A seized engine is one of the most serious, if not the most serious, and costly malfunctions that may affect your car's engine.

There are two main causes of a seized engine: a lack of engine oil, which causes insufficient lubrication of moving parts, or an insufficient amount of coolant, which causes the engine to overheat.

Cold starts harm the engine, no matter the outside temperature. However, the lower the outside temperature, the longer it takes for the engine to warm up to the operating temperature, meaning that these adverse effects affect the engine for a longer period.

Today's article will focus on what happens in the engine during warm-up to its operating temperature.

The oil pressure indicator warns of a drop in engine oil pressure. This light comes on if the oil pressure in the engine does not reach the required level. If the lubrication system is in order, the oil pressure warning light will come on after turning the key to the second position, informing us that there is no pressure in the engine.

However, after starting the engine, the pressure will increase, and the warning light will go out. Beware that if the oil pressure indicator lights up even after starting, it means that there is a lack of engine oil in the engine or there is a malfunction in the lubrication system.

A lit oil warning light warns of a severe problem you should not underestimate. But what is the reason for this warning light to come on?

We will answer this very frequently asked question in today's article.
