The Subaru Outback uses 0W-20 full synthetic oil on the 2.5L FB25 (5W-30 on the 2.4L turbo) changed every 6,000 miles/6 months - a shorter interval than most. Key services include iridium spark plugs and a rear-differential fluid change at 60,000 miles, a Lineartronic CVT fluid drain-and-fill (recommended despite the lifetime label), brake fluid every 30,000 miles, and a coolant flush at 137,500 miles. Average annual cost: $400-$550.
