Buick Enclave Oil Change Interval & Oil Type
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25
When to change the oil on a 2018-2024 (3.6L V6 era; 2025+ switched to 2.5L turbo) Buick Enclave, and what oil it takes.
| Oil change interval | GM Oil Life System ~7,500 mi; by the monitor or at least yearly |
|---|---|
| Engine / oil | 3.6L V6 (LFY), 0W-20 dexos1 Gen 3, 9-speed auto |
| Oil filter | Replace with every oil change |
Buick Enclave note: GM's high-feature 3.6 V6 has a history of timing-chain stretch on earlier versions — on-time (or early) oil changes are the single best prevention. The 2025+ Enclave dropped the V6 for a 2.5L turbo, so this applies to 2018-2024.
