About Oil Consumption

High oil consumption repairs Hamilton

Correct oil levels are vital to the health and longevity of your car’s engine. Oil lubricates the various parts inside your engine, preventing them from creating friction. When oil burns, leaks or loses its effectiveness, engine parts may begin to rub against each other and cause increased wear on the engine. For this reason, it is highly recommended that you regularly check your car’s engine oil levels using the dipstick.

High oil consumption occurs when oil is leaving your engine at an increased rate. This can mean that you will need to refill your engine more often. It can also result in permanent engine damage occurring if the problem is left unnoticed.


Causes of excessive oil consumption:

Excessive oil consumption in a vehicle can be concerning and may indicate an underlying issue. Here are some common causes of excessive oil consumption:

  • Worn Piston Rings: Piston rings are responsible for sealing the combustion chamber and preventing oil from entering the combustion process. If the piston rings wear out or become damaged, they can allow oil to pass into the combustion chamber, leading to increased oil consumption.
  • Valve Seal or Guide Wear: The valve seals and guides are responsible for controlling the flow of oil into the cylinder head. If these components wear out or become damaged, they can allow oil to enter the combustion chamber and be burned along with the fuel mixture.
  • PCV System Issues: The Positive Crankcase Ventilation (PCV) system is designed to prevent the buildup of pressure and contaminants in the crankcase. If the PCV valve or other components of the system become clogged or malfunction, it can disrupt the proper circulation of gases, leading to increased oil consumption.
  • Oil Leaks: External oil leaks, such as from a faulty gasket, seal, or oil pan, can result in oil loss and excessive consumption. Leaks allow oil to escape from the engine, reducing the oil level and requiring frequent top-ups.
  • Improper Oil Viscosity: Using an incorrect or inappropriate viscosity of oil for the engine can affect its ability to properly lubricate the internal components. This can result in increased friction, heat, and oil consumption.
  • Engine Wear or Damage: If the engine has internal wear or damage, such as worn cylinder walls or a damaged valve train, it can affect the oil control within the engine. Oil can be consumed more rapidly due to increased internal clearance or oil flow issues.
  • Driving Habits: Aggressive driving, excessive idling, or sustained high-speed driving can increase oil consumption. These driving conditions put more stress on the engine, leading to higher oil consumption.

Symptoms of high oil consumption:

There are several common symptoms associated with high oil consumption. These include:

  • Low Oil Level: If you frequently find yourself needing to add oil between regular oil changes or notice that the oil level on the dipstick consistently drops below the recommended range, it may indicate high oil consumption.
  • Exhaust Smoke: Excessive oil consumption can result in noticeable exhaust smoke, particularly upon startup or during acceleration. Blue or gray smoke, often described as “burning oil” smoke, is a typical indication of oil being burned in the combustion chamber.
  • Dirty Spark Plugs: When oil enters the combustion chamber and gets burned, it can cause discoloration of the spark plugs. Dirty spark plugs may result in engine misfires, rough idling, or a decrease in engine performance.
  • Increased Emissions: Burning excessive oil can lead to increased emissions, as oil is not a clean-burning fuel. You may fail an emissions test or notice a strong odor from the exhaust indicating the presence of oil.
  • Engine Deposits: Excessive oil consumption can contribute to the buildup of carbon deposits inside the engine. These deposits can affect engine performance, fuel efficiency, and overall engine health.
  • Engine Overheating: Insufficient lubrication due to high oil consumption can lead to increased friction and heat within the engine. If the engine overheats frequently, it could be a result of inadequate oil supply and lubrication.
