Can I use conventional oil in my Subaru?
As a Subaru owner, you might be wondering whether conventional oil is suitable for your vehicle. With years of experience in car maintenance and repair, I’ve encountered this question frequently. Let’s dive into the details to help you make an informed decision about the type of oil to use in your Subaru.
Understanding Subaru's Oil Requirements
Subaru vehicles are known for their unique Boxer engines, which require specific care to maintain their performance and longevity. Most modern Subaru models, especially those manufactured in the last decade, are designed to run on synthetic oil. This is because synthetic oil provides better lubrication, withstands higher temperatures, and resists breakdown more effectively than conventional oil.
However, if your Subaru is an older model or has been running on conventional oil without issues, you might be able to continue using it. That said, it’s essential to consult your owner’s manual or speak with a trusted mechanic to confirm the manufacturer’s recommendations for your specific model and year.
Why Synthetic Oil Is Often Recommended
There are several reasons why synthetic oil is the preferred choice for most Subaru vehicles:
- Enhanced Engine Protection: Synthetic oil provides superior protection against wear and tear, especially in high-performance engines like Subaru’s Boxer engines.
- Better Performance in Extreme Temperatures: Synthetic oil flows more easily in cold weather and maintains its viscosity in high heat, ensuring optimal engine performance year-round.
- Longer Oil Change Intervals: Synthetic oil lasts longer than conventional oil, meaning fewer oil changes and lower maintenance costs over time.
When Conventional Oil Might Be Acceptable
While synthetic oil is generally recommended, there are scenarios where conventional oil might be acceptable:
- Older Subaru Models: If your Subaru was manufactured before synthetic oil became the standard, it might be compatible with conventional oil. Always check your owner’s manual for guidance.
- Temporary Use: In rare cases where synthetic oil is unavailable, conventional oil can be used temporarily. However, it’s crucial to switch back to synthetic oil as soon as possible.
Final Thoughts
In most cases, using synthetic oil in your Subaru is the best choice to ensure optimal performance and engine longevity. However, if you’re considering using conventional oil, consult your owner’s manual or a trusted mechanic to determine if it’s suitable for your specific vehicle.
