Subaru Outback Engine Oil Guide Malaysia

The FB25 2.5L boxer in BS Outback models takes 0W-20 or 5W-30 fully synthetic oil, with a capacity of approximately 5.1 litres including the filter. The CB18 1.8T turbo in BT models requires 0W-20 fully synthetic only, with a capacity of approximately 4.8 litres; the turbo demands high-quality oil to protect bearings and prevent sludge. Both engines use a 10,000 km change interval under normal Malaysian conditions.
