The 2020 Buick Encore GX uses roughly 4.0 to 4.2 quarts of engine oil with a filter, depending on the engine option, and it relies on 0W-20 full-synthetic oil.
This article explains the oil capacity for the Encore GX, notes the engine options that affect the amount, and provides practical guidance for checking and maintaining the oil level.
Engine options and oil capacity
The Encore GX was offered with two turbocharged engines in the 2020 model year. The figures below assume a standard oil change that includes replacing the oil filter. Exact capacity can vary slightly by VIN and production batch, so always confirm with the owner's manual or a GM service bulletin for your specific vehicle.
Before listing the typical capacities, note that published figures generally fall in the range of about 4.0–4.2 quarts. The capacities below reflect common published estimates for each engine.
- 1.3L turbo engine: approximately 4.2 quarts (4.0 liters) of oil with filter
- 1.2L turbo engine: approximately 4.0 quarts (3.8 liters) of oil with filter
These numbers cover a standard oil change that includes replacing the oil filter; actual amounts can vary slightly if the vehicle has special equipment or if you replace the oil drain plug or filter differently. Always verify the level using the dipstick after filling.
Oil grade and service interval
GM commonly recommends 0W-20 full-synthetic oil for the Encore GX’s engines. The typical oil-change interval for normal, non-severe driving conditions is about 7,500 miles (12,000 km), though severe driving conditions may warrant more frequent changes. Always follow the schedule in your owner's manual for your specific vehicle and region.
How to check and top off oil
Park on level ground and turn off the engine. After the engine cools, pull the dipstick, wipe it clean, reinsert it, and check the oil level. If the level is low, add small amounts of 0W-20 synthetic oil and recheck until the dipstick indicates the correct range. Do not overfill, as that can cause engine damage.
Summary
The 2020 Buick Encore GX generally requires about 4.0–4.2 quarts of engine oil with a filter, using 0W-20 full-synthetic oil. The exact quantity depends on which turbo engine your vehicle has (1.3L or 1.2L). For precise figures, consult the owner's manual or GM service information for your VIN, and always verify the level after an oil change.
