Why 5W-20 is Critical for the Godzilla V8
The 7.3L Godzilla is a pushrod OHV engine — Ford’s largest gas V8 since the 460 — with a cast-iron block, high 10.5:1 compression ratio, and port fuel injection. Despite its massive displacement, Ford specifies 5W-20 to maximize cold-start oil pressure delivery to the hydraulic roller lifters and main/rod bearings. At 13.1 quarts, this engine holds more oil than most six-cylinder trucks; that large sump extends oil life and stabilizes temperatures during heavy towing and hauling.
Using incorrect oil will:
- ❌ Delay oil flow to hydraulic roller lifters, causing lifter tick and premature wear
- ❌ Increase engine start friction when a thicker viscosity resists cold-weather flow
- ❌ Void Ford’s powertrain warranty if the oil does not carry the WSS-M2C946-B1 spec
Ford-Approved Oil Brands
-
✅ Motorcraft Full Synthetic 5W-20
-
✅ Mobil 1 Advanced Fuel Economy 5W-20
-
✅ Castrol EDGE Full Synthetic 5W-20
-
✅ Pennzoil Platinum Full Synthetic 5W-20
-
✅ Valvoline Advanced Full Synthetic 5W-20
Confirm the label displays API SP certification and Ford WSS-M2C946-B1 approval. Do not use conventional or synthetic-blend oil — the 7,500-mile interval requires full synthetic to maintain viscosity throughout the change interval, especially under sustained towing loads.
Severe Service Check
Use the 5000-mile interval if you:
- Tow at or near the maximum 21,200-lb rating regularly
- Haul heavy payloads on a daily basis
- Operate in extreme heat above 100°F for extended periods
- Idle the engine for long periods (job site use, auxiliary power)
Installation Details
Drain Plug Torque: 19 ft-lbs
Replace the drain plug crush washer at every oil change. The 7.3L uses a standard 18mm drain plug with a copper sealing washer.

Pro Tip: At 13.1 quarts, the F-350’s Godzilla V8 takes significantly more oil than most owners expect. Use a dedicated oil drain pan rated for at least 14 quarts. The spin-on filter is located on the front-driver side of the engine block — accessible from below without a lift on most configurations. Ford’s Intelligent Oil-Life Monitor will display a wrench icon and “OIL CHANGE REQUIRED” message when service is due.
FAQs
What oil does a 2022 Ford F-350 7.3L V8 take?
5W-20 full synthetic meeting API SP and Ford specification WSS-M2C946-B1.
How many quarts of oil does the F-350 7.3L need?
13.1 quarts with a new filter, 12.5 quarts without.
Can I use 5W-30 in my F-350 7.3L?
Ford specifies 5W-20 for this engine. Using 5W-30 may be acceptable as a one-time emergency fill, but continued use can reduce fuel economy and cold-start protection. Return to 5W-20 at the next change.
Is synthetic oil required for the Godzilla V8?
Yes. Full synthetic is required to achieve the 7,500-mile oil change interval and meet the WSS-M2C946-B1 Ford specification.
How often should I change the oil on a 2022 F-350 7.3L?
Every 7500 miles under normal driving. Ford’s Intelligent Oil-Life Monitor may recommend earlier changes under heavy towing or severe conditions.
Why does the 7.3L V8 need so much oil?
The large 13.1-quart sump is intentional. More oil volume means more thermal mass to absorb heat during sustained towing, longer drain intervals, and reduced oxidation from dilution of combustion byproducts.
