The 2014 Subaru Legacy useS6.9 quarts of oil including the oil filter. Subaru recommends that You use synthetic oil when You need to change it. Synthetic oil is engineered to provide superior protection to Your engine components compared to conventional. Synthetic oil also has the benefit of requiring less frequent oil changes. On average You will only need to change it every 7,500 miles compared to the 3,500 to 5,000 with conventional oil. I recommend that You check Your oil at least once a month to make sure that it is full and free from debris. Oil that is burnt or has visible debris in it should be changed as soon as possible to prevent damage.
ABSOLUTELY DO NOT put 6.9qt of oil in your 2014 subaru legacy 2.5i!!!!! The manual itself calls for only 5.1qt WITH an oil filter change. Putting 6.9qt in your engine will make for a very bad (and smokey) time.

6.9 qts for a 2014 is for 3.6R engines, which are turbocharged. The 2.5i takes 5.1 qts.
