2014 Subaru Forester: What Oil Should You Use?

Choosing the correct oil type for your 2014 Subaru Forester is crucial for maintaining its performance and longevity. This guide provides clear, actionable information to help you make the best choice, ensuring your engine runs smoothly for years to come. We’ll cover the recommended oil viscosity, specifications, and important considerations for your specific model.

Understanding Oil Viscosity for Your 2014 Forester

Oil viscosity refers to its thickness and resistance to flow. Subaru, like most manufacturers, specifies a particular viscosity grade recommended for optimal engine protection under various operating temperatures. For the 2014 Subaru Forester, the most commonly recommended oil viscosity grade is 0W-20. This synthetic oil offers excellent flow characteristics at cold temperatures, ensuring rapid lubrication upon startup, and maintains sufficient viscosity at higher operating temperatures to protect engine components.

Why 0W-20 is the Standard

The "0W" in 0W-20 indicates the oil's viscosity at cold temperatures (W stands for Winter). A lower number means the oil is thinner and flows more easily when the engine is cold. This is vital for preventing wear during the critical startup phase. The "20" indicates the oil's viscosity at operating temperature. Using the manufacturer-recommended viscosity ensures that the oil film provides adequate protection between moving parts.

Using Alternative Viscosities

While 0W-20 is the standard, some older service manuals or specific extreme conditions might suggest alternatives. However, it is strongly advised to stick with the 0W-20 synthetic oil as specified by Subaru for the 2014 model year. Using a different viscosity, especially one with a higher number like 5W-30 or 10W-40, could lead to reduced fuel efficiency, increased engine wear, and potentially affect warranty coverage. Always consult your owner's manual for the definitive recommendation for your vehicle.

Essential Oil Specifications and Certifications

Beyond viscosity, engine oil must meet specific performance standards and certifications. For your 2014 Subaru Forester, look for oils that meet or exceed the following:

• API Service Category: The American Petroleum Institute (API) sets performance standards for engine oils. For most 2014 gasoline engines, an oil meeting the API SN or a later category (like SP) is recommended. These categories ensure the oil provides enhanced protection against wear, deposits, and oxidation.
• ILSAC Certification: The International Lubricant Standardization and Approval Committee (ILSAC) also sets standards. Look for the ILSAC "starburst" symbol, which indicates the oil meets the latest fuel economy and emission system protection requirements. For 2014 models, this would typically be ILSAC GF-5 or a later standard.
• Synthetic vs. Conventional Oil: Subaru vehicles, especially those with boxer engines like the Forester, generally benefit from synthetic oil. Full synthetic 0W-20 oil offers superior protection, thermal stability, and longevity compared to conventional or synthetic blend oils. In our experience, using full synthetic consistently leads to better engine health over the long term.

Why Synthetic Oil is Preferred

Synthetic oils are chemically engineered to provide a more uniform molecular structure, resulting in better lubrication, reduced friction, and enhanced resistance to breakdown under extreme temperatures. This is particularly beneficial for Subaru's horizontally opposed (boxer) engines, which can generate significant heat.

Checking Your Oil Level and Condition

Regularly checking your oil level and condition is a vital part of vehicle maintenance. Low oil levels can lead to severe engine damage, while dirty or degraded oil can compromise lubrication and cooling.

How to Check Your Oil:

1. Park on a Level Surface: Ensure your vehicle is parked on a flat, level surface.
2. Warm Up the Engine: Run the engine for a few minutes to bring it up to operating temperature, then shut it off and wait 5-10 minutes for the oil to drain back into the oil pan.
3. Locate the Dipstick: Find the oil dipstick, usually marked with a brightly colored loop or handle (often yellow or orange).
4. Pull and Wipe: Pull the dipstick out completely and wipe it clean with a lint-free cloth or paper towel.
5. Reinsert and Remove: Fully reinsert the dipstick, then pull it out again.
6. Check the Level: Observe the oil level on the dipstick. There will be markings (usually "L" for low and "F" for full, or dots/crosshatchings) indicating the acceptable range. The oil level should be between these marks, ideally close to the "F" mark.
7. Inspect the Oil Condition: Note the oil's color and consistency. Healthy oil is typically amber or light brown. If it appears black, sludgy, or contains metal particles, it's time for an oil change.

Topping Up Oil

If the oil level is low, add the recommended 0W-20 synthetic oil one quart (or one liter) at a time, rechecking the dipstick after each addition until the level is within the acceptable range. Be careful not to overfill.

When to Change Your Oil

Subaru recommends an oil change interval based on mileage and time. For the 2014 Forester, refer to your owner's manual for the exact schedule, but a general guideline is:

• Every 5,000 to 7,500 miles (8,000 to 12,000 km) or every 6 months, whichever comes first, when using conventional oil.
• Every 7,500 to 10,000 miles (12,000 to 16,000 km) or every 12 months, whichever comes first, when using full synthetic oil (which is recommended).

Factors Affecting Oil Change Intervals

Driving conditions can influence how often you need to change your oil. If you frequently:

• Drive in dusty or dirty conditions
• Engage in extensive idling
• Make frequent short trips (especially in cold weather)
• Tow heavy loads

...you may need to change your oil more frequently, even when using synthetic oil. Following Subaru's "severe driving conditions" schedule is advisable in these cases. — Loch Sheldrake, NY Weather: Current Conditions & Forecast

Frequently Asked Questions (FAQs)

Q1: What is the oil capacity for a 2014 Subaru Forester?

A1: The 2014 Subaru Forester typically requires approximately 5.1 quarts (4.8 liters) of oil with a filter change. Always confirm this specification in your owner's manual, as it can vary slightly depending on the engine variant.

Q2: Can I use 5W-30 oil in my 2014 Subaru Forester?

A2: While your Forester might run on 5W-30, it is not the recommended viscosity by Subaru for optimal performance and protection. Sticking to the specified 0W-20 synthetic oil ensures the best fuel economy and engine longevity. Using a different oil viscosity may impact your warranty.

Q3: How often should I change the oil filter on my 2014 Forester?

A3: It is standard practice to replace the oil filter every time you change the engine oil. This ensures that the new oil is not contaminated by debris from the old filter and maintains optimal filtration performance.

Q4: What happens if I don't change my oil regularly?

A4: Neglecting regular oil changes can lead to oil thickening and breaking down, losing its lubricating properties. This can cause increased friction, overheating, sludge buildup, and eventually severe engine damage, potentially leading to costly repairs or engine failure. — Transdev Contact: Phone Numbers & Support

Q5: Is it okay to mix synthetic and conventional oil?

A5: While modern synthetic blends allow for mixing, it's generally best to avoid mixing different types of oil if possible. If you need to top up, using the same type and viscosity of oil is ideal. If you must mix, using a full synthetic 0W-20 is recommended to maintain the highest level of protection.

Conclusion

Maintaining the correct oil type and level in your 2014 Subaru Forester is a straightforward yet critical aspect of vehicle care. By consistently using 0W-20 full synthetic oil that meets API SN (or later) and ILSAC GF-5 (or later) specifications, you ensure optimal engine performance, protection, and longevity. Regularly checking your oil level and adhering to the recommended oil change schedule, especially under severe driving conditions, will help prevent premature wear and keep your Forester running reliably. — Used Cars For Sale In Salt Lake City: Your Guide
