2017 Subaru Forester 2.5 I Premium Oil Type

Understanding the correct oil type for your 2017 Subaru Forester 2.5i Premium is crucial for maintaining its performance, longevity, and overall health. Using the wrong oil can lead to a variety of issues, from decreased fuel efficiency to serious engine damage. This article provides a comprehensive guide to the recommended oil type, viscosity, and other important considerations for your vehicle.

The Importance of Using the Right Oil

Your engine relies on oil to lubricate its moving parts, reduce friction, dissipate heat, and remove contaminants. The oil recommended by Subaru is specifically formulated to meet the demands of your 2.5i Premium engine. Deviation from these recommendations can compromise the engine's ability to perform these vital functions effectively.

Here's a closer look at why choosing the right oil is so important:

Reduced Wear and Tear: Proper lubrication minimizes friction between engine components, extending their lifespan and preventing premature wear.
Optimal Engine Performance: The correct oil viscosity ensures proper flow and lubrication, leading to smooth engine operation and optimal performance.
Improved Fuel Efficiency: Using the recommended oil can contribute to better fuel economy by reducing internal engine friction.
Extended Engine Life: Consistent use of the appropriate oil helps maintain engine cleanliness and prevent sludge buildup, prolonging its lifespan.
Warranty Compliance: Using oil that meets Subaru's specifications is essential for maintaining your vehicle's warranty.

Recommended Oil Type and Viscosity for the 2017 Subaru Forester 2.5i Premium

The official recommendation from Subaru for the 2017 Forester 2.5i Premium is 0W-20 synthetic oil. This recommendation is clearly stated in your owner's manual and often on a sticker under the hood. The 0W-20 viscosity provides excellent cold-start protection and maintains adequate lubrication at higher operating temperatures. Always consult your owner's manual for the most up-to-date and specific information for your vehicle.

Why Synthetic Oil? Synthetic oils are engineered to provide superior performance and protection compared to conventional oils. They offer improved resistance to breakdown under high temperatures, better cold-weather flow, and enhanced protection against sludge and deposit formation. Subaru recommends synthetic oil for the 2017 Forester 2.5i Premium to optimize engine performance and longevity.

Understanding Oil Viscosity: 0W-20 Explained

The 0W-20 designation refers to the oil's viscosity, or its resistance to flow. The "0W" indicates the oil's viscosity at cold temperatures (the "W" stands for winter). A lower number means the oil flows more easily at cold temperatures, providing better start-up protection. The "20" indicates the oil's viscosity at operating temperatures. A higher number means the oil is thicker and provides better protection at higher temperatures.

Using a 0W-20 oil ensures that your engine is properly lubricated in both cold and hot conditions, which is particularly important for the Subaru Forester's horizontally opposed "boxer" engine design.

Oil Change Intervals for Your 2017 Subaru Forester 2.5i Premium

Subaru recommends an oil change interval of every 6,000 miles or 6 months, whichever comes first, under normal driving conditions. However, if you frequently drive under severe conditions, such as:

Stop-and-go traffic
Towing a trailer
Driving in dusty or muddy conditions
Frequent short trips

... you may need to change your oil more frequently. Consult your owner's manual for specific recommendations based on your driving habits.

It's always better to err on the side of caution and change your oil more frequently than necessary, especially if you want to maximize the lifespan of your engine.

Checking Your Oil Level

Regularly checking your oil level is essential for maintaining proper engine lubrication. Here's how to do it:

Park your vehicle on a level surface.
Allow the engine to cool down for at least 5 minutes.
Locate the dipstick (usually yellow or orange).
Pull out the dipstick and wipe it clean with a lint-free cloth.
Reinsert the dipstick fully.
Pull the dipstick out again and check the oil level.
The oil level should be between the "Min" and "Max" marks on the dipstick.

If the oil level is low, add the recommended 0W-20 synthetic oil until it reaches the "Max" mark. Avoid overfilling the engine.

Choosing the Right Oil Filter

In addition to using the correct oil type and viscosity, it's also important to use a high-quality oil filter. The oil filter removes contaminants from the oil, preventing them from circulating through the engine and causing wear. Subaru recommends using a genuine Subaru oil filter or a comparable aftermarket filter that meets Subaru's specifications. Using a cheap or inferior oil filter can compromise its ability to effectively filter contaminants, potentially leading to engine damage.

When purchasing an oil filter, make sure it is specifically designed for the 2017 Subaru Forester 2.5i Premium.

Where to Buy Oil and Oil Filters

You can purchase 0W-20 synthetic oil and oil filters at various locations, including:

Subaru dealerships
Auto parts stores (e.g., AutoZone, Advance Auto Parts, O'Reilly Auto Parts)
Online retailers (e.g., Amazon, Walmart)

When purchasing oil online, make sure to buy from a reputable seller to ensure that you are receiving genuine, high-quality oil.

Can You Use a Different Oil Viscosity?

While 0W-20 is the recommended oil viscosity for the 2017 Subaru Forester 2.5i Premium, there may be circumstances where a different viscosity could be considered. However, this should only be done after careful consideration and consultation with a qualified mechanic. Using a different viscosity could potentially affect engine performance, fuel efficiency, and warranty coverage.

In general, it is best to stick to the manufacturer's recommended oil viscosity to ensure optimal engine protection and performance.

Summary

Using the correct oil type and viscosity is essential for maintaining the health and performance of your 2017 Subaru Forester 2.5i Premium. Always use 0W-20 synthetic oil and change your oil and filter regularly according to Subaru's recommendations. By following these guidelines, you can help ensure that your engine runs smoothly and reliably for years to come. Regular maintenance and attention to detail are key to maximizing the lifespan of your vehicle. Consult your owner's manual for the most accurate and up-to-date information specific to your vehicle.
