An engine flush is a process that uses chemicals to remove sludge, deposits, and other contaminants from the inside of an engine’s lubrication system. This service typically involves adding a cleaning solution to the engine oil, running the engine for a short period, and then draining the old oil along with the dislodged contaminants. The process concludes with replacing the old oil filter and refilling the engine with fresh oil. A simple oil change removes the existing oil and filter, while an engine flush is a more intensive cleaning process aimed at addressing accumulated buildup within the engine.
Maintaining a clean engine contributes to optimal performance and longevity. Internal engine cleanliness promotes efficient heat transfer, reduces friction between moving parts, and helps prevent premature wear. Historically, engine flushes were often recommended at more frequent intervals. However, with advancements in oil technology and modern engine manufacturing, the need for frequent flushes has diminished, especially for vehicles maintained according to manufacturer recommendations. In some cases, an engine flush can be beneficial for older vehicles or those with a history of neglected maintenance. However, it’s crucial to consider the potential risks and consult a qualified mechanic to determine whether a flush is appropriate for a particular vehicle and its condition.
