Your car’s oil warning light tells you when your oil pressure is dangerously low. Often mistaken for an indication of the oil level, the light actually activates when there isn’t enough pressure to inject oil into the cylinders in the egine. Without the lubrication the oil provides, the cylinders can be damaged, leading to the need for a new engine. The oil warning light can come on as a result of several common problems.
Low Oil Pressure
Low oil pressure is the most common reason the oil light in your car will come on. A sensor in your engine determines whether oil is being pumped hard enough to channel through narrow holes in the pistons and other engine parts. Without enough pressure, the oil will not reach necessary areas of the engine. The friction of the engine parts rubbing against one another will lead to heat and abrasion, quickly damaging the engine beyond repair.
