or synthetic liquids such as hydrogenated polyolefins, esters, silicones, fluorocarbons, and many others are sometimes used as base oils.
• Additives deliver reduced friction and wear, increased viscosity, improved viscosity index, resistance to corrosion and oxidation, aging or contamination, etc. .
• There are two basic categories of lubricating oil: mineral and synthetic. Mineral oils are lubricating oils refined from naturally occurring crude oil. Synthetic oils are lubricating oils that are manufactured.
• Lubricating oils of different viscosities can be blended together, and it is this ability to blend them that makes some oils so useful.

It is important to note that while lube oil is commonly used in vehicles and machinery, it is not recommended for use as a personal lubricant during sexual activity. Oil-based lubricants can increase the risk of rips and tears in latex condoms and can also be associated with higher rates of Candida, a type of fungus that’s responsible for yeast infections.
