Use SAE 5W-30 viscosity grade engine oil that meets the dexos1 specification in the 2015 Buick Encore. An engine oil with a viscosity of SAE 0W-30 can be used where the temperatures fall below ˆ’20 °F. When the oil is completely drained from the engine and the filter has been replaced, the car can hold 4.2 quarts of oil. You should check the engine oil level often, once per week or every time You put gas in the tank. The Encore has an engine oil life system which monitors the engine use and driving style to determine when an oil change is due. When CHANGE ENGINE OIL SOON message comes on have Your oil changed as soon as possible within the neXT600 miles.
