Why do cars needs to have their oil changed? Will my car blowup if I don’t do it on time?
In: Engineering
Oil will break down over time due to high temperatures in the engine (known as thermal breakdown). Because of this, the oil isn’t capable of providing the necessary lubrication for metal parts after an extended period of use. Without lubrication, the moving joints in the engine will start rubbing against each other and cause premature wear. Oil also has a limited capacity on how much particulates it can hold. By not changing the oil, particles already in the oil will begin to settle and cause corrosion.
One of the biggest dangers of not changing your oil is sludge buildup. Sludge occurs when old oil begins to gel or solidify in an engine. When sludge begins to build up, oil isn’t able to flow freely through the engine and can cause oil starvation to crankshafts, bearings, camshafts, and other valve train components not be lubricated. In time, this can cause major damage to the engine and, in the worst situations, require an engine replacement or rebuild.
If the oil isn’t changed, your vehicle’s engine will start to have a lot of problems. The most common issue is that the parts in your engine will become too hot. This can cause the engine to run less efficiently, and as time goes on, it can cause the engine components to warp and wear out. The lack of lubrication between these parts will also contribute to these problems.
Eventually, if the oil is not changed, the entire engine will shut down and have to be replaced. This repair can cost thousands of dollars
