jalavahetust

Jalavahetus, also known as an oil change, is a routine maintenance procedure for internal combustion engines. It involves draining the old engine oil and replacing it with new oil and a new oil filter. This process is crucial for the longevity and performance of an engine.

Engine oil lubricates moving parts, reduces friction, and dissipates heat. Over time, oil degrades due to heat, oxidation, and contamination from combustion byproducts and wear particles. This degradation reduces its lubricating properties, leading to increased wear and potential engine damage. The oil filter, which removes contaminants from the oil, also becomes clogged and less effective.

The frequency of jalavahetus varies depending on the vehicle manufacturer's recommendations, the type of oil used, and driving conditions. Generally, it is recommended every 5,000 to 10,000 miles or every six months, whichever comes first. Severe driving conditions, such as frequent short trips, stop-and-go traffic, or towing, may necessitate more frequent oil changes.

Performing a jalavahetus typically involves raising the vehicle, locating the oil drain plug, and draining the old oil into a suitable container. The oil filter is then removed and replaced, and the drain plug is reinstalled. New oil of the correct type and viscosity is added to the engine through the oil fill cap. It is important to dispose of used oil and filters properly, as they are hazardous waste. Many service centers offer jalavahetus services, or it can be performed by individuals with basic mechanical knowledge.
