One of the most critical aspects of your Forester’s engine health is selecting the right type of oil. But with so many options on the market, how do you know which one to choose?
In this article, we’ll provide you with a comprehensive guide to help you select the best oil for your 2018 Subaru Forester 2.5i engine. From understanding the different types of oil available to choosing the right viscosity, we’ve got you covered.
Key Takeaways
- The 2018 Subaru Forester 2.5i engine requires synthetic oil with a viscosity of 0W-20.
- Using the wrong type or viscosity of oil can damage your engine and void your warranty.
- Regular oil changes are essential for protecting your engine and optimizing performance.
- Be sure to follow Subaru’s maintenance schedule and recommendations to ensure your vehicle’s longevity.
Understanding Oil Types
Before we dive into which oil is best suited for your Forester, let’s start by understanding the different types of oil available. Here are the most common options:
Conventional Oil
Conventional, or mineral-based, oil is the most basic type of oil available. It’s made from refined crude oil and contains additives that help it lubricate engine parts and resist breakdown. While it’s an affordable option, conventional oil doesn’t offer the same level of protection and longevity as synthetic oils.
Synthetic Blend Oil
Synthetic blend oil is a combination of conventional and synthetic oils. It offers better performance than conventional oil, but not as much as full synthetic oil. It’s a good option for those who want an oil that’s more affordable than full synthetic but still offers better protection than conventional oil.
Full Synthetic Oil
Full synthetic oil is the highest quality oil on the market. It’s made from a combination of synthetic compounds and additives that provide superior lubrication, performance, and engine protection. It’s also more expensive than conventional or synthetic blend oils.
What Type of Oil Does a 2018 Subaru Forester 2.5i Engine Need?
Now that we understand the different types of oil available, let’s talk about which one is best for the 2018 Subaru Forester 2.5i engine. According to Subaru, this vehicle requires synthetic oil with a viscosity of 0W-20. This means that you should use a full synthetic oil with a viscosity rating of 0W-20 to ensure optimal engine performance and protection.
Why Synthetic Oil?
You may be wondering why synthetic oil is required for the 2018 Subaru Forester 2.5i engine. Synthetic oil has several benefits over conventional oil, including:
- Better engine protection: Synthetic oil is formulated with advanced additives that provide superior protection against engine wear and tear.
- Improved fuel efficiency: Synthetic oil reduces engine friction, which can improve fuel efficiency and save you money at the pump.
- Extended oil change intervals: Synthetic oil lasts longer than conventional oil, which means you can go longer between oil changes.
- Better performance in extreme temperatures: Synthetic oil performs better in extreme temperatures, making it an ideal choice for regions with extreme climates.
The Importance of Regular Oil Changes
No matter which type of oil you choose, it’s essential to keep up with regular oil changes. Over time, oil breaks down and becomes less effective at lubricating engine parts. This can lead to increased engine wear and tear, reduced fuel efficiency, and even engine failure.
Subaru recommends changing the oil in your 2018 Forester 2.5i every 6,000 miles or 6 months, whichever comes first. However, if you frequently drive in extreme temperatures, tow heavy loads, or engage in stop-and-go driving, you may need to change your oil more frequently.
Choosing the Right Viscosity
When selecting a synthetic oil for your Forester, it’s essential to choose the right viscosity. Viscosity refers to how easily the oil flows through the engine. The viscosity rating is usually listed in the format of "xW-y," where x represents the oil’s cold-weather performance and y represents its performance in high temperatures.
For the 2018 Subaru Forester 2.5i engine, Subaru recommends a viscosity rating of 0W-20. This means that the oil has excellent cold-weather performance and excellent high-temperature performance. Using an oil with a different viscosity rating can damage your engine and void your warranty.
Frequently Asked Questions
