What is the recommended engine oil for Subaru?
The recommended engine oil for Subaru vehicles is 5W-30 synthetic oil. This oil grade provides the optimal lubrication and protection for Subaru's boxer engines, which have unique design characteristics that require a specific type of motor oil.
Understanding Subaru's Engine Oil Requirements
Subaru's horizontally-opposed "boxer" engines have a different configuration compared to traditional inline or V-shaped engines. This unique design requires a motor oil that can effectively lubricate the engine's moving parts and withstand the specific stresses placed on the oil. Using the wrong oil can lead to increased wear, reduced fuel efficiency, and even engine damage over time.
Recommended 5W-30 Synthetic Oil
Subaru recommends using a 5W-30 synthetic motor oil for most of their vehicle models. This oil grade provides the following benefits:
- Viscosity: The 5W-30 viscosity ensures the oil flows easily at low temperatures during cold starts, while also maintaining sufficient thickness at high operating temperatures.
- Synthetic Formulation: Synthetic oils offer superior performance and protection compared to conventional mineral-based oils, with improved resistance to oxidation, thermal breakdown, and sludge buildup.
- Compatibility: 5W-30 synthetic oil is specifically engineered to meet Subaru's lubrication requirements and is approved for use in their boxer engines.
It's important to always refer to your Subaru's owner's manual for the recommended oil type and viscosity grade, as requirements may vary slightly between model years and engine configurations.
Maintenance and Oil Changes
Subaru recommends changing the engine oil and filter every 6 months or 6,000 miles, whichever comes first. Using the correct 5W-30 synthetic oil and following the recommended maintenance schedule is crucial for preserving the longevity and performance of your Subaru's engine.
How long can a Subaru go without an oil change?
Miles intervals:
Most Subaru vehicles on the road today should have an oil change performed every 6 months or 6,000 miles – whichever comes first .
What is Subaru certified motor oil?
Synthetic 0W-20 is uniquely formulated to handle the low-friction design of Subaru non-turbocharged engines. Synthetic 5W-30 motor oil is required for 2011 and newer turbo-charged engines, and is recommended for prior year models.
Why do Subarus use so much oil?
Consumer Reports on Subaru Oil Consumption Issues
As a result, the new engine designs suffered restricted oil durability. Some consumer posts suggested that the piston ring design was the source of the problem. As a result, oil bypasses the piston and results in premature combustion.
Can I use 5W20 instead of 0W20?
If SAE 0W-20 synthetic oil is not available, SAE 5W-20 conventional oil may be used. However, it must be replaced with SAE 0W-20 synthetic oil at the next oil change.
Is it bad if I use 5W-30 instead of 0w20?
Using the proper viscosity motor oil will help protect and maintain the performance of your vehicle's engine. Thus, always refer to the manufacturer's recommendation while your vehicle is under warranty. **if you have a car that recommends 0W-20, do not use 5W-30 – back # of vis-grade must match or it is a no-go.
Can I put 5W-30 in my Subaru?
5w-30 is recommended for all Subaru vehicles according to the Subaru.jp website.
