What type of oil for Subaru Crosstrek?
The Crosstrek typically requires synthetic 0W-20 engine oil.
In this article, we explain the standard oil specification for most Crosstrek models, note any year-by-year variations, and offer practical guidance on maintenance, brand choices, and climate considerations to keep your engine running smoothly.
Recommended oil type and specifications
The key details you need to know when buying oil for a Crosstrek are the viscosity, the oil type, and the certifications it must meet. Below is a concise guide to those requirements.
- Viscosity: 0W-20
- Oil type: Full synthetic engine oil
- Certifications: API SN or newer, ILSAC GF-5 or newer
- Brand guidance: Use a reputable brand that meets the above specs (Subaru Genuine Motor Oil 0W-20 is commonly recommended, or any major brand offering 0W-20 full synthetic that meets API SN/ILSAC GF-5)
Using the correct oil with the right viscosity and certifications helps optimize cold-start protection, fuel efficiency, and overall engine longevity. If you’re unsure about availability in your region, consult your owner's manual or a Subaru service professional for the exact specification for your model year.
Oil capacity and change interval
The Crosstrek’s engine oil capacity (including filter) is roughly four to five quarts, depending on the exact year and engine variant. Always confirm the capacity for your specific model year in the owner’s manual or by asking a Subaru dealer.
- Use the recommended 0W-20 synthetic oil that meets API SN or newer and ILSAC GF-5 or newer.
- Ensure you replace the oil filter at every oil change.
- Follow the maintenance interval advised by Subaru or the vehicle’s Oil Life Monitor; many Crosstrek models use a monitor to indicate when an oil change is needed, rather than a fixed mile-based schedule.
- Check the oil level regularly (monthly or before long trips) using the dipstick and top up if needed with the same specification oil.
In practice, most Crosstrek owners perform oil changes when the vehicle’s monitoring system indicates it or at the interval specified in the manual. If you drive in severe conditions (extremely hot or cold climates, frequent short trips, or heavy towing), consult the manual or a technician for any recommended adjustments to the interval or oil spec.
Choosing a brand and where to buy
When selecting an oil brand, you have several reliable options that meet the Crosstrek’s spec. Consider the following guidance to ensure compatibility and performance.
- Subaru Genuine Motor Oil 0W-20 (fully synthetic) for guaranteed compatibility
- Major brands offering 0W-20 full synthetic that meet API SN or newer and ILSAC GF-5 or newer (examples include Mobil 1, Castrol, Pennzoil, Valvoline, and others)
- Always verify that the product label lists 0W-20, synthetic, and API SN or newer, GF-5 or newer on the container you purchase
Store shelves and service centers commonly stock 0W-20 synthetic oils that meet Subaru’s specifications, making it straightforward to find a suitable option. If you’re unsure, ask a parts adviser or your local Subaru service department for a validated choice for your exact model year.
Climates and driving conditions
Cold weather considerations
0W-20 provides better cold-start protection and quicker oil circulation in low temperatures, which helps with engine start-up in winter months. If you live in areas with severe cold, sticking to 0W-20 synthetic is typically advised to maximize reliability on cold starts.
Hot weather and demanding driving
In hotter climates or when the Crosstrek is used for frequent longer trips, the same 0W-20 synthetic oil continues to perform well, maintaining proper viscosity and protection. If you regularly tow or operate the vehicle under sustained heavy load, consult the owner's manual or a Subaru technician for any climate-specific recommendations.
Summary
For most Subaru Crosstrek models, the recommended engine oil is synthetic 0W-20 that meets API SN or newer and ILSAC GF-5 or newer. Use a reputable brand, change the oil and filter at the interval indicated by your Oil Life Monitor or manual, and keep an eye on oil level during routine checks. If you have a specific year or regional model, verify the exact specification in the owner’s manual or with a Subaru dealer to ensure optimal performance and warranty compliance.
What oil is recommended for a Subaru Crosstrek?
SAE 0W-20 full synthetic oil
Answer: Subaru officially recommends SAE 0W-20 full synthetic oil for all Crosstrek models from 2018 through 2025, including both the 2.0L and 2.5L Boxer engines.
What type of oil for 2015 Subaru Crosstrek?
The recommended oil for a 2015 Subaru Crosstrek is 0W-20 full synthetic oil. A conventional 5W-30 oil can be used in a pinch, but it should be replaced with 0W-20 synthetic oil at the next oil change.
- Recommended oil: 0W-20 full synthetic
- Alternative oil: 5W-30 conventional oil (only for temporary use)
- Oil capacity: Approximately 4.7 quarts with an oil filter change
- Important note: Always check your owner's manual for the most accurate information for your specific vehicle.
What oil to use for a 2014 Subaru Crosstrek?
The recommended oil for a 2014 Subaru Crosstrek is 0W-20 full synthetic oil. This is the preferred choice for optimal engine performance and protection, and you should use a high-quality brand or genuine Subaru oil. If 0W-20 synthetic is unavailable, you can use 5W-30 conventional oil in the short term, but it must be replaced with 0W-20 synthetic at the next oil change.
Oil specifications
- Grade: 0W-20 synthetic oil
- Alternative: 5W-30 conventional oil (only for a single oil change if 0W-20 is not available)
- Capacity: Approximately 4.7 to 5.1 quarts, including filter. Always check the level after filling.
- Certification: Look for oil with an ILSAC GF-5 certification mark.
Key recommendations
- Always check your owner's manual: for the most accurate information for your specific vehicle.
- Use full synthetic oil: for the best engine longevity and performance.
- If you use a conventional oil temporarily, be sure to switch back to 0W-20 synthetic oil at your next service.
- Consider using high mileage oil: if your vehicle has over 75,000 miles to help with potential leaks and consumption.
- Always check the oil level: after adding oil to ensure it is at the correct amount.
Can I put 5W-30 instead of 0W20 on my Subaru Outback?
Oil Type & Capacity for Subaru Outback
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. However, as suggested above, the engine oil should be replaced with synthetic oil during the next change.
