Most Subarus have the oil type printed on the oil cap – it will likely be 5W-20, 5W-30, 5W-40, 10W-30 or 10W-40. If it isn’t printed on the oil cap, check your owner’s manual for the exact type before adding new oil.
We recommend wearing safety glasses whenever you are working under your Legacy. You never know what could be dripping down from the engine, battery acid, engine coolant, brake fluid, etc. All of these fluids are extremely harmful to your eyes and skin so it is important to protect yourself.

Service Bulletin 02-103-07 from Subaru identifies a manufacturing design issue with early oil mesh screen clogging inside the turbocharging system’s oiling system, which is supplied to all model turbocharged vehicles. A clogged screen will cause oil deprivation and failure of the turbocharger.
In February 2015, the National Highway Traffic and Safety Administration (NHTSA) announced that multiple complaints were filed against Subaru of America. The NHTSA said that oil and filter changes for 2010 MY and earlier turbocharged engines should be done every 3,750 miles (6,000 km), or 3 3/4 months, while all 2011 MY turbocharged engines should change their oil at 7,500 miles (12,000 km) intervals or 7 1/2 months. Synthetic oil is now required by law in all states except California. Because of the concerns addressed in this document, Carfluidfinder advises following Subaru’s drain interval recommendations.

How Much Oil Does A Subaru Legacy Take?
New 2.5L Subaru Legacy takes 4.4 quarts of oil 0W-20 oil. A 2.4L Subaru Legacy takes 4.8 quarts of 0W-20 oil.
Synthetic oil is now required by law in all states except California. Because of the concerns addressed in this document, Carfluidfinder advises following Subaru’s drain interval recommendations. Newer models require the best motor oils that are recommended to use which include 0W-20 oil.
The Oil Is Black and Gritty
New oil is the color of honey, but after just a few weeks of use, it begins to turn dark. This color change is acceptable, but as soon as you see particles mixed in with that darker-colored oil, it’s time for an oil change. These particles can get stuck in your engine and overwhelm your oil filter, which will result in clogging and unnecessary buildup. Has your oil changed before this becomes a problem?
The Engine Runs Loudly
Oil is an engine lubricant, preventing parts from grinding against one another. The dry friction of the constantly moving parts gives off a metallic grinding sound. If your engine begins to run louder and makes abnormal and unpleasant noises, don’t delay that oil change any longer or your Subaru could suffer serious consequences.
