Pro Tips
Model-specific guidance from owner experience and service bulletins.
- 01
Subaru requires that all four tires be within 1/32" of the same tread depth — mismatched tires damage the AWD center differential.
- 02
Use Subaru ATF for CVT — aftermarket fluids can damage the transmission.
- 03
Check coolant reservoir level weekly if you have a pre-2015 EJ engine — early leak detection saves the head gasket.
