Buick Encore GX Oil Change Interval & Oil Type
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25
When to change the oil on a 2020-2025 Buick Encore GX, and what oil it takes.
| Oil change interval | GM Oil Life System ~7,500 mi; many shorten to ~5,000 mi to protect the wet belt |
|---|---|
| Engine / oil | 1.2L turbo 3-cyl (LIH, WET belt) or 1.3L turbo 3-cyl (L3T, chain); 0W-20 dexos1 Gen 3; CVT (FWD) or 9-speed auto (AWD) |
| Oil filter | Replace with every oil change |
Buick Encore GX note: Mechanically the Trailblazer's upscale twin. The 1.2L uses a wet belt-in-oil timing belt (~150k) — keep dexos1 Gen 3 oil and disciplined changes; the 1.3L uses a chain. AWD gets the 9-speed auto instead of the CVT.
