For the 2014 Subaru Outback, oil choice depends on the engine you have. The 2.5-liter four-cylinder typically requires 0W-20 synthetic oil, while the 3.6-liter flat-six uses 5W-30 synthetic oil. Always confirm with your owner's manual or under-hood oil cap, as specifications can vary by engine and climate.
Subaru’s guidance emphasizes using full synthetic oil that meets API SN or newer and ILSAC GF-5 or newer. The oil should be compatible with the engine's lubrication system and the vehicle's maintenance schedule.
