oil

An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving"). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.
The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents.

    Can a new oil tank install be DIYed?

    Hi. Asking for a relative whose neighbour seemingly DIYed an oil tank replacement. She was aware of 'oil' smells at regular times in the weeks following this, although that has since died down. Is there a way of checking whether the installation was registered, a bit like boiler installs? Thanks.

    Does it harm an oil boiler if it is only used occasionally?

    Hi We're reviewing our heating options... One option is to mainly heat the house with wood, and keep our old oil boiler as back up and for occasional use. It's a Worcester Danesmoor 20/25 and is probably around 20 years old. Do oil boilers only wear out from use? Or can there also be issues...
