Can I use Mobil 1 oil in my Subaru?

Yes. Mobil 1 synthetic motor oil can be used in most Subaru engines as long as you choose the correct viscosity and confirm the oil meets Subaru’s required specifications as stated in your owner’s manual.

Understanding Subaru’s oil requirements

Subaru vehicles rely on specific oil viscosity and performance standards to protect engine longevity and maintain fuel efficiency. The most important factors are the recommended viscosity for your model year and ensuring the oil meets the API and ILSAC specifications listed in the owner's manual. While Mobil 1 offers oils that meet these standards, you must verify the exact product label to ensure compatibility with your Subaru.

Viscosity and specifications to match

Check your owner's manual for the recommended viscosity (for many modern Subarus this is 0W-20, while some older or certain climates may call for 5W-30). Then look for an oil that lists API SN (or better) and ILSAC GF-5 (or newer) on the bottle. If the Mobil 1 product you choose shows those specs for the correct viscosity, it is generally suitable for a Subaru when used as directed.

Mobil 1 products commonly used in Subaru engines

Before selecting a product, ensure the oil’s viscosity matches your model’s specification and that the bottle lists the appropriate API/ILSAC coverage. The following Mobil 1 oils are commonly considered compatible with Subaru engines when they meet the required viscosity and specifications:

• Mobil 1 0W-20 synthetic motor oil — widely used in many Subaru models that call for 0W-20, typically listed as API SN/ILSAC GF-5 on the label.


• Mobil 1 5W-30 synthetic motor oil — suitable for Subaru models that specify 5W-30 (less common in newer models, more common in older ones or specific climates), with API SN/ILSAC GF-5 on the label.


• Mobil 1 High Mileage 0W-20 or 5W-30 — designed for higher-mileage Subarus, provided the viscosity matches the manual and the oil lists API SN/ILSAC GF-5.


• Mobil 1 ESP Formula 0W-30 or 5W-30 — available in certain regions; compatibility depends on matching the required viscosity and Subaru specs on the bottle.

Concluding note: These Mobil 1 options are broadly compatible with Subaru engines when they match the model’s required viscosity and Subaru’s specifications. Always verify the exact specs on the product label or the Mobil 1 technical data sheet for your chosen viscosity.

Practical steps to use Mobil 1 in a Subaru

To confidently switch or confirm Mobil 1 for your Subaru, follow these steps:

1. Consult your owner’s manual to determine the recommended viscosity for your model year and climate.


2. Check the oil bottle to confirm the product lists API SN (or better) and ILSAC GF-5 (or newer) for the specified viscosity.


3. Choose a Mobil 1 product that matches the exact viscosity and listed specs for your vehicle.


4. Ensure you use the correct oil capacity and change interval recommended by Subaru, and replace the oil filter with a compatible model.


5. Keep receipts or service records in case you need to reference the oil specification for warranty or service history.

Bottom line: Using Mobil 1 in a Subaru is generally fine when the oil meets the manufacturer’s viscosity and spec requirements. Always cross-check the bottle label and your manual before changing oil type or viscosity.

Turbocharged and specialty considerations

Subaru turbocharged engines (for example, some WRX/STI models) often have more stringent oil requirements and may favor specific viscosities (such as 5W-30 or 5W-40 in certain climates or model years). In these cases, confirm the exact viscosity and spec from the manual and ensure the Mobil 1 product you select is certified for that specification. If in doubt, contact Subaru customer service or Mobil 1 technical support for guidance.

Summary

For most Subaru owners, Mobil 1 is a viable option as long as you pick the correct viscosity (commonly 0W-20 for modern models) and verify that the oil carries API SN/ILSAC GF-5 or newer on the label. Always follow the model-specific guidance in your owner’s manual, and confirm the product’s specifications before purchasing. A careful match will help maintain engine performance and warranty compliance.

What is the best oil to use for a Subaru?

The best oil for a Subaru depends on the engine type, but most modern non-turbo models require 0W-20 full synthetic oil, while turbo models require 5W-30 full synthetic oil. Always check your owner's manual for the exact specifications for your specific vehicle. Using the recommended full synthetic oil is crucial for optimal performance, protection, and fuel efficiency in newer Subaru engines. 
Oil types by engine

• Non-turbocharged engines: Use 0W-20 full synthetic oil. This is the factory-recommended oil for most recent Subaru models and is designed to work with the engine's low-friction design for optimal fuel economy. 
• Turbocharged engines: Use 5W-30 full synthetic oil. This is required for turbocharged Subaru engines from 2011 onwards and is also a suitable option for older models. 

Important considerations

• Always check the owner's manual: The owner's manual is the definitive source for your vehicle's oil requirements. 
• Full synthetic is best: Newer Subaru engines are designed for full synthetic oil, which offers better protection and longevity compared to conventional oil. 
• Viscosity matters: Using the wrong viscosity can lead to increased engine wear, reduced fuel efficiency, and potential engine damage. 
• Oil change schedule: Adhere to the recommended oil change interval in your manual, which is often every 6,000 miles for normal driving conditions. 
• Using conventional oil temporarily: If synthetic is unavailable, you can use 5W-30 conventional oil as a temporary substitute, but you should switch back to the correct synthetic oil at the next oil change. 

Why does Subaru recommend 0W20?

Subaru uses 0W−200 cap W minus 200𝑊−20 oil in its non-turbocharged engines because its low viscosity improves fuel economy and reduces friction, while also providing excellent protection across a wide range of temperatures. This specific oil is formulated to work with the low-friction design of these engines and is optimized to help them operate efficiently and last longer. 

• Improved fuel efficiency: The thinner viscosity of 0W−200 cap W minus 200𝑊−20 oil allows it to flow more easily, reducing drag and leading to a slight improvement in miles per gallon. 
• Enhanced cold-weather performance: It flows more readily in cold conditions than higher-weight oils, which helps with faster lubrication and less wear when the engine is starting up. 
• Optimized for engine design: Subaru formulates its 0W−200 cap W minus 200𝑊−20 oil specifically for its non-turbocharged engines to work well with their low-friction design and ensure optimal performance and longevity. 
• Consistent viscosity: Synthetic 0W−200 cap W minus 200𝑊−20 oil is designed to maintain its viscosity across both hot and cold weather extremes, preventing breakdown and providing consistent protection. 

What does Subaru recommend for an oil change?

Subaru's recommended oil change interval is every 6,000 miles or six months, whichever comes first, but this can vary based on driving conditions and your specific model. For harsh conditions like frequent short trips, heavy towing, or stop-and-go traffic, you may need more frequent changes (every 3,000-5,000 miles). Always consult your owner's manual for the most accurate information for your vehicle.
 
Standard recommendation

• 6,000 miles or six months, whichever comes first. 

Adjustments for driving conditions

• Change more frequently (3,000-5,000 miles) if your driving involves: 
  • Frequent short trips (under five miles) 
  • Stop-and-go traffic 
  • Driving in extreme temperatures 
  • Off-roading, commercial use, or racing 
  • Heavy towing 
• Consider changing more frequently for peace of mind: Many drivers choose an easier-to-track interval like 5,000 miles, which is still early enough to protect the engine. 

Important considerations

• Check your owner's manual: This is the most definitive source for your specific vehicle's needs, especially for oil type and viscosity. 
• Synthetic oil: Newer models often require synthetic oil, which can have longer intervals than conventional oil. 
• Change the filter: Always replace the oil filter when you change the oil. 
• Don't wait: Even if you don't drive often, oil breaks down over time. Have it changed at least once every six months.
