Why does my Toyota burn so much oil?
If your Toyota vehicle is consuming an unusually high amount of engine oil, there could be a few potential reasons behind this issue. In this article, we'll explore the common causes of excessive oil consumption in Toyota models and provide guidance on how to address the problem.
Potential Causes of Oil Burning in Toyotas
There are several factors that can contribute to a Toyota burning more oil than expected. Some of the most common causes include:
- Worn piston rings or cylinders: As the engine components wear over time, the piston rings may no longer seal properly, allowing oil to be burned during combustion.
- Leaking valve seals: Faulty valve seals can allow oil to enter the combustion chamber, leading to increased oil consumption.
- Sludge buildup: Excessive sludge and deposits in the engine can restrict oil flow and cause oil to be burned.
- High mileage: Older Toyota engines with higher mileage are more prone to oil consumption issues as the components naturally wear down over time.
- Incorrect oil viscosity: Using an oil with the wrong viscosity for your Toyota's engine can contribute to increased oil burning.
It's important to note that the severity of the oil consumption issue can vary depending on the specific Toyota model, engine, and driving conditions.
Addressing Excessive Oil Consumption in Toyotas
If you've noticed your Toyota burning more oil than usual, there are a few steps you can take to address the problem:
- Check the oil level regularly: Monitor the oil level and top it up as needed, following the manufacturer's recommended oil change intervals.
- Inspect for leaks: Carefully inspect the engine for any visible oil leaks, which could be contributing to the oil consumption.
- Consider an oil consumption test: Your Toyota dealer can perform an oil consumption test to accurately measure the rate of oil burning and help identify the underlying cause.
- Replace worn components: If the oil consumption is due to worn piston rings, valve seals, or other engine components, you may need to have these parts replaced by a qualified mechanic.
- Use the recommended oil type: Ensure you're using the correct oil viscosity and quality as specified in your Toyota's owner's manual.
By addressing the root cause of the oil consumption issue, you can help restore your Toyota's engine performance and reduce the frequency of oil top-ups.
Is it normal for Toyota to burn oil?
Toyota considers burning a quart of oil normal for a car over 125000 miles or somewhere around that. So burning a quart or more at 200000+ is normal.
How do you fix a car that burns oil?
The fix for an engine that is burning oil is usually to hone the cylinder and put in a new set of rings sized to the new dimension. Sometimes switching to a higher viscosity oil or using an additive with the oil can reduce the oil consumption.
Why is my car losing oil but no leak or smoke?
When a car begins to lose oil but doesn't display any visible leaks, there could be several culprits at play. Common reasons include worn piston rings, a damaged head gasket, or an accumulation of oil in the engine's air-filtration system.
Is it bad to drive a car that burns oil?
The more oil your engine has burned, the greater the damage will be. The oil can ruin several critical components, including spark plugs and catalytic converters — it can even destroy the engine entirely.
What is the Toyota oil burning lawsuit?
Most car owners in Toyota class-action lawsuit for oil consumption claimed that the engines produced excess amounts of fuel when the car needed fuel at a relatively low rate. Then, they burned up completely when the car needed more fuel. As a result, the increase in oil consumption was harmful to the environment.

Which Toyota engines have excessive oil consumption?
Toyota finally took note of the problem in 2011, and a Technical Service Bulletin (TSB) was issued to acknowledge the oil consumption concerns in the following vehicles equipped with the affected 4-cylinder 2AZ-FE engine: 2007 – 2011 Toyota Camry. 2007 – 2011 Toyota Camry Hybrid. 2009 Toyota Matrix.
Why am I losing oil but no leaks?
When a car begins to lose oil but doesn't display any visible leaks, there could be several culprits at play. Common reasons include worn piston rings, a damaged head gasket, or an accumulation of oil in the engine's air-filtration system.
How do you stop engine oil consumption?
If you find that your car is burning through oil faster than normal, there are a few things you can do to help mitigate the problem.
- Check for leaks regularly.
- Use the correct oil grade.
- Follow the recommended oil change interval.
- Avoid excessive idling.
- Drive responsibly.
What year did Toyota fix the oil consumption problem?
The fix from Toyota, which came late in 2002, was a re-design of the heads plus a change in the PCV valve. The head design changed the oil return galleries and reshaped the baffles mounted to the underside of the valve covers.
