Top 5 Tips to Keep Your Subaru Engine Safe from Ringland Failure

Running your Subaru engine too hard or not giving it proper maintenance can lead to ringland failure, a common issue faced by Subaru owners. Ringland failure occurs when the piston rings break off, causing the engine to lose compression and eventually fail. 

However, there are ways to prevent this from happening. Here are the top five tips to keep your Subaru engine safe from ringland failure.

Tip 1: Use High-Quality Oil

High-quality oil is crucial in keeping your Subaru engine safe from ringland failure. The oil lubricates the engine and helps prevent metal-on-metal contact, reducing the risk of ringland failure.

Additionally, high-quality oil has additives that help protect the engine from wear and tear. Always use oil that meets your Subaru's specifications and change it at the recommended intervals.

Tip 2: Keep Your Engine Cool

Overheating is one of the main causes of ringland failure. To prevent this from happening, make sure your engine stays cool. Check your coolant levels regularly and replace them when necessary.

You should also inspect your radiator and cooling fans to ensure they are working correctly. If your engine starts to overheat, pull over and let it cool down before continuing your journey.

Tip 3: Avoid Heavy Loads

Carrying heavy loads, such as towing a trailer or carrying heavy equipment, can strain your engine, increasing the risk of ringland failure. Avoid carrying heavy loads if possible, or limit the weight as much as possible. 

If you must carry a heavy load, make sure your vehicle is equipped to handle it and take breaks to allow your engine to cool down.

Tip 4: Use High-Octane Fuel

Using high-octane fuel can help prevent ringland failure in your Subaru engine. High-octane fuel has a higher resistance to detonation, which can cause piston rings to break off.

Additionally, high-octane fuel can help prevent pre-ignition, which can also cause ringland failure. Check your owner's manual to see what octane rating your Subaru requires, and always use fuel that meets or exceeds that rating.

Tip 5: Perform Regular Maintenance

Regular maintenance is crucial in keeping your Subaru engine safe from ringland failure. Follow the manufacturer's recommended maintenance schedule and have your engine inspected by a professional mechanic regularly.

Your mechanic can check for signs of wear and tear and make any necessary repairs before they lead to more significant issues. Regular maintenance can also help you catch any issues early on, preventing them from causing ringland failure.

Final Thoughts

Ringland failure can be a costly and frustrating issue for Subaru owners. However, by following these top five tips, you can help prevent ringland failure and keep your engine running smoothly.

Always use high-quality oil, keep your engine cool, avoid heavy loads, use high-octane fuel, and perform regular maintenance. This can help keep your Subaru engine safe and reliable for years to come.
