Most 2017 Subaru Legacy models with the 2.5-liter engine require 0W-20 synthetic motor oil, while models with the 3.6-liter engine require 5W-30 synthetic motor oil. Always confirm the exact specification in your owner's manual or with a Subaru dealer.
Engine options and oil requirements
The 2017 Legacy was offered with two gasoline engines, and the oil specification depends on which one your car has. Here is a quick reference by engine.
Quick reference by engine:
- 2.5-liter engine (FB25): 0W-20 full synthetic motor oil.
- 3.6-liter engine (EZ36): 5W-30 full synthetic motor oil.
Oil type must match the engine to ensure proper lubrication, performance, and warranty compliance. Always check your vehicle’s manual or confirm with a dealer if you’re unsure which engine your Legacy uses.
Maintenance notes and cautions
Oil viscosity and type are engine-specific. Use the grade specified for your engine to maintain optimal lubrication. For the most accurate guidance, refer to the owner's manual or a Subaru-certified technician, especially if your vehicle has undergone recent modifications or operates in extreme temperatures.
Summary
In summary, the 2017 Subaru Legacy uses 0W-20 synthetic oil for the 2.5L engine and 5W-30 synthetic oil for the 3.6L engine. Always verify the exact specification in your owner's manual or with a dealer to account for your specific model and conditions.
What is the best oil for a Subaru Legacy?
For example, a Subaru Legacy produced between 2013 and 2021 will need 0W-20 synthetic oil. By contrast, any Subaru Legacy produced between 2005 and '10, these models will use synthetic 5W-30. Your engine type can also have an impact. For instance, a Legacy with a 6-cylinder engine might use 5W-30 instead of 0W-20.
What oil should I put in my 2017 Subaru Legacy?
