The most frequent causes of burning oil are harmed PCV valves, piston rings, or valve seals. Low oil levels in the engine, leaking hoses, a worn-out oil filter housing gasket, worn-out sealing surfaces, a loose or coming-out drain plug, and worn-out oil filter housing gaskets are a few causes of this.
The kind of oil you use might affect how much oil your engine burns. For instance, using synthetic oil and changing it too frequently can leave residual deposits on the cylinder walls, narrowing the space between them. Because they are unable to form a tight seal, this causes the hoses to leak and causes your Kia to burn oil.

Is oil burning on a Kia Soul typical?
I follow my father’s advice and check the oil in my car once a week. The Soul’s engine consumes oil, I’ve seen. I have to add three quarts of oil around every six months or 5,000 miles.
After checking it, the dealer confirms everything is in order. They seem to be saying, “Little Lady,” everything is fine and they want me to leave.
A: Oil is burnt during regular combustion, however different engines use oil differently.
According to Kia’s extremely detailed oil consumption studies, one quart of oil used per 1,000 miles or more is considered to be normal. The engine is working up to specification based on Kia’s standards for oil usage.
Why doesn’t my automobile leak oil yet is burning it?
Oil leakage into the combustion chamber is typically the result of one or more deteriorated components. Even minor wear on more recent engines running low-viscosity oil, like 5W-20, might result in oil entering this chamber. Several of the typical reasons for excessive oil usage are listed below:
Worn Out PCV Valve
Positive crankcase ventilation (PCV) is a crucial part of an engine that removes dangerous gases produced during combustion. This is accomplished by returning any extra gases to the combustion chamber where they are burned again before being expelled along with the exhaust.
However, a clogged PCV system might result in considerable oil blowback. Oil ends up being drawn into the engine through the air intake rather than being removed along with combustion gases. Most of the time, changing the PCV valve is all that is needed to fix this problem.
Worn Out Piston Rings or Cylinder Walls
Repairs can become expensive at this point. In order to maintain engine compression and stop combustion gases from escaping, each set of piston rings creates a seal against the cylinder walls. The seal, however, might no longer work correctly if your piston rings have worn out or the cylinder wall has started to disintegrate. A bad seal might allow oil to burn in the combustion chamber, leaving you with less oil than you had before.
Worn Out Valve Seal
Low oil levels can also result from defective valve stem seals. While valve stem seals are intended to control the amount of oil used and the lubrication of the valves, a cracked one has the exact opposite effect. A worn-out or cracked valve seal could allow oil to flow into the engine’s cylinders and eventually into the combustion chamber.
Why is my automobile burning oil all of a sudden?
Parts that are worn out frequently burn oil. Your car may burn oil as a result of worn piston rings or valve seals, for instance. Piston rings and valve seals both contribute to preventing engine oil from entering the combustion chamber.

Kia Recall Contact Information
Instructions on how and when to bring their Kia into a dealership should be sent to the owners of these vehicles by first class mail at the address on file. On March 21, 2022, letters are anticipated to be mailed. Call 1-800-333-4542 to reach Kia customer support. SC226 is the Kia recall number.
The ACU will be examined by dealers. A dealer will swap out the Airbag Control Unit for a “better” one if the airbag warning light is already on. If the light is not on, a software update will be applied that, according to Kia, will guarantee proper airbag deployment in the case of a collision.
Recall Reimbursement and Unaffected Cars
Kia asserts Sedonas produced in 2019 after January 10 come standard with an upgraded airbag control unit. Kia Fortes for the 2019 model year and new-generation Kia Souls for the 2020 model year both received a different component. According to the Defect Notice Report on the NHTSA website, “Kia will reimburse owners for repair charges previously paid pursuant to Kia’s General Reimbursement Plan submitted May 11, 2020.”
According to Kia and NHTSA, there have been no crashes that have been associated with problems with the airbag systems on the impacted Kia models to far. However, 947 warranty claims and 13 customer complaints have been made in relation to the flaw.
Air bags: Frontal
Some 2014 Soul vehicles are being recalled by Kia Motors America (Kia). If the Air Bag Control Unit (ACU) cannot communicate with the front impact sensors during a collision, the front air bags may not deploy.
Incorrect front air bag deployment might make it more likely that a crash will result in injuries.
The ACU software will be updated at no cost by the dealers. On April 4, 2022, owner notification letters were sent out. Call 1-800-333-4542 to reach Kia customer support. The recall number for Kia is SC229
Air bags
Certain 2017-2019 Sedona, Soul, Soul EV, 2017-2018 Forte, and 2017 Forte Koup vehicles are being recalled by Kia Motors America (Kia). The printed circuit board’s memory chip may come into touch with the Air Bag Control Unit (ACU) cover, breaking the electrical circuit. Air bags that are deactivated and won’t deploy in a collision could be caused by circuit damage.
Injury risk in a crash might increase if air bags do not deploy as intended.
Dealers will examine the ACU and, if necessary, replace it or update its software. There will be no fees for the repairs. On March 21, 2022, owner notification letters were sent out. Call 1-800-333-4542 to reach Kia customer support. SC226 is the Kia recall number.

A damaged engine could stall, making collisions more likely. Additionally, oil leaks onto hot exhaust components raise the possibility of a fire.
Owners will be informed by Kia, and dealers will evaluate the engine free of charge and replace it if necessary. Kia will also implement the Piston Ring Noise Sensing System (PNSS) application. On June 11th, 2021, the recall started. Call 1-800-333-4542 to reach Kia customer support. The recall number for Kia is SC209.
What symptoms indicate worn piston rings?
Drivers may be able to identify worn piston rings by their high oil consumption, white or gray exhaust smoke, poor acceleration, general loss of power, or poor engine performance. These metal rings in the form of hoops fit around each piston’s perimeter, creating a seal between the piston and the cylinder wall that enables the piston to absorb all of the energy from the expanding gases produced by the engine.
Because piston rings deteriorate with time, it’s critical to alert the car technician to the first indications of worn or damaged rings. The technician can identify the existence of a leak and the requirement for repair by performing a compression test. Engine oil is consumed in the combustion chamber due to worn piston rings, which limits the amount available.
TIP: Normally speaking, bluish grey smoke is typically produced when oil is burning, however black smoke generally denotes excessive fuel usage.

How long can an oil-burning car be driven?
James Dunst, a master mechanic at Bell Performance, frequently answers inquiries from the general public about lubricating oil. What type is better, how frequently should it be changed, and similar questions. Oil consumption is one issue that appears to be on their minds. How much is too much, and when should it be of concern?
James Dunst offers a mechanic’s perspective on the subject of your vehicle’s regular vs. abnormal oil usage today.
The majority of engines do, in fact, burn some oil. Most manufacturers deem one quart of oil to be sufficient for 1,500 miles or less. It should be noted that certain high-performance cars will use a quart of oil in less than 1,000 miles and are still regarded as appropriate.
There have been a few engine changes as a result of consumer desire for more fuel-efficient vehicles, which affects the solution to this problem. These modifications have an impact on how much oil an engine can burn while still being regarded acceptable.
To improve fuel efficiency, adjustments were made to the piston ringers. The point where the piston rings come into touch with the cylinder walls creates the most friction in an engine. The more oil the rings can scrape off the cylinder walls during the piston’s downward stroke, the higher the ring tension, the better. The piston ring tension has been decreased by the auto industry to reduce friction and increase fuel efficiency. Small amounts of oil have been burnt as a result of the change in ring tension that allowed it to pass the piston rings. The majority of well maintained automobiles’ regular oil consumption is mostly caused by this.
The switch to lighter motor oil is a further modification that has had an impact on oil consumption. Lightweight oil grades like 0W-20 are being used in the market to reduce friction and better lubricate internal engine components in cold weather. This thinner oil has a propensity to enter the combustion chamber after passing through the piston rings. Oil has leaked through oil seals and gaskets because of the use of these lesser motor oils, which is unusual for heavier motor oil.
Standard motor vehicles should have the source of a quart of oil consumption per less than 1,000 miles investigated. Extremely high oil usage, such as one quart every 500 miles, can harm catalytic converters.
How can oil burn be identified?
It could be difficult to determine that your car is burning oil if it is a recent model. This is so that the catalytic converter can disguise the signs of burning oil in newer vehicles. You are unaware that your car may be burning oil.
The symptoms of burning oil, however, are quite obvious and simple to identify in older vehicles. They consist of;
The lighting of the oil check light is one of the most noticeable warning signals of oil burning in vehicles. Don’t disregard it when you see it, please.
Low coolant level: Oil on the ground indicates leaks. However, if the oil level is steadily dropping without any sign of physical leaking, it is a definite sign that the oil is burning within. Because of the excessive coolant use by your engine at this point, oil consumption rises noticeably.
Engine misfiring: Another obvious sign that a car is burning oil is engine misfiring. Low coolant is a common cause of it. The engine overheats and misfires when the coolant is low and unable to keep the engine cool.
Spark plugs are harmed when oil in them burns during engine operation. A defective set of spark plugs will show up as oil in the plugs.
Blue smoke coming from your exhaust pipe is a surefire sign that your car is burning oil, according to the color of the smoke. When you start the car, you typically see this smoke.
Burning oil odor: This is frequently noticed when oil escapes from the engine and falls on nearby parts. Most of the time, these parts are hot. So you smell burning oil when these leaks come into contact with a hot surface.
