How often should I change my Subaru Legacy oil?

The recommended oil change interval for a Subaru Legacy is generally every 5,000 to 7,500 miles, or every 6 to 12 months, whichever comes first. However, the exact oil change schedule can vary depending on your driving conditions and the age of your vehicle.


Understanding Oil Change Recommendations for Subaru Legacy


Subaru recommends changing the oil in a Legacy every 5,000 to 7,500 miles or every 6 to 12 months, whichever comes first. This is a general guideline, but your specific oil change interval may need to be adjusted based on your driving habits and conditions.


Factors that can impact your oil change schedule include:



  • Driving in extreme temperatures (very hot or very cold)

  • Frequent towing or hauling heavy loads

  • Extensive idling or stop-and-go driving

  • Driving on dusty or muddy roads


If you regularly experience any of these conditions, you may need to change your oil more frequently, such as every 3,000 to 5,000 miles. Consult your owner's manual or speak with a Subaru service technician to determine the best oil change schedule for your specific driving needs.


Importance of Regular Oil Changes


Changing your Subaru Legacy's oil at the recommended intervals is crucial for maintaining the health and longevity of your vehicle's engine. Fresh oil helps to lubricate moving parts, reduce friction, and prevent the buildup of harmful deposits that can lead to engine damage over time.


Neglecting oil changes can result in a range of issues, including reduced fuel efficiency, decreased engine performance, and even complete engine failure in severe cases. By staying on top of your oil change schedule, you can help ensure your Subaru Legacy runs smoothly and reliably for years to come.


Tips for Effective Oil Changes



  • Use the oil type recommended by Subaru, which is typically a synthetic or synthetic blend oil.

  • Change the oil filter at the same time as the oil to ensure maximum engine protection.

  • Keep track of your mileage and oil change dates to stay on top of the recommended schedule.

  • Consider having your oil analyzed periodically to check for any potential issues with your engine.


By following Subaru's oil change recommendations and adjusting your schedule as needed, you can help maintain the health and performance of your Legacy's engine for the long haul.

How often should I change my synthetic oil on my Subaru?


The general rule for Subaru vehicles is to get an oil change every 6,000 miles and every six months, whichever comes first. With that said, don't go more than six months without getting an oil change, no matter how much or how little you drive.



How long can you go past your oil change on a Subaru?


If your daily driving primarily consists of mostly highway miles, with minimal stop-and-go traffic and no extreme conditions, you can usually follow Subaru's general recommendation to get the oil changed every 6,000 to 7,500 miles.



How often does a Subaru Legacy need an oil change?


For the most part, your Subaru needs an oil change every 5,000 to 7,000 miles. However, if you tend to travel under more extreme circumstances, you may want to consider having an oil replacement more frequently.



Will my Subaru tell me when it needs an oil change?


Don't forget that your Subaru also has indicator lights in the dash that will alert you when your oil system needs immediate attention.



Does a Subaru Legacy need synthetic oil?


If you drive a Subaru Legacy produced after 2013, your vehicle likely requires 0W-20 synthetic oil. Models produced from 2005-2010 use synthetic 5W-30. The type of engine under the hood can also affect the required type of oil. For example, a Legacy with a 6-cylinder engine might use 5W-30 instead of 0W-20.



Do all Subarus need synthetic oil?


Naturally aspirated engines in the newest Forester, Impreza, Legacy, Outback, and BRZ models as well as turbocharged models require Subaru Synthetic Motor Oil (or its equivalent).



Can I put 5W-30 instead of 0W20 on my Subaru Outback?


Like the Crosstrek, the oil for the Subaru Outback needs to be an API classification SN or ILSAC GF-5. Also like the Crosstrek, the Outback engine should be filled with 0W-20 synthetic oil. If synthetic oil isn't available, you can use either 5W-30 or 5W-40 conventional oil.



Will it hurt to run 0w20 instead of 5w30?


Can I use a 0W-20 in my car that recommends 5W-30? No, if your owner's manual calls for a thicker oil, you should not use a thinner SAE grade nor use a thicker oil for a recommended thinner oil vis-grade. Using the proper viscosity motor oil will help protect and maintain the performance of your vehicle's engine.



What oil brand does Subaru recommend?


Some prevalent oil brands that meet Subaru's standards include Mobil 1, Castrol, and Pennzoil. These brands produce high-quality synthetic oils specifically formulated for Subaru engines.
