Does Subaru require synthetic oil?
Subaru vehicles are known for their reliability, performance, and unique engineering, particularly their Boxer engines and all-wheel-drive systems. However, when it comes to maintenance, one common question Subaru owners ask is whether their vehicles require synthetic oil. In this article, we’ll explore the answer to this question and provide insights into why synthetic oil might be the best choice for your Subaru.
Subaru's Recommendation for Oil Type
Subaru recommends synthetic oil for most of its modern vehicles, particularly those equipped with turbocharged engines or high-performance models. Synthetic oil is specifically designed to handle the demands of these engines, offering superior protection and performance compared to conventional oil. For naturally aspirated engines, Subaru may allow the use of conventional oil, but synthetic oil is still highly encouraged for optimal performance and longevity.
Why Synthetic Oil is Important for Subaru Engines
Subaru engines, especially the Boxer engines, have unique characteristics that make synthetic oil a better choice. Here are some reasons why:
- High-Temperature Resistance: Synthetic oil can withstand higher temperatures without breaking down, which is crucial for turbocharged engines that generate more heat.
- Better Lubrication: The design of Subaru's Boxer engine requires consistent and efficient lubrication to reduce wear and tear on engine components.
- Improved Engine Cleanliness: Synthetic oil contains fewer impurities and additives that help prevent sludge buildup, keeping the engine cleaner over time.
- Enhanced Cold-Weather Performance: Synthetic oil flows more easily in cold temperatures, ensuring proper lubrication during cold starts, which is especially important in colder climates.
Manufacturer's Warranty and Oil Requirements
Using the recommended oil type is essential to maintain your Subaru's warranty. If your owner's manual specifies synthetic oil, failing to use it could void your warranty in the event of engine damage. Always refer to your vehicle's manual for the specific oil grade and type required for your model.
How Often Should You Change Synthetic Oil in a Subaru?
Subaru typically recommends changing synthetic oil every 6,000 to 7,500 miles, depending on driving conditions and the specific model. However, if you frequently drive in extreme conditions, such as towing, off-roading, or stop-and-go traffic, you may need to change the oil more frequently. Regular oil changes are critical to maintaining engine health and performance.
Conclusion
While not all Subaru models strictly require synthetic oil, it is highly recommended for most modern vehicles, especially those with turbocharged engines. Synthetic oil provides superior protection, performance, and longevity for your engine, making it a worthwhile investment. Always consult your owner's manual or speak with a trusted mechanic to ensure you're using the right oil for your Subaru.

Frequently Asked Questions
How often should synthetic oil be changed on a Subaru?
every 7,500 to 10,000 miles
If your vehicle uses synthetic oil, it'll usually have to get changed every 7,500 to 10,000 miles.
What type of oil does Subaru recommend?
synthetic oil
Most new Subaru vehicles require synthetic oil with a viscosity rating of 0W-20.
How often do you change synthetic oil in a Subaru?
every 5,000 to 7,500 miles
Synthetic Blend Oil Changes
A synthetic blend oil change offers superior oil life compared to a conventional oil change. Synthetic blend oil changes typically split the difference and are needed every 5,000 to 7,500 miles.
Should I use synthetic oil in my Subaru?
Subaru of America inc. recommends using synthetic motor oil in all turbo charged engines. When using synthetic oil, you must use oil of the same classification, viscosity and grade shown in this Owner's Manual, and must follow the oil and filter changing intervals shown in the maintenance schedule.
Do I really need fully synthetic oil?
Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can't compete with the overall engine performance and protection provided by synthetics.
Can I use 5W-30 instead of 0W20 in a Subaru Forester?
If you drive a Subaru Forester with a non-turbo engine, it requires 0W-20. If you drive a model with a turbo engine, you'll need 5W-30.
When did Subaru start using synthetic oil?
2011
Starting in 2011 when Subaru changed from Rubber timing belts to timing chains in the 4 cylinder motors, the factory switched to full synthetic motor oils, 0w/20. The chain driven 6 cylinder motor, still uses 5/30 syntec blend.
Does Subaru Forester use regular or synthetic oil?
What type of oil does a Subaru Forester take? The recommended Subaru Forester oil is best served by a 5W-30 synthetic motor oil, and thankfully, Subaru offers this as an OEM part that's got the Subaru blessing right on it. Want to learn more about the Subaru Forester oil change?
Can my car use regular oil instead of synthetic?
As for switching, you can freely switch back and forth from synthetic to semi-synthetic to conventional oil without any issues. I recently had Michael Thomas from Pennzoil on my radio show and talked about this very issue. You can find the Car Doctor podcast on johnfpaul.podbean.com or on most podcast sites.
Why do Subarus use so much oil?
Consumer Reports on Subaru Oil Consumption Issues
As a result, the new engine designs suffered restricted oil durability. Some consumer posts suggested that the piston ring design was the source of the problem. As a result, oil bypasses the piston and results in premature combustion.
