Oil Filter Clogged: A clogged oil filter can restrict oil flow to the engine, causing the oil light to come on. Replace the oil filter as soon as possible.
Oil Pump Failure: The oil pump is responsible for circulating oil throughout the engine. If the oil pump fails, the engine will not receive any oil and serious damage can quickly occur. This is a serious problem that requires immediate attention from a mechanic.
Engine Problems: In some cases, the oil light can come on due to a problem with the engine itself. For example, a worn out engine may have increased clearances that allow oil to leak out, resulting in low oil pressure. This type of problem will require major engine repairs.
