Fontana Chrysler Dodge Jeep RAM
Finding the right oil for your Jeep Wrangler matters more than most maintenance decisions. Use the wrong viscosity or capacity, and you’re shortchanging engine protection — especially when you’re off-roading the trails around Fontana or battling the summer heat of the Inland Empire, where engine temperatures run high and oil degrades faster than in moderate climates.
This guide covers the recommended Jeep Wrangler oil type and capacity for every engine from 2007 through 2026, including the Jeep Gladiator. Find your year and engine below, then schedule your next oil change with our certified Jeep technicians at Fontana Chrysler Dodge Jeep Ram.
Use the table below to quickly find the recommended oil type and capacity for your specific Jeep Wrangler model year and engine. Always confirm specifications in your owner’s manual.
| Engine | Model Years | Generation | Recommended Oil | Capacity (w/ filter) |
|---|---|---|---|---|
| 2.0L Turbo 4-cyl | 2021–2026 | JL | SAE 5W-30 Full Synthetic (API SP/GF-6A) | 5.5 qts |
| 2.0L Turbo 4-cyl | 2019–2020 | JL | SAE 5W-30 Full Synthetic (API SN Plus) | 5.5 qts |
| 3.6L Pentastar V6 | 2018–2026 | JL | SAE 0W-20 Full Synthetic (API Starburst) | 5 qts |
| 3.6L Pentastar V6 | 2012–2018 | JK | SAE 5W-20 Full Synthetic | 5 qts |
| 3.6L Pentastar V6 | 2007–2011 | JK | SAE 5W-20 Conventional or Synthetic | 5 qts |
| 3.0L EcoDiesel V6 | 2020–2026 | JL | SAE 5W-40 Full Synthetic Diesel | 9 qts |
| 3.8L V6 | 2007–2011 | JK | SAE 5W-20 Conventional or Synthetic | 5 qts |
| 6.4L HEMI V8 | 2021–2026 | JL | SAE 0W-40 Full Synthetic (API Starburst) | 7 qts |
The 2024 and 2025 Jeep Wrangler share the same oil specifications. Jeep recommends Mopar® MaxPro full-synthetic oil for all current Wrangler engines:
Mopar® API SP/GF-6A Certified SAE 5W-30 Full Synthetic — 5.5 quarts with filter.
Mopar® SAE 0W-20 Full Synthetic — must carry the API Starburst trademark — 5 quarts with filter.
Mopar® SAE 0W-40 Full Synthetic — must carry the API Starburst trademark — 7 quarts with filter.
The 2022 and 2023 Wrangler JL use the same oil specifications as the 2024 model. Refer to the 2024–2025 section above for complete engine-by-engine guidance.
The 2021 Wrangler JL shares specifications with the 2022–2024 models:
SAE 5W-30 Full Synthetic (API SP/GF-6A) — 5.5 quarts with filter.
SAE 0W-20 Full Synthetic (API Starburst) — 5 quarts with filter.
The 2020 Wrangler JL introduced the EcoDiesel engine alongside the existing 3.6L and 2.0L options:
The EcoDiesel requires a European-specification 5W-40 synthetic diesel oil — not the standard full synthetic used in gas-powered Wranglers. Using the wrong oil type in the EcoDiesel can cause turbocharger deposits and accelerated wear. Jeep recommends an oil change interval of approximately 10,000 miles for EcoDiesel-equipped Wranglers, though severe-duty driving (towing, off-road) warrants more frequent service. Our service team at Fontana Chrysler Dodge Jeep Ram stocks the correct European-spec 5W-40 to ensure your EcoDiesel is serviced to factory standards.
The 2019 Wrangler JL was the second model year of the current generation:
2018 was a transition year — the JL generation launched alongside the outgoing JK. Check your door jamb sticker to confirm your generation before selecting oil:
The 2017 Wrangler JK with the 3.6L Pentastar V6 requires SAE 5W-20 Full Synthetic oil. Capacity is 5 quarts with filter.
The 2016 Wrangler JK also uses the 3.6L Pentastar V6. Recommended oil is SAE 5W-20 Full Synthetic, 5 quarts with filter. While conventional SAE 5W-20 is technically acceptable, full synthetic is strongly recommended — particularly in Southern California, where summer temperatures routinely stress engine oil beyond what conventional formulas handle well.
The Jeep Gladiator shares its engine platform with the Wrangler JL. Here are the recommended oil specs:
| Engine | Model Years | Generation | Recommended Oil | Capacity (w/ filter) |
|---|---|---|---|---|
| 3.6L Pentastar V6 | 2019–2026 | JT | SAE 0W-20 Full Synthetic (API Starburst) | 5 qts |
| 3.0L EcoDiesel V6 | 2021–2023 | JT | SAE 5W-40 Full Synthetic Diesel | 9 qts |
The 2016 Jeep Wrangler JK with the 3.6L V6 takes SAE 5W-20 Full Synthetic oil. Capacity is 5 quarts with a new filter.
The Jeep Wrangler JL (2018–present) uses SAE 0W-20 Full Synthetic for the 3.6L V6, and SAE 5W-30 Full Synthetic for the 2.0L turbo engine.
The Jeep Wrangler JL with the 2.0L turbocharged 4-cylinder engine requires SAE 5W-30 Full Synthetic oil certified to API SP/GF-6A. Capacity is 5.5 quarts with filter.
Jeep recommends Mopar® MaxPro full-synthetic oil for all Wrangler models. If using a third-party brand, ensure it carries the correct API certification for your engine (API Starburst for V6 models, API SP/GF-6A for the 2.0L turbo, and European-spec MS-12991 for the EcoDiesel). Brands like Pennzoil Platinum, Mobil 1, and Castrol Edge are widely used by Wrangler owners.
Using full-synthetic oil, Jeep recommends an oil change every 7,500 miles or about once to twice a year depending on driving habits. If you regularly off-road in the Inland Empire, tow frequently, or drive in extreme summer heat, consider servicing closer to the 5,000–6,000-mile mark. EcoDiesel owners: your interval is approximately 10,000 miles under normal conditions.
Conventional oil may be used in older JK-generation Wranglers in a pinch, but Jeep strongly recommends full-synthetic for all current models — and it’s essentially required for the EcoDiesel. Full synthetic delivers better protection, longer intervals, and improved performance under the demanding conditions Wranglers are built for.
