The 2014 Subaru Outback is offered with two different engine options. The first one is a 2.5-liter model that requires 5 quarts of oil, while the second is a 3.6-liter engine that needs 7 quarts of oil. Subaru advises using a 0W-20 viscosity oil for the smaller engine and a SAE 5W-30 viscosity oil for the larger engine. They highly recommend using full synthetic oils for better protection, durability, and efficiency compared to semi-synthetic oils. It is recommended to change the oil every 3500 to 5000 miles and to replace the oil filter during each oil change to maintain the car's performance.
The 2014 Subaru Outback can utilize a synthetic engine oil that meets the same requirements as conventional engine oil. If you opt for synthetic oil, ensure it matches the classification, viscosity, and grade stated in the Owner's Manual, and stick to the recommended oil and filter change intervals in the maintenance schedule. For the 2014 Subaru Outback 2.5L model, Subaru recommends using 0W-20 oil with a capacity of 5.1 US quarts (4.8 liters). On the other hand, for the 2014 Subaru Outback 3.6L model, it's suggested to go with 5W-30 oil with a capacity of 6.9 US quarts (6.5 liters).
