Should You Do A Subaru Engine Flush

Maintaining your Subaru’s engine is vital for ensuring its longevity and optimal performance. One of the maintenance tasks that may come up in your vehicle’s service history is the idea of performing an engine flush. But should you do a Subaru engine flush? The decision to flush your engine depends on a variety of factors, including the age of your vehicle, the condition of the engine, and whether you’ve noticed any issues with its performance. At Empire Subaru, we’ll walk you through the benefits, risks, and when it might be necessary to perform an engine flush.

1. What Is An Engine Flush?

An engine flush is a service that involves adding a cleaning solution to the engine’s oil system. This solution is designed to break down sludge, grime, and other impurities that accumulate inside the engine over time. After the solution has had time to circulate and clean the engine, the oil is drained and replaced with fresh oil. An engine flush helps ensure that your engine is running as efficiently as possible by removing contaminants that can cause engine wear.

2. Benefits of Engine Flushing

The primary benefit of an engine flush is the removal of built-up sludge, dirt, and debris inside the engine. Over time, oil can degrade, causing deposits to form within the engine, which may lead to blockages and decreased engine efficiency. An engine flush can:

• Improve oil circulation
• Reduce wear on engine components
• Improve fuel efficiency
• Prevent potential engine damage

If your Subaru is showing signs of sluggish performance, or if the oil appears thick and dark despite regular oil changes, an engine flush may help restore your engine's smooth operation.

3. When Should You Consider an Engine Flush?

An engine flush is not a routine maintenance task. It is generally recommended only in specific situations:

• If your Subaru has high mileage and you’ve never had an engine flush before.
• If you notice poor engine performance, such as sluggish acceleration or strange noises.
• If the oil appears dirty or sludgy, even after changing it.
• If you’ve recently purchased a used vehicle and are unsure of its maintenance history.

It’s always a good idea to consult with a trusted mechanic before proceeding with an engine flush, especially if you notice symptoms of engine trouble. At Empire Subaru, we offer expert guidance on whether an engine flush is the right choice for your vehicle.

4. Risks of Engine Flushing

While an engine flush can offer significant benefits, it’s not without its risks. If your Subaru’s engine is already in poor condition, an engine flush may cause more harm than good. For example, if the engine has extensive buildup, the cleaning process may dislodge debris that could cause blockages in other parts of the engine. Additionally, older engines with seals that have already started to degrade may not benefit from an engine flush, as the process could cause leaks.

It’s important to weigh the pros and cons of an engine flush and have a professional assess whether it’s the best course of action for your Subaru.

Ultimately, an engine flush can be a useful tool for maintaining the health of your Subaru’s engine, but it’s not something that should be done unnecessarily. Always consult with a professional mechanic to determine whether this service is right for your vehicle. At Empire Subaru, our team is ready to help you assess your Subaru’s needs and ensure that it continues to run smoothly for years to come.
