Oil specification for the 1.4L Turbo engine
Why the right oil matters and how GM frames the specification:
Dexos1 Gen 2 certification
Dexos1 Gen 2 is GM’s approved oil standard, designed to meet modern engine needs and support warranty terms.
Viscosity and climate considerations
0W-20 is the recommended viscosity for most markets to optimize cold-start performance and fuel economy. In some climates, GM may approve alternate viscosities within the Dexos1 Gen 2 family, but 0W-20 remains the standard recommendation for the Encore in typical conditions.
What to buy
Before shopping, use this guidance to select the right products:
- Dexos1 Gen 2 certified synthetic oil
- Viscosity: 0W-20
- Fully synthetic preferred; synthetic-blend is acceptable only if approved by GM for your vehicle
- Oil filter compatible with the 1.4L Turbo engine
- Oil capacity is about 4.5 quarts with filter; check the owner's manual for the exact figure
Having the right oil and filter helps maintain engine health and keeps warranty terms intact.
Maintenance intervals and tips
- Follow the owner's manual for oil-change intervals. With Dexos1 Gen 2 0W-20 synthetic, many owners see intervals around 7,500 miles under normal driving; harsher conditions may require more frequent changes.
- Regularly check the oil level between changes and top up if needed.
- Always replace the oil filter at each interval to ensure proper filtration.
Note that regional guidelines and vehicle configurations can vary; consult the owner's manual or a Buick service advisor for your specific vehicle.
Summary
The 2019 Buick Encore calls for Dexos1 Gen 2 certified synthetic oil with a 0W-20 viscosity. Plan to use roughly 4.5 quarts with a new filter, and adhere to the service intervals and climate recommendations outlined in the owner's manual. When in doubt, verify with official GM documentation or your Buick dealer.
