Subaru maintenance guides
Subaru's symmetrical AWD and boxer engines make them uniquely capable, but the EJ-series engines are famously sensitive to cooling and oil maintenance.
Subaru Outback
1994–present
0W-20 full syntheticOil: Every 6,000 miles
2020+ Outback with the FA24 engine is dramatically more reliable. Earlier EJ models need strict coolant and oil discipline to avoid head gasket failure.
Subaru Forester
1997–present
0W-20 full syntheticOil: Every 6,000 miles
Foresters are extremely capable but demand rigorous maintenance. Annual maintenance cost around $600 for EJ models; $400 for FB models.
