Engine oil is an essential component for the proper functioning of your car's engine. It lubricates the moving parts inside the engine, keeping then from wearing out because of excess friction. Your car needs regular oil changes to remove the dirty, worn oil and replace it with new oil that will replenish your engine. Usually, the oil is designed to cover a specific number of kilometres before you need to change it. Sometimes, this doesn't happen, and you find yourself changing the oil too many times. What makes your car use so much oil? Here is a look at the possible causes of the problem with some solutions:
Bad Positive Crankcase Ventilation (PCV) Valve
The crankcase makes up a big part of the engine. It houses many of the engine's moving parts that need protection from excess heat and friction when the car is running. As time goes by, pressure builds in the crankcase following the energy-producing reactions in the engine. Combustion gases move forcefully across the piston rings and create pressure zones inside the crankcase. The reaction is referred to as a blowby. Your engine uses a PCV valve to relieve pressure from the crankcase.
A malfunctioning PCV system causes pressure to accumulate in the crankcase, forcing oil past the gaskets and the seals. Leaks result from this and lead to excessive oil consumption. Usually, the check-engine light will come on when the oil levels are low, followed by rough running and backfiring. You need to check into a repair centre to replace the valve.
The Oil Is Not Good Enough
Pay attention to the quality of oil that goes into your car's engine. Using the wrong type of oil means that the lubricant in the engine cannot handle the levels of pressure, compression and heat inside the engine. The oil will not lubricate the engine components adequately, causing burn-ups and the need for more oil. It is advisable to consult a mechanic before settling on a specific type or brand of oil. Some manufacturers also inscribe the recommended oil on the oil inlet cap to remind you about what you should use.
Worn Gaskets and Piston Rings
Worn gaskets and piston rings allow oil to seep through them as it circulates through the components. The oil enters the combustion chamber and burns up instead of lubricating the engine parts. It is only a matter of time before the oil sensors go off and demand more oil.
Excessive oil consumption issues are easily fixable provided you pay attention and address them as soon as possible. Failing to do so damages your engine even further.
