Cadillac XT5 Oil Change Interval & Oil Type
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25
When to change the oil on a 2017-2024 Cadillac XT5, 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 (LGX) or 2.0L turbo (LSY); 0W-20 dexos1 Gen 3; 8/9-speed auto |
| Oil filter | Replace with every oil change |
Cadillac XT5 note: The 2.0L turbo needs spark plugs much sooner (~60,000 mi) than the 3.6L V6 (~97,500 mi) — turbo heat and boost foul plugs faster, so engine choice changes the maintenance cost.
