Complete Oil Specifications
Your 2023 Jeep Grand Cherokee 4xe requires 5W-30 full synthetic oil meeting FCA MS-13340 — not the 0W-30 used in the non-PHEV Cherokee 2.0T. The Grand Cherokee 4xe Hybrid Supplement specifies 5W-30 and a 5.0-quart capacity that differs from the non-PHEV version.

Why 5W-30 with MS-13340 is Critical for This Engine
The GME T4 2.0L in the Grand Cherokee 4xe is the same turbocharged four-cylinder used in other Jeep products, but in PHEV configuration it operates in a unique thermal cycle. The combustion engine starts and stops frequently as the system transitions between EV-only and hybrid mode, and it often restarts cold after sitting while the battery depletes. FCA MS-13340 was written for high-strung MultiAir turbo engines and addresses their specific oxidation resistance and LSPI protection requirements. The 4xe supplement specifies 5W-30 (not 0W-30) because the PHEV’s thermal management system maintains the engine at a more consistent temperature range, reducing the cold-cranking advantage of 0W-30.
Using incorrect oil will:
- ❌ Risk MultiAir hydraulic actuator degradation if viscosity is too thin at temperature
- ❌ Fail to meet FCA MS-13340 if generic API SP oil is substituted
- ❌ Accelerate turbocharger bearing wear during the frequent cold restarts of PHEV operation
Jeep-Approved Oil Brands
-
✅ Pennzoil Ultra Platinum 5W-30 (FCA MS-13340)
-
✅ Mobil 1 Extended Performance 5W-30
-
✅ Castrol EDGE 5W-30
-
✅ Valvoline Advanced Full Synthetic 5W-30
-
✅ Mopar 5W-30 Full Synthetic (FCA MS-13340)
Confirm FCA MS-13340 certification on the label. This spec is required — API SP alone does not qualify.
Severe Service Check
Use the 5000-mile interval if you:
- Drive primarily in EV mode with infrequent engine starts (oil degrades by time, not just miles)
- Tow or haul near max payload
- Drive in sustained temperatures above 95°F or below 10°F
- Operate frequently in stop-and-go traffic
Installation Details
Drain Plug Torque: 20 ft-lbs ⚠️ Low torque spec — the 4xe uses an aluminum pan. Replace the drain plug gasket at every service and use a torque wrench.
OEM Filter: Mopar 68092968AA

Pro Tip: Before draining, switch the 4xe to “Run” mode with the engine confirmed off. The PHEV system can auto-start the combustion engine if HVAC is active. Disable cabin climate before beginning service to prevent unexpected restarts.
FAQs
What oil does a 2023 Jeep Grand Cherokee 4xe take? 5W-30 full synthetic oil meeting FCA MS-13340.
How many quarts does it need? 5.0 quarts with a new filter, 4.7 without.
Is the 4xe oil spec the same as the regular Grand Cherokee 3.6L V6? No. The 3.6L Pentastar Grand Cherokee uses 0W-20 MS-6395. The 4xe uses 5W-30 MS-13340 — a completely different standard.
Does the PHEV system change when I need an oil change? Yes — change the oil based on time as well as miles. If you drive mostly in EV mode, you may reach 12 months before 10,000 miles. Change by whichever comes first.
How often should I change the oil? Every 10000 miles or 12 months, whichever comes first. Use 5000 miles for severe service.
