Maintaining your Subaru requires regular oil and filter changes. This comprehensive guide will walk you through everything you need to know, from choosing the right oil and filter to performing the change yourself. Whether you're a seasoned mechanic or a novice DIY enthusiast, this guide will empower you to keep your Subaru running smoothly for years to come.
Understanding Subaru's Oil Requirements
Subaru engines, known for their reliability and performance, have specific oil requirements. Ignoring these recommendations can lead to decreased engine life and potential damage. Your owner's manual is the ultimate authority, clearly specifying the recommended oil type, viscosity, and capacity for your particular Subaru model and year. Generally, Subaru recommends using high-quality synthetic oil for optimal performance and protection.
Key Factors to Consider When Choosing Oil:
-
Viscosity: This refers to the oil's thickness at different temperatures. The correct viscosity is crucial for proper lubrication and engine protection. Your owner's manual will specify the recommended viscosity grade (e.g., 0W-20, 5W-30). Using the wrong viscosity can negatively impact engine performance and fuel economy.
-
Oil Type: Subaru generally recommends using synthetic oil, which offers superior performance and protection compared to conventional oil. Synthetic oil can withstand higher temperatures and provide better lubrication, leading to extended engine life.
-
Oil Capacity: The amount of oil your Subaru's engine requires varies depending on the model and year. Always refer to your owner's manual for the precise oil capacity. Using too little or too much oil can be detrimental to your engine.
Selecting the Right Oil Filter
The oil filter plays a crucial role in removing contaminants from your engine oil, preventing wear and tear. Choosing a high-quality filter is just as important as choosing the right oil. While Subaru offers genuine oil filters, several reputable aftermarket brands offer comparable quality at potentially lower prices.
Factors to Consider When Choosing an Oil Filter:
-
Compatibility: Ensure the filter is compatible with your Subaru's make, model, and year. The filter's specifications should match those listed in your owner's manual.
-
Filter Type: Most Subaru oil filters are spin-on filters, meaning they are easily screwed on and off. Check your owner's manual to confirm the type of filter your vehicle uses.
-
Quality: Look for filters from reputable manufacturers known for their quality and reliability. Read reviews and compare different brands to find a filter that meets your needs and budget.
Performing the Oil and Filter Change: A Step-by-Step Guide
Changing your Subaru's oil and filter is a relatively straightforward process, even for beginners. However, always prioritize safety and follow these steps carefully:
Tools and Materials You'll Need:
- New oil (refer to your owner's manual for the correct type and amount)
- New oil filter (ensure compatibility with your Subaru model)
- Oil filter wrench
- Wrench for the drain plug
- Drain pan
- Funnel
- Rags or shop towels
- Gloves
Step-by-Step Instructions:
- Warm up the engine: Run the engine for a few minutes to warm the oil, making it flow more easily.
- Secure your vehicle: Park on a level surface and engage the parking brake.
- Locate the drain plug: Position the drain pan under the oil drain plug and carefully remove the plug using the correct wrench.
- Drain the oil: Let the oil drain completely. This may take 15-20 minutes.
- Replace the drain plug: Once the oil has drained, replace the drain plug and tighten it securely.
- Locate the oil filter: Position the drain pan beneath the oil filter and use the oil filter wrench to remove the old filter.
- Install the new filter: Lightly lubricate the rubber gasket on the new filter with fresh oil and screw it on by hand until snug.
- Add new oil: Using a funnel, carefully pour the correct amount of new oil into the engine (refer to your owner's manual).
- Check the oil level: Use the dipstick to check the oil level and add more if necessary.
- Start the engine: Run the engine for a few minutes and then check for any leaks.
- Dispose of used oil properly: Take the used oil and filter to a recycling center or auto parts store that accepts used oil.
