The 2024 Outback’s 2.5 L engine needs 0W-20 synthetic oil, which Subaru calls the required oil, and an oil and filter change takes 4.4 US quarts (4.2 L). It tows 2,700 lb with trailer brakes and 1,000 lb without; the 2.4 L turbo tows 3,500 lb. The 18.5-gallon tank takes 87-octane gasoline with no more than 15% ethanol (Subaru).
This page covers the 2024 Outback and Outback Wilderness owner’s manual, and the figures are for the 2.5 L FB25 engine (no turbo). The 2.4 L FA24 turbo’s oil capacity and towing limits are given alongside.
