Understanding and Addressing the Subaru BRZ Limited Engine Oil Consumption Issue

The Subaru BRZ Limited is a beloved sports car known for its agility, sleek design, and thrilling driving experience. However, some owners of models produced between 2013 and 2016 have reported a frustrating issue: excessive engine oil consumption. This problem can lead to reduced performance, increased maintenance costs, and even long-term engine damage if left unaddressed. In this blog post, we’ll break down the causes, implications, and solutions for this issue, providing actionable advice to help you keep your BRZ running smoothly.

What Is the Oil Consumption Issue?

Excessive oil consumption occurs when the engine burns or leaks oil at a rate higher than normal. For Subaru BRZ Limited owners, this often means needing to top up oil levels between scheduled maintenance intervals. While some oil consumption is expected in high-performance engines, the levels reported in these models are concerning and can lead to serious engine problems if not managed properly.

How Does It Affect Your Vehicle?

The oil consumption issue can have several negative impacts on your Subaru BRZ Limited:

1. Engine Damage: Low oil levels increase friction and heat, which can cause premature wear and tear on engine components.
   
2. Reduced Fuel Efficiency: Burning oil can negatively affect your car’s fuel economy, costing you more at the pump.
   
3. Higher Maintenance Costs: Frequent oil top-ups and potential engine repairs can add up over time.
   
4. Resale Value: Vehicles with known oil consumption issues may have a lower resale value, as buyers may be wary of potential problems.
   

What Causes Excessive Oil Consumption?

Several factors contribute to the oil consumption issue in the Subaru BRZ Limited:

1. Piston Ring Design Flaws: In some models, the piston rings may not seal properly, allowing oil to seep into the combustion chamber and burn off.
   
2. Valve Cover Gasket Leaks: Faulty gaskets can lead to oil leaks, reducing the overall oil level in the engine.
   
3. PCV System Issues: A malfunctioning Positive Crankcase Ventilation (PCV) system can allow oil vapors to escape into the intake system, increasing oil consumption.
   
4. Engine Wear and Tear: Aggressive driving or lack of regular maintenance can exacerbate oil consumption over time.
   

Which Models Are Affected?

The oil consumption issue is most commonly reported in 2013-2016 Subaru BRZ Limited models. If you own one of these vehicles, it’s important to monitor your oil levels closely and take proactive steps to address any issues.

What Can You Do to Prevent or Fix the Issue?

Here are some practical tips to help you manage or prevent excessive oil consumption in your Subaru BRZ Limited:

1. Check Oil Levels Regularly: Make it a habit to check your oil level at least once a month and top up as needed.
   
2. Use High-Quality Oil: Synthetic oils with higher viscosity can help reduce oil consumption and provide better engine protection.
   
3. Address Faulty Components: If you suspect issues with your piston rings, valve cover gaskets, or PCV system, have them inspected and repaired by a professional.
   
4. Update Your ECU: Ensure your vehicle’s Engine Control Unit (ECU) is running the latest software, as updates may improve oil management.
   
5. Leverage Warranty Programs: Check if your vehicle is covered under any extended warranty programs related to oil consumption issues.
   

What Has Subaru Done About It?

Subaru has acknowledged the oil consumption issue in some of its models, including the BRZ. While no widespread recall has been issued, the company has addressed individual cases under warranty. If you’re experiencing this issue, contact your local dealership for diagnostics and potential repairs.
