Complete Oil Specifications
Your 2023 Dodge Hornet GT with the 2.0L GME T4 turbocharged engine requires 0W-20 full synthetic oil meeting the FCA MS-13340 specification. This standard supersedes a generic API SP rating — look for the MS-13340 label on the oil bottle, not just the API donut.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |
| FCA Standard | MS-13340 |
| API Rating | API SP / SN PLUS |
| Capacity (with filter) | 5.5 quarts |
| Oil Filter | Mopar MO-339 |
| Normal Interval | Follow Oil Life Monitor max 10,000 miles or 1 year |
Why FCA MS-13340 0W-20 is Critical for the GME T4
The Hornet’s 2.0L GME T4 is Stellantis’s global turbocharged four-cylinder. It uses a twin-scroll turbocharger, direct injection, and a high 10.0:1 compression ratio — a combination that demands LSPI protection and strong thermal stability from its engine oil.
FCA MS-13340 goes beyond API SP by mandating tighter LSPI (Low-Speed Pre-Ignition) inhibition performance and turbocharger deposit-resistance testing. Using generic 0W-20 without the MS-13340 certification risks pre-ignition events that can damage pistons on turbocharged direct-injection engines.
Using incorrect oil will:
- ❌ Risk Low-Speed Pre-Ignition (LSPI) — a catastrophic single-event failure in turbocharged DI engines
- ❌ Allow turbocharger deposits to form under sustained boost operation
- ❌ Potentially void the Stellantis powertrain warranty on a lubrication-related failure

Severe Service Check
The Hornet’s Oil Life Monitor will shorten intervals automatically. Expect earlier changes if you:
- Drive predominantly short trips under 5 miles where the engine rarely fully warms up
- Tow or carry heavy cargo regularly
- Drive in extreme heat above 100°F or cold below 0°F
- Drive in sustained stop-and-go traffic
Installation Details
Drain Plug Torque: 20 ft-lbs The aluminum oil pan uses a low-torque spec. Never exceed 20 ft-lbs or you risk stripping the threads.
OEM Filter: Mopar MO-339
Aftermarket Filters:
-
Mobil 1 M1-113A
-
K&N HP-1017
-
WIX 57060
Pro Tip: The GME T4 oil drain plug is located on the passenger side of the oil pan, recessed behind the front subframe. Access is easier from below on a lift or ramps — budget extra time compared to conventional drain positions.
FAQs
What oil does a 2023 Dodge Hornet 2.0T take? 0W-20 full synthetic oil meeting FCA MS-13340 and API SP.
How many quarts does it need? 5.5 quarts with a new filter.
Can I use 5W-30 if 0W-20 is unavailable? No. The GME T4 is specified for 0W-20 only. Using 5W-30 will impair cold-start turbocharger lubrication and is not approved by Stellantis.
Does the Hornet R/T use the same oil? No. The Hornet R/T uses the larger Hurricane 2.0L engine (GME T-6) which has different oil requirements. This page is for the standard Hornet GT with the GME T4.
How often should I change the oil? Follow the Oil Life Monitor. Do not exceed 10,000 miles or 12 months regardless of what the monitor shows.
