5w-30 oil is suggested for the 2018 Subaru Legacy 3.5R Limited. This 3.5 liter engine Legacy hold 6.9 quarts of oil. The rest of the 2018 Subaru Legacy's, The 2.5i, 2.5i Limited, 2.5i Premium and 2.5i Sport are recommended to use 0W-20 motor oil. Since the engine is smaller at 2.5 liters, it also holds less oil. These trims are filled with 5.1 quarts.
What happens if you use 5w-30 oil for the 2.5i,2,5 limited Subaru Legacy 2018? I did it awhile ago I bought one in Walmart and ask an attendant he looked at his phone and suggested the 5W-30
