Engine oil is a substance that lubricates car engines. It aims to minimize the friction occurring between cooperating moving motor components. Thanks to engine oil, a thin layer of oil forms between these elements. Good quality oil will ensure optimal lubrication under various conditions while driving. It all depends on how much viscosity engine oil will have at start-up.
Modern oils are required to counteract the appearance of rust on individual metal parts of the engine. It also aims to prevent the deposition and accumulation of dirt in the interior of the engine. Thus engine oil should be changed regularly
