The Jeep Wrangler offers several engines, and each has a distinct oil grade and capacity, so it is important to match your exact powertrain. The popular 3.6L Pentastar V6 uses 0W-20, while the 2.0L turbo uses a thicker 5W-40. Here is the breakdown by engine and year.
| Engine / Years | Oil type | Capacity | Interval |
|---|---|---|---|
| 3.6L V6 2018-2025 | 0W-20 synthetic | 5.0 qt | 10,000 mi |
| 3.6L V6 2012-2017 | 5W-20 or 0W-20 | 6.0 qt | 8,000-10,000 mi |
| 2.0L turbo 2018-2025 | 5W-40 synthetic | 5.0 qt | 10,000 mi |
| 4.0L inline-6 pre-2007 | 5W-30 or 10W-30 | 6.0 qt | 3,000-5,000 mi |
The 3.6L Pentastar V6 in modern Wranglers uses 0W-20 full synthetic meeting the Chrysler MS-6395 specification. The 2.0L turbo four-cylinder uses 5W-40 full synthetic, a notably thicker grade. The 3.0L EcoDiesel uses a specific diesel-rated oil per the manual.
Older Wranglers with the 3.8L V6 or the 4.0L inline-six used 5W-20 or 10W-30, so check your year and engine.
The 3.6L V6 holds about 5 to 6 quarts depending on year (early Pentastars took 6 quarts, later ones about 5 quarts). The 2.0L turbo holds roughly 5 quarts. Always confirm on the dipstick, since the 3.6L capacity changed across model years.
The Wrangler uses a cartridge-style oil filter on top of the engine for the Pentastar, which makes it clean and easy to reach. Gather the correct grade of synthetic, the right filter and O-ring, and the proper tools. Reset the oil-change indicator through the dash menu after finishing.
