WSS-M2C947-A is Ford’s specification for 0W-20 synthetic motor oil, part of a broader series of weight-specific standards Ford uses to define oil requirements across its lineup.
Oils meeting this standard are fully synthetic and align with API SN and ILSAC GF-5 performance levels.
This standard was later superseded by WSS-M2C947-B1, which was developed to address Low Speed Pre-Ignition.
LSPI is a combustion event that can cause catastrophic internal damage in turbocharged gasoline direct injection engines, including Ford’s EcoBoost lineup. It occurs when the air-fuel mixture ignites before the spark plug fires, generating pressure spikes the engine isn’t designed to absorb.
WSS-M2C947-A was aligned with API SN and ILSAC GF-5, standards that predate formal LSPI testing requirements.
When API SN Plus was developed to specifically address LSPI, Ford updated the spec to WSS-M2C947-B1. The B1 revision also introduced stricter timing chain wear testing.
If your vehicle originally called for 947-A, an oil meeting 947-B1 is backward-compatible and safe to use. Both specifications have largely been superseded by WSS-M2C962-A1, which aligns with API SP and ILSAC GF-6A. That standard sets even higher benchmarks for timing chain wear and LSPI protection than either of the 947-series specs.
Compatible Engine Oils
To help you navigate your options, we’ve listed the leading aftermarket engine oils that not only meet but often exceed Ford’s WSS-M2C947-A performance benchmarks.
Valvoline Advanced Full Synthetic 0W-20
Valvoline Advanced Full Synthetic
Valvoline Advanced Full Synthetic 0W-20 is an aftermarket-equivalent option for vehicles requiring WSS-M2C947-A, meeting the standard through its Ford WSS-M2C972-A1 recommendation.
Valvoline carries full API SQ and ILSAC GF-7A approval, the latest industry certifications, which means it exceeds the API SN Plus requirements the 947-B1 update introduced. It also holds GM dexos1 Gen3 licensing.
Quick Specs
- Viscosity: SAE 0W-20
- KV100: 8.4 cSt | KV40: 44 cSt
- HTHS: 2.7 cP
- Pour point: -39°C
- Viscosity Index: 171
- Zinc/Phosphorus: 900/780 ppm
Valvoline Advanced Full Synthetic 0W-20 is a practical choice for EcoBoost owners who want LSPI protection. The high viscosity index of 171 means the oil resists thinning under heat, keeping pressure consistent across operating temperatures.
- Also recommended for: Chrysler MS-13340
- Also approved: API SP, ILSAC GF-6A, API SN Plus, GM dexos1 Gen3
Castrol EDGE 0W-20 U.S.
Castrol EDGE Advanced Full Synthetic
Castrol EDGE 0W-20 is an aftermarket-equivalent for WSS-M2C947-A, meeting the standard through its explicit WSS-M2C947-B1 and WSS-M2C962-A1 approvals (both of which are backwards compatible with the original 947-A requirement).
Castrol EDGE 0W-20 was specifically tested against the LSPI and timing chain wear criteria the B1 revision introduced for EcoBoost engines.
Quick Specs
- Viscosity: SAE 0W-20
- KV100: 8.7 cSt | KV40: 49 cSt
- Pour point: -42°C
- CCS at -35°C: 5,700 cP
- Viscosity Index: 161
- Flash point: 220°C
The pour point of -42°C is among the stronger cold-start figures in this class. This means the oil reaches critical engine components faster during cold starts, which is where most wear occurs. It meets API SP, ILSAC GF-6A, ACEA C5, and is approved for Chrysler MS-6395.
- Also approved for: Chrysler MS-6395, GM dexos1 Gen 2 (D10301HD082)
Pennzoil Ultra Platinum 0W-20 Full Synthetic
Pennzoil Platinum Full Synthetic
Pennzoil Ultra Platinum 0W-20 is one of the few aftermarket-equivalent oils that explicitly lists both Ford WSS-M2C947-A and WSS-M2C947-B1 on its datasheet.
Pennzoil uses a natural gas-derived synthetic base through their PurePlus process to minimize impurities. In practice, that translates to a cleaner oil that resists sludge formation.
Quick Specs
- Viscosity: SAE 0W-20
- KV100: 8.8 cSt | KV40: 46.3 cSt
- Pour point: -48°C
- CCS at -35°C: 5,670 cP
- Viscosity Index: 172
- Flash point: 208°C
The -48°C pour point is the strongest cold-start figure in this group. If you’re in a cold climate and running an EcoBoost, that number matters when you turn the key in the ignition.
- Also meets: Ford WSS-M2C947-B1, Chrysler MS-6395
- Meets or exceeds: API SP, ILSAC GF-6A, ACEA A1/B1
Motul 8100 Eco-Lite 0W-20
Motul Synthetic ECO-LITE
Motul 8100 Eco-Lite 0W-20 is an aftermarket-equivalent for WSS-M2C947-A. Its datasheet explicitly lists compatibility with WSS-M2C947-A, WSS-M2C947-B1, and WSS-M2C962-A1.
Quick Specs
- Viscosity: SAE 0W-20
- KV100: 8.4 cSt | KV40: 45.2 cSt
- HTHS: 2.6 mPa.s
- Pour point: -42°C
- Viscosity Index: 162
- Flash point: 223°C
Motul 8100 Eco-Lite 0W-20 carries API SQ-RC and ILSAC GF-7A, the latest industry certifications as of this writing, which supersede the API SN Plus requirements the 947-B1 revision introduced.
One distinction worth noting is its HTHS viscosity of 2.6 mPa.s, sitting at the minimum threshold for 0W-20 oils. This is by design for a fuel economy-focused formulation. But if your EcoBoost runs hard or in high ambient temperatures, it’s a number to be aware of.
- Also meets: Ford WSS-M2C947-B1, WSS-M2C962-A1, Chrysler MS-6395, Fiat 9.55535-CR1
- Also approved: GM dexos1 GEN3, API SQ-RC, ILSAC GF-7A
Motorcraft SAE 0W-20 Full Synthetic
Motorcraft Full Synthetic
Motorcraft SAE 0W-20 Full Synthetic is Ford’s OEM oil for WSS-M2C947-A applications. It carries the WSS-M2C962-A1 specification, which is backwards compatible with both 947-A and 947-B1.
Quick Specs
- Viscosity: SAE 0W-20
- KV100: 8.5 cSt | KV40: 45 cSt
- Pour point: below -50°C
- CCS at -35°C: 5,550 cP
- Viscosity Index: 169
- Flash point: 226°C
The practical advantage here is warranty coverage. As the Ford-branded oil, it satisfies all Ford warranty requirements by definition, which matters if your EcoBoost is still under a powertrain warranty and you want zero ambiguity at the dealer.
- Also meets: API SP, ILSAC GF-6, API SN Plus
Specifications that Replaced WSS-M2C947-A
WSS-M2C947-A has gone through two successors, each driven by a specific engine protection problem that the previous spec didn’t fully address.
The first update was WSS-M2C947-B1, Ford’s response to Low Speed Pre-Ignition (LSPI). The B1 revision aligned with API SN Plus, which introduced formal LSPI testing requirements and stricter timing chain wear standards not present in the original spec.
The current standard is WSS-M2C962-A1, introduced in May 2020 alongside Ford’s broader 96x-A1 spec series. It reflects the move to API SP and ILSAC GF-6A, setting even higher benchmarks for LSPI protection and timing chain wear than B1. For 0W-20 applications, 962-A1 is what you’ll find on newer Ford vehicles, including the 2023 Maverick.
If your vehicle originally requires 947-A, an oil meeting 947-B1 or 962-A1 is backwards compatible and exceeds the original requirement on every meaningful performance criteria.
Closing Notes
The move from 947-A to 947-B1 to 962-A1 addressed a real failure mode that the previous standard wasn’t equipped to handle.
Meeting the spec is the baseline. For owners who tow regularly or run in stop-and-go traffic, two numbers are worth attention beyond the label.
Shear stability determines whether the oil holds its rated viscosity grade under sustained turbocharger stress. NOACK volatility measures evaporation at high temperature. Lower evaporation means fewer oil vapors entering the intake. This is important for valve cleanliness in direct-injection engines where carbon buildup is a known long-term problem.
For most owners, a 962-A1 approved oil at Ford’s recommended intervals is sufficient. If you’re pushing the engine harder, shorten your oil change interval.
