Oil-burning foresters: learn the common causes and solutions

The Subaru Forester is a popular SUV known for its reliability and off-road capabilities. However, one question that often arises is whether the Subaru Forester experiences excessive oil consumption. In this blog post, we will delve into the issue of “is subaru forester oil consumption” a myth or a reality.

What is Excessive Oil Consumption?

Excessive oil consumption refers to the situation where an engine burns or leaks an unusually high amount of oil, requiring frequent top-ups. This can result in reduced engine performance, increased emissions, and potential engine damage.

Is Subaru Forester Oil Consumption a Common Problem?

The answer to this question is not straightforward. While some Subaru Forester owners report experiencing excessive oil consumption, others have not encountered any such issues. The prevalence of oil consumption problems varies depending on the model year, engine type, and driving conditions.

Causes of Subaru Forester Oil Consumption

If your Subaru Forester is experiencing excessive oil consumption, several potential causes should be considered:

• Piston Rings: Worn or damaged piston rings can allow oil to seep into the combustion chamber, leading to burning.
• Valve Stem Seals: Leaky valve stem seals can cause oil to enter the cylinders when the engine is not running.
• Turbocharger: Turbocharged engines can consume more oil due to the increased pressure and heat.
• Oil Leaks: Leaks from the engine, oil pan, or gaskets can result in oil loss.

Symptoms of Subaru Forester Oil Consumption

If you suspect your Subaru Forester may be consuming excessive oil, look out for the following symptoms:

• Low Oil Level Indicator: The vehicle’s oil level indicator will illuminate when the oil level drops below a certain point.
• Frequent Oil Top-Ups: You may need to add oil to your engine more often than usual.
• Blue Smoke from Exhaust: Burning oil can produce a bluish smoke from the exhaust.
• Reduced Engine Performance: Excessive oil consumption can lead to decreased engine power and acceleration.

Diagnosing Subaru Forester Oil Consumption

To diagnose oil consumption issues, a mechanic will typically perform the following steps:

• Visual Inspection: The engine and surrounding areas will be inspected for any leaks or damage.
• Oil Consumption Test: The mechanic will monitor the oil level over a specific distance or time frame to determine the rate of consumption.
• Compression Test: This test measures the compression in each cylinder to identify any potential piston ring issues.

Solutions to Subaru Forester Oil Consumption

The solution to excessive oil consumption depends on the underlying cause. Common remedies include:

• Replacing Piston Rings: Worn piston rings may need to be replaced to prevent oil from entering the combustion chamber.
• Replacing Valve Stem Seals: Leaky valve stem seals can be replaced to stop oil from leaking into the cylinders.
• Repairing Oil Leaks: Any leaks in the engine, oil pan, or gaskets should be repaired to prevent oil loss.
• Using High-Mileage Oil: Oils specifically formulated for high-mileage engines can help reduce oil consumption.

Preventing Subaru Forester Oil Consumption

To prevent excessive oil consumption in your Subaru Forester, follow these tips:

• Regular Oil Changes: Stick to the manufacturer’s recommended oil change intervals to keep your engine clean and lubricated.
• Use High-Quality Oil: Choose high-quality synthetic or semi-synthetic oil that meets the manufacturer’s specifications.
• Avoid Aggressive Driving: Hard acceleration and braking can put additional stress on the engine and increase oil consumption.
• Monitor Oil Level Regularly: Check your oil level regularly using the dipstick to ensure it is within the acceptable range.

Final Note: Is Subaru Forester Oil Consumption a Myth or a Reality?

While excessive oil consumption is not a universal problem for the Subaru Forester, it is a possibility that owners should be aware of. By understanding the potential causes, symptoms, and solutions, you can proactively address any oil consumption issues and ensure the longevity of your vehicle.
