Understanding and Addressing Mitsubishi Eclipse Cross Engine Oil Consumption Issues

The Mitsubishi Eclipse Cross is a stylish and versatile compact SUV that has won over many drivers with its sleek design and advanced features. However, some owners of the 2018 and 2019 models have reported a concerning 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 of this issue, its implications, and provide actionable tips to help you manage or prevent it.

What Is Excessive Engine Oil Consumption?

Excessive engine oil consumption occurs when your vehicle burns through oil at a faster rate than normal. While all engines consume some oil over time, the Mitsubishi Eclipse Cross has been reported to use oil at an unusually high rate in certain models. This can lead to low oil levels, which may trigger engine warning lights or, in severe cases, cause engine damage.

Common Causes of Oil Consumption in the Mitsubishi Eclipse Cross

Understanding the root causes of this issue is the first step toward addressing it. Here are the most common culprits:

1. Piston Ring Wear

Piston rings are critical components that seal the combustion chamber and prevent oil from entering. Over time, these rings can wear out, allowing oil to seep into the combustion chamber and burn off. This is one of the primary causes of excessive oil consumption in the Eclipse Cross.

2. Valve Seal Leaks

Valve seals are designed to keep oil from leaking into the combustion chamber. If these seals become worn or damaged, oil can leak past them, leading to increased oil consumption.

3. PCV Valve Malfunction

The Positive Crankcase Ventilation (PCV) valve regulates pressure within the engine’s crankcase. A malfunctioning PCV valve can cause excessive pressure, forcing oil past the piston rings and into the combustion chamber.

4. Oil Viscosity Issues

Using the wrong oil viscosity or low-quality oil can exacerbate oil consumption problems. The oil may not provide adequate lubrication or may break down more quickly, leading to increased consumption.

How Oil Consumption Affects Your Vehicle

Excessive oil consumption isn’t just an inconvenience—it can have serious implications for your vehicle’s performance and longevity:

• Reduced Engine Performance: Low oil levels can lead to decreased power output, increased fuel consumption, and even engine misfires.
  
• Engine Longevity: Prolonged oil consumption can cause significant wear on engine components, potentially leading to costly repairs or even engine failure.
  
• Increased Maintenance Costs: Frequent oil top-ups, more frequent oil changes, and potential engine repairs can add up quickly.
  

What Can You Do to Prevent or Mitigate Oil Consumption?

While the issue may seem daunting, there are steps you can take to manage or even prevent excessive oil consumption in your Mitsubishi Eclipse Cross:

1. Stick to Regular Maintenance

Follow Mitsubishi’s recommended maintenance schedule, including regular oil changes. Use the correct oil viscosity as specified in your owner’s manual to ensure optimal engine performance.

2. Monitor Oil Levels Regularly

Make it a habit to check your oil levels at least once a month. If you notice that your oil levels are dropping faster than usual, it’s time to investigate further.

3. Get a Professional Inspection

If you suspect excessive oil consumption, take your vehicle to a qualified mechanic or Mitsubishi dealership. They can diagnose the issue and recommend appropriate repairs, such as replacing worn piston rings or valve seals.

4. Stay Updated on Software Fixes

In some cases, Mitsubishi has released software updates to address engine management issues that may contribute to oil consumption. Ensure your vehicle’s software is up to date by checking with your dealership.

5. Consider Extended Warranty or Recalls

If your vehicle is still under warranty, contact Mitsubishi to see if the oil consumption issue is covered. Some owners have successfully had repairs covered under warranty.

What Mitsubishi Owners Are Saying

Many Mitsubishi Eclipse Cross owners have expressed frustration with the oil consumption issue, particularly when it leads to frequent oil top-ups and unexpected maintenance costs. Some have also noted that the problem can be difficult to diagnose, as it may not always trigger warning lights or error codes.

While some dealerships have been proactive in addressing the issue, others have been slower to respond, leading to dissatisfaction among owners. If you’re experiencing this problem, it’s important to advocate for yourself and seek solutions from Mitsubishi or a trusted mechanic.

Final Thoughts

Excessive oil consumption in the Mitsubishi Eclipse Cross is a significant concern, particularly for owners of the 2018 and 2019 models. While the root causes can vary, common factors include piston ring wear, valve seal leaks, and PCV valve malfunctions. The long-term implications for engine performance and reliability are considerable, but with regular maintenance, proactive monitoring, and professional inspections, you can mitigate these risks.

If you’re experiencing this issue, don’t wait—take action to protect your vehicle and your investment. By staying informed and proactive, you can keep your Mitsubishi Eclipse Cross running smoothly for years to come.
