Ford Diesel Oil Capacity Chart: 1994-2026, 6.0, 6.4, 6.7 & 7.3 Power Stroke

Ford diesel oil capacity depends on which Power Stroke engine sits under the hood and, for the 6.7L, which model year and truck class you’re servicing. This chart covers the 6.0L, 6.4L, 6.7L, and both generations of the 7.3L badge so you can pour the exact amount instead of guessing.

Getting it wrong in either direction causes real problems: underfilling starves the turbo bearings, and overfilling causes foaming that cuts lubrication just as badly.

Use the quick-reference table below to find your engine and year, then jump to the detailed section for oil type and spec.

Ford Diesel Oil Capacity Chart: All Power Stroke Engines by Year

All figures include the oil filter. Always confirm against your VIN-specific owner’s manual before your first fill on a truck you’re unfamiliar with.

6.7L Power Stroke Oil Capacity by Year (2011–2026)

The 6.7L is the engine most owners are searching for, and its capacity has changed twice since launch, first by truck class and then by model year.

2011–2022 F-250 to F-600 pickups and chassis cabs: 13 quarts (12.3 liters) with the filter. This covers the entire Scorpion-block generation before the 2023 redesign.

2023 and newer F-250 to F-600: 15 quarts (14.2 liters) with the filter. Ford grew the oil pan and recalibrated the dipstick for this generation, so pouring the older 13-quart figure into a 2023+ truck leaves it noticeably low.

F-650/F-750 medium duty: These chassis run their own numbers regardless of pickup-line changes. From 2015 to 2022 they take 15 quarts; 2023 and newer models take 17 quarts.

Every 6.7L in this range meets Ford’s WSS-M2C171-F1 specification. 10W-30 is the standard year-round oil; 5W-40 is the approved alternative for severe cold climates or when running B20 biodiesel blends. If you’re pulling your capacity data from an older bookmark or forum thread, it’s worth cross-checking it against our 2020 6.7 Powerstroke oil capacity breakdown, since that generation sits right at the 13-quart figure before the 2023 change.

7.3L Power Stroke Oil Capacity (1994.5–2003)

The original 7.3L Power Stroke takes roughly 15 quarts with the filter, running 15W-40 conventional or synthetic-blend diesel oil.

One warning worth repeating: don’t confuse this engine with the modern “7.3L Godzilla,” a gas V8 introduced in 2020 for Super Duty and medium-duty trucks. Same displacement number, completely different engine, completely different oil requirement (the Godzilla runs 5W-30 meeting WSS-M2C961-A1, per Ford’s current owner’s manual, and holds 8.0 quarts).

If you’re ordering oil online and searching “7.3 oil capacity,” double-check which engine your build sheet actually lists before you buy. For the classic HEUI diesel specifically, our 7.3 Powerstroke oil type and capacity guide goes deeper into the hydraulic-injection role oil plays in this engine.

6.0L Power Stroke Oil Capacity (2003–2007)

The 6.0L Power Stroke takes approximately 15 quarts with the filter, running 15W-40. The 6.0L’s oversized sump exists partly because the EGR cooler dumps significant heat into the oil system, so the extra volume does double duty as a heat sink in addition to lubrication. This is also the generation where staying on top of oil changes matters most for engine longevity. For a deeper look at real-world capacity behavior on this engine, see how much oil a 6.0 Powerstroke takes.

6.4L Power Stroke Oil Capacity (2008–2010)

The short-lived twin-turbo 6.4L Power Stroke holds 15 quarts with the filter, and Ford calls for 5W-40 meeting WSS-M2C171-D. The heavier viscosity and matching 15-quart capacity to the 6.0L reflect the heat load from the twin-turbo setup and frequent DPF regeneration cycles this engine is known for.

Which Oil Type Each Power Stroke Engine Needs

Capacity gets the truck running. The wrong oil type is what shortens the engine’s life. Match the Ford spec, not just the viscosity number on the shelf.

The WSS-M spec matters more than the API category alone, since Ford’s material spec accounts for the additive package these engines specifically need to protect turbo bearings and injection components. For the full picture across gas and diesel Ford engines, our Ford Engine Oil Recommendation Chart covers every current powertrain by WSS code.

Getting Your Power Stroke Oil Fill Right the First Time

Ford diesel oil capacity isn’t one number. It depends on which Power Stroke engine you’re running and, on the 6.7L, which model year and truck class it belongs to. Match your VIN or door-jamb sticker to the correct row above before you crack open a single quart, and don’t rely on a rounded “15 quarts for all diesels” rule of thumb. The dipstick reading only means something once you know the correct target for your specific truck.

FAQ

How many quarts of oil does a 6.7 Powerstroke take?

13 quarts with the filter for 2011–2022 F-250 through F-600 pickups, and 15 quarts for 2023 and newer models in the same class. Medium-duty F-650/F-750 trucks run 15–17 quarts depending on year.

Does 6.7 Powerstroke oil capacity change by year?

Yes. Ford increased pickup-line capacity from 13 to 15 quarts starting with the 2023 model year, and medium-duty trucks jumped from 15 to 17 quarts the same year.

What oil does Ford recommend for the 7.3 Powerstroke?

The classic HEUI diesel (1994.5–2003) runs 15W-40. Don’t confuse it with the modern “7.3L Godzilla” gas V8, which requires 5W-30 meeting a completely different Ford spec.

How much oil does a 6.0 Powerstroke hold?

Approximately 15 quarts with the filter, though this should be confirmed against your specific truck’s owner’s manual before your first change.

Can I use 5W-40 in a 6.4 Powerstroke year-round?

Yes. 5W-40 meeting WSS-M2C171-D is Ford’s standard recommendation for the 6.4L in all climates, not just cold-weather use.
