jäännösoli

Jäännösoli is a Finnish term that translates to "residual oil" or "leftover oil." It generally refers to oil that remains in a container after the primary contents have been used or poured out. This can apply to various types of oils, including cooking oils, motor oils, and industrial lubricants. The amount of jäännösoli can vary greatly depending on the viscosity of the oil, the shape of the container, and how thoroughly it has been emptied.

In the context of cooking, jäännösoli might be the film of oil left in a frying pan after cooking, or the small amount remaining at the bottom of a bottle of olive oil. This residual oil can sometimes be reused, for example, in salad dressings or for greasing pans, though its quality may have degraded. For motor oils, jäännösoli refers to the oil that is not drained from an engine during an oil change. While modern engine designs aim to minimize this, a small amount always remains. This residual motor oil is typically mixed with fresh oil, and its presence is a factor in the overall performance and longevity of the lubricant. Disposal of jäännösoli, especially motor oil, is important to prevent environmental contamination, and specific recycling or disposal guidelines often apply.
