Complete Oil Specifications
Your 2023 Lincoln Corsair equipped with the 2.0L EcoBoost requires 5W-30 full synthetic oil meeting API SP, ILSAC GF-6A, and Ford’s WSS-M2C946-B1 specification.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 5W-30 |
| API Rating | API SP |
| Ford Spec | WSS-M2C946-B1 |
| Capacity (with filter) | 5.7 quarts |
| Oil Filter | Ford FL-500-S |
| Normal Interval | 10000 miles |
Why 5W-30 WSS-M2C946-B1 is Critical for This Engine
The 2.0L EcoBoost in the Corsair is a turbocharged direct-injection four-cylinder with a twin-scroll turbocharger. Ford’s WSS-M2C946-B1 specification encompasses API SP requirements but adds Ford-specific bench testing for piston cleanliness, turbocharger deposit control, and extended drain interval stability. The 5W-30 viscosity maintains the correct oil film thickness on the twin-scroll turbo’s bearings across the Corsair’s full operating range — from cold Michigan winters to stop-and-go summer heat.
Using incorrect oil will:
- ❌ Accelerate turbocharger bearing wear without the correct anti-wear additives
- ❌ Allow piston deposits under the direct-injection combustion chamber
- ❌ Risk LSPI events in the turbocharged GDI engine with non-SP oil
Lincoln/Ford-Approved Oil Brands
-
✅ Motorcraft Full Synthetic 5W-30 (WSS-M2C946-B1)
-
✅ Pennzoil Platinum Full Synthetic 5W-30
-
✅ Castrol Edge Extended Performance 5W-30
-
✅ Mobil 1 Annual Protection 5W-30
-
✅ Valvoline Advanced Full Synthetic 5W-30
Motorcraft is Ford’s own-brand lubricant and the safest choice for WSS-M2C946-B1 compliance. Major brands including Pennzoil, Castrol, Mobil 1, and Valvoline produce 5W-30 full synthetic formulas that meet this specification — look for it printed on the container.
Severe Service Check
You need the 5000-mile interval if you:
- Make frequent short trips under 5 miles in cold weather
- Drive in heavy urban stop-and-go traffic daily
- Operate with the Corsair’s turbocharged engine under sustained load (mountain passes, highway merges)
- Experience frequent cold starts in sub-freezing temperatures
Installation Details
Drain Plug Torque: 20 ft-lbs The Corsair uses an aluminum oil pan — do not exceed 20 ft-lbs or overtighten with power tools. Always replace the drain plug gasket (Ford part number W705594-S300).

Pro Tip: The 2.0L EcoBoost in the Corsair uses the same FL-500-S spin-on filter as many other Ford/Lincoln applications. The filter is accessible from below and requires a 15/16” or 24mm filter wrench. Ford’s Intelligent Oil-Life Monitor (IOLM) calculates remaining oil life based on engine revolutions, temperature, and load — don’t rely on mileage alone.
FAQs
What oil does a 2023 Lincoln Corsair 2.0L EcoBoost take? 5W-30 full synthetic meeting API SP, ILSAC GF-6A, and Ford WSS-M2C946-B1 specification.
How many quarts does it need? 5.7 quarts with a new filter, 5.3 quarts without.
Can I use 5W-20 instead of 5W-30? No. Lincoln specifies 5W-30 for the 2.0L EcoBoost in the Corsair. 5W-20 does not provide sufficient viscosity for the turbocharged application.
Is synthetic oil required? Yes. Full synthetic is mandatory for the 2.0L EcoBoost and required to achieve the 10,000-mile Intelligent Oil-Life Monitor intervals.
How often should I change the oil? Ford’s Intelligent Oil-Life Monitor will alert you when a change is needed — typically every 10000 miles under normal driving. Never exceed 12 months between changes regardless of mileage.
Does the Corsair Grand Touring PHEV use the same oil? No. The plug-in hybrid Corsair uses a different 2.5L engine with a separate oil specification. This spec applies to the standard 2.0L EcoBoost only.
