Jeep Gladiator Oil Change Interval & Oil Type
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-18
When to change the oil on a 2020-2024 (JT) Jeep Gladiator, and what oil it takes.
| Oil change interval | 6,000-10,000 mi (gas); diesel per monitor; off-road sooner |
|---|---|
| Engine / oil | 3.6L Pentastar V6 or 3.0L EcoDiesel; 0W-20 (gas) / 5W-40 (diesel); 8-speed auto / 6-speed manual |
| Oil filter | Replace with every oil change |
Jeep Gladiator note: Like the Wrangler it's based on, the defining maintenance is gear oils — front/rear differential and transfer-case fluid every ~30k (or after any water crossing), not the chain-driven engine.
