Hyundai Sonata is a famous car due to its beautiful design and excellent features. The issue of burning oil comes in its 2015 model due to damage to several components.
Why is my 2015 Hyundai Sonata Burning Oil? The 2015 Hyundai Sonata burns oil due to less lubrication of engine components, carbon deposits, incorrect viscosity, and the problem with a positive crankshaft ventilation valve. The engine also consumes more oil due to damaged seals, faulty pistons, and defective valves. In addition, you can face this problem due to lack of maintenance, damaged air filters, and faulty piston rings. The blue color smoke and check engine light are the indicators of the burning oil.
You cannot ignore the issue of burning oil. The uneven smell comes from the engine because oil also gets burnt with air and fuel mixture in the combustion chamber.

What causes the 2015 Hyundai Sonata to Burn More Oil?
Many complain that their new Hyundai Sonata consumes more oil, which is not normal. Here are the main causes:
Less lubrication of the engine
Several parts of the engine work together to perform their specific functions. These parts are lubricated with motor oil to reduce the chances of friction and wear and tear in these components.
The high friction between these parts due to less lubrication is problematic. The engine consumes more power to run these components.
The high power means more fuel consumption for working with less lubricated engine parts. You can resolve the issue by appropriately lubricating several parts with a high-quality lubricant.
The use of lubricants also increases performance and fuel efficiency.
Damaged gaskets and seals
Gaskets are the essential material that is useful to seal the two surfaces in the engine compartment. These small accessories are made up of plastic material.
The gaskets and seals in this area get damaged due to temperature changes. Exposure to high temperatures and overheating cause the melting of these gaskets.
The valve seals get damaged, and cracks also come into them. The worn-out gaskets and valve seals cause oil entry into the combustion chamber.
The valve prevents the entry of oil into the combustion chamber. As a result, the oil that enters this chamber starts to burn, and your car consumes more fuel.
You can fix it by changing the damaged gaskets and seals.
Deposit of carbon and oil
Sometimes the carbon starts to build up o various parts of the engine. The accumulation of this black soot cause problem with adequate ignition.
The carbon layer causes more air to enter the combustion chamber.
The black soot of carbon residues starts to build up when your vehicle becomes old. Therefore, it is better to remove the carbon residues from engine parts.
Faulty piston rings
The piston ring is the seal between the piston wall and cylinder wall. It acts as a regulatory system and maintains oil consumption.
In addition, it also protects the excessive oil entry into the combustion chamber. As a result, the piston rings become damaged after some time and cause problems.
The gap between them and the cylinder wall causes the entry of excessive oil into the combustion chamber.
When it enters the chamber, it starts to burn in the chamber and reduces the fuel economy.
Lack of maintenance
Every vehicle needs proper maintenance and regular service to perform best. The consumption also depends on your driving style and the load of the cargo capacity.
The mechanical stress due to damaged parts also causes this problem. You can face an issue if you are not regularly maintaining your car.
It is necessary to service your vehicle every 4 to 6 months to maintain the working of its several parts.
Damaged oil filters
These filters are present in the engine compartment to reduce the impurities and contaminants in the fuel. The damaged or clogged filters directly affect the performance of your vehicle.
In addition, the accumulation of dust, dirt, and grim also make these filters faulty. The engine uses more power for ignition due to blocked filters.
You have to clean the filters when you see the presence of dust. Your sonata also burns more oil due to the damage to oil pans.
Inappropriate viscosity of oil
The viscosity depends on the quality and service stations. The high-octane oil from the best service stations is thick enough and provides extra mileage.
The ones with less octane are thin and comparatively less viscous. The thicker ones burn more and eventually decrease the fuel economy.
Moreover, the thin oil is consumed in large amounts due to its viscosity.
Problem with PCV valve
The PCV valve is known as a positive crankshaft ventilation valve. The primary function of this valve is to remove the entrapped gasses.
It removes the gasses that are stuck in the crankshaft. The fresh air enters the system after exiting of entrapped air crankshaft.
Sometimes the PCV valve becomes faulty and sticks. The stuck valve creates excessive pressure that can damage the seals and valves of the engine.
The seals become damaged due to high pressure in the components. The malfunctioning in this part throws off the excessive amount of air and fuel for combustion.
You can fix the issue by protecting the valve from oil contamination. In addition, replace the valve when it completes its lie interval.
What happens due to the burning of more oil in Hyundai Sonata?
The burning of oil is damaging for your car, and it can also increase your service cost. Therefore, you should timely take notice to cope with the situation.
Wear and tear of engine parts
The burning of excessive oil by your vehicle damages the engine and its components. In addition, it decreases the life of several components.
Moreover, the leakage in the engine greases its components and causes dust on its surfaces.
The excessive oil and lubrication also put pressure on the crankshaft.
Excessive oil in the exhaust system
The damaged valve, pistons, and seals cause oil entry into the exhaust system. The accumulation is damaging to the components of the exhaust system.
It also affects the working of the catalytic converter and cannot function well. The faulty catalytic converters cannot convert harmful gasses to less harmful gasses.
The accumulation into the exhaust system is harmful to passengers and drivers. In server cases, the particles also cause the complete failure of the catalytic converter.
Low fuel levels
The excessive burning of oil decreases the levels of fuel in the tank. As a result, your car consumes extra gallons of oil as compared to a normal routine.
The average person cannot afford the Hyundai Sonata because of this problem. It can increase the fuel economy, and you have to refill your car after every short road trip.
People cannot get the expected mileage after filling their vehicle’s gas tank. Moreover, it is disturbing because the resale value also decreases due to less gas economy.
The issue mainly occurs while driving at high speed, off-roading, and in hilly areas.
Spark plug issues
The oil also starts accumulating on the spark plug, making them faulty. However, it is a necessary component for the ignition purpose.
Its layer can disturb the functioning of spark plugs, and it cannot provide the proper electricity for the ignition of air and fuel mixture.
It also enters into the spark plug holes through tube seals and valves. As a result, it can cause complete damage to all of its components, and you have to replace the spark plug.
The oil ash deposit on this part is the best indicator that your engine consumes more fuel than under normal conditions.
The color of the smoke also changes due to more oil consumption. Therefore, you should check all the components after seeing blue smoke from the exhaust system.
The blue smoke comes due to the entry of fuel into the exhaust system. You can see the blue smoke from the tailpipe of the exhaust system.
In addition, you can also feel the smell of the smoke while driving. The blue smoke also affects the performance of the engine and its parts.
They start to work less efficiently, and their durability also decreases. It is not the exact blue shade, but it seems to be a mixture of greyish and blue colors. You should stop your car and check the oil leakage.
Check engine light ON
The excessive burning from the engine also causes the check engine light to appear o the dashboard screen.
It is the safety system that alerts people about the damaging situation. You cannot ignore this light and check different components after stopping your car to find out the problem.
The check engine light appears on the screen to indicate that there is some problem with engine components that causes more fuel consumption.
The issue also comes due to wear and tear in engine parts. The engine also consumes more gas after becoming old and faulty.
