The 2007 Subaru 2.5-liter four-cylinder typically uses 5W-30 engine oil, and you’ll need about 4.5 quarts with a filter. Oils can be conventional, synthetic, or a synthetic blend, so long as they meet the engine’s certification requirements. Always verify the exact specification in the owner’s manual or on the under-hood sticker for your specific model.
Recommended oil type and viscosity
Below is a concise guide to the oil options commonly used in the 2007 2.5 engine. It helps you choose a compatible product when you shop for oil.
- 5W-30 full synthetic oil
- 5W-30 synthetic-blend (semi-synthetic) oil
- 5W-30 conventional oil that meets API SN/ILSAC GF-5 or newer standards
Across these options, the key requirement is the 5W-30 viscosity and compliance with current API/ILSAC specifications. Your choice between synthetic, synthetic-blend, or conventional should reflect your driving conditions, budget, and how often you want to change the oil. Always follow the interval guidance in the manual and adjust for severe driving conditions when applicable.
Oil capacity and change intervals
Knowing the correct oil quantity and replacement schedule helps keep the engine in good shape between services.
- Oil capacity (including the filter): approximately 4.5 quarts (around 4.3 liters)
- Change interval: typically 7,500 miles (12,000 km) with synthetic oil; 3,000–5,000 miles (5,000–8,000 km) with conventional oil, depending on driving conditions and climate
These guidelines are standard references; your manual may provide exact figures for your trim level and climate. If you use an oil life monitor (where equipped) or have severe driving habits, adjust accordingly.
Choosing brand and certifications
Look for oils that meet current API service standards (for example, API SN or newer) and ILSAC GF-5 or newer, and ensure the label indicates 5W-30. Subaru owners often prefer reputable brands or OEM-recommended oils. Using a quality oil that meets these specs helps protect the engine, especially in the cold starts and city driving common to many 2007-era Subarus.
Bottom line and practical tips
For a 2007 Subaru 2.5, stick with 5W-30 oil and a 4.5-quart total capacity with a new filter. Choose the oil type (conventional, synthetic, or synthetic blend) based on your needs, but always prioritize the correct viscosity and certification. Regular oil changes on schedule are essential to long-term engine reliability.
Summary
The 2007 Subaru 2.5 engine is designed to run on 5W-30 oil, with an oil capacity of about 4.5 quarts including the filter. You can select from conventional, synthetic, or synthetic-blend 5W-30 oils, as long as they meet API SN/ILSAC GF-5 standards. Adhere to the maintenance interval in your owner’s manual and adjust for driving conditions to keep the engine performing well.
