The Jeep EXF – Petrol (FCA) is a 2,995 cc, V6 turbocharged engine produced between 2019 and 2023. It features gasoline direct injection (GDI), twin-scroll turbochargers, and dual overhead camshafts (DOHC). This powerplant delivers 268–295 kW (365–400 PS) and 500–520 Nm of torque, with its twin-turbo design providing seamless power delivery across the rev range.
Fitted exclusively to high-performance variants like the Wrangler Rubicon 392 and Grand Cherokee Trackhawk, the EXF engine was engineered for extreme off-road capability and track-ready acceleration. Emissions compliance was achieved through a gasoline particulate filter (GPF) and sophisticated engine management, allowing it to meet stringent Euro 6d standards across its production run.
One documented concern is premature wear of the high-pressure fuel pump cam follower, which can lead to pump failure. This issue, addressed in FCA Service Bulletin 21-067-23, is linked to insufficient lubrication under high-load conditions. In 2022, FCA introduced a revised cam follower design with improved oiling passages.
All production years 2019–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/FCA/8765).
The Jeep EXF – Petrol (FCA) is a 2,995 cc V6 twin-turbocharged engine engineered for high-performance SUVs (2019-2023). It combines gasoline direct injection with twin twin-scroll turbochargers to deliver explosive acceleration and sustained high-RPM power. Designed to meet Euro 6d standards, it balances brute force with regulatory compliance.

The twin-turbo V6 provides relentless acceleration ideal for track or desert running but demands strict adherence to 10,000 km oil change intervals to prevent turbo and fuel pump wear. FCA MS-12991 (5W-40) oil is critical due to its specific low-SAPS formulation protecting the GPF. Extended low-load operation should be avoided to facilitate passive GPF regeneration. The high-pressure fuel pump requires premium, high-detergent fuel to prevent cam follower wear. Post-2022 models feature a revised cam follower; pre-2022 units should be inspected per FCA SIB 21-067-23 if fuel pressure irregularities occur.
Oil Specs: Requires FCA MS-12991 specification (FCA Owner's Manual). Equivalent to ACEA C2/C3 low-SAPS oils.
Emissions: Euro 6d certification applies to all model years 2019-2023 (VCA Type Approval #VCA/FCA/8765).
Power Ratings: Measured under SAE J1349 standards. Output varies by model application and ECU tune (FCA TIS Doc. FCA-ENG-9110).

The Jeep EXF – Petrol (FCA) was used across Jeep's Performance 4x4 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts and a bespoke intake system for the Wrangler Rubicon 392 and a unique exhaust manifold for the Grand Cherokee Trackhawk-with no major facelift revisions affecting core interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the left cylinder bank, near the alternator (FCA TIS FCA-ENG-9105). The 8th VIN digit indicates engine displacement ('F' for 3.0L). All EXF petrol engines feature a cast aluminum intake manifold with 'Twin-Turbo' branding and a centrally mounted GPF canister in the exhaust. Critical differentiation from the 5.7L/6.4L HEMI: EXF has six cylinders and twin turbos; HEMI engines are naturally aspirated or supercharged V8s. Service parts are generally consistent across model years, but ECU software is model-specific (FCA SIB 22-120-22).
The EXF – Petrol (FCA)'s primary reliability risk is high-pressure fuel pump cam follower wear, with elevated incidence in vehicles subjected to sustained high-RPM operation. FCA internal data indicates a measurable increase in warranty claims for fuel system faults after 40,000 km in track-driven vehicles, while UK DVSA records show no significant correlation with MOT failures. Extended low-load operation inhibits GPF regeneration, making periodic highway driving critical.
Analysis derived from FCA technical bulletins (2021-2023) and UK DVSA failure statistics (2022-2024). Repair procedures should follow manufacturer guidelines.
