How long does 0w20 synthetic oil last Subaru?

The recommended oil change interval for 0w20 synthetic oil in a Subaru vehicle is typically around 6,000 to 7,500 miles, or 6-12 months, depending on your driving conditions and habits. However, the exact oil change interval can vary based on several factors.


Understanding 0w20 Synthetic Oil in Subarus


Subaru recommends the use of 0w20 synthetic oil in many of their newer models, as it helps improve fuel efficiency and engine performance. Synthetic oils are designed to last longer than conventional oils, with superior resistance to breakdown and better protection for your engine.


The "0w20" designation refers to the oil's viscosity, which determines how easily it flows. The "0w" means the oil has a very low viscosity when the engine is cold, allowing for easier cold starts, while the "20" indicates the oil's viscosity at normal operating temperatures.


Factors Affecting Oil Change Interval


Several factors can influence the recommended oil change interval for your Subaru, including:



  • Driving Conditions: If you frequently drive in extreme temperatures, tow heavy loads, or engage in high-performance driving, you may need to change your oil more frequently.

  • Driving Habits: Aggressive acceleration, frequent idling, and stop-and-go traffic can all contribute to faster oil degradation, requiring more frequent changes.

  • Oil Quality: Using a high-quality, name-brand 0w20 synthetic oil can help extend the oil change interval compared to lower-quality alternatives.

  • Vehicle Age and Mileage: Older Subaru models or those with higher mileage may require more frequent oil changes to ensure optimal engine protection.


It's important to consult your Subaru's owner's manual or speak with a qualified mechanic to determine the best oil change interval for your specific vehicle and driving conditions.


Maintaining Your Subaru's Engine


Regular oil changes are just one aspect of maintaining your Subaru's engine health. Other important maintenance tasks include:



  • Checking and replacing air filters as needed

  • Inspecting and replacing spark plugs at the recommended intervals

  • Monitoring and addressing any warning lights or engine performance issues

  • Keeping up with other scheduled maintenance, such as fluid flushes and tire rotations


By following the recommended maintenance schedule and using high-quality 0w20 synthetic oil, you can help ensure your Subaru's engine runs smoothly and efficiently for years to come.

Why do subarus need so many oil changes?


Over time, oil breaks down and becomes contaminated with dust, debris, and sludgy deposits. If you don't get your oil changed regularly, this dirty oil can cause increased friction and engine damage. Subaru recommends getting your oil changed every 6 months or 6,000 miles, whichever comes first.



Does full synthetic oil really last 10000 miles?
