It is research I did from this Thread
I have always thought why does my truck 2020, only take 13 quarts. If I lean the truck and let it drip for an hour I get more out and am at top line full with 14 quarts. My son has a 16 so using Tasca Parts, ran the following trucks 2011, 2014, 2015, 2016, 2017, 2019, 2020, 2021, 2022, 2023, 2024.
Taking the variables out of lower pan size and dipstick tube length 11-24 Lower oil pan BC3Z-6695-C 11-15 Dipstick tube upper BC3Z-6754-C (Discontinued) 16-17 Dipstick tube upper BC3Z-6754-D 18-24 Dipstick tube upper H3CZ-6754-B 11-24 Dipstick tube Lower B3CZ-6754-A 11-16 Dipstick BC3Z-6750-C (HC3Q-6750-DA) (48.75" Length - Tube shoulder to tip) 17-22 Dipstick HC3Z-6750-C (HC3Q-6750-AA) (Re-Released) (49.5" Length - Tube shoulder to tip) (Thanks to @AppleFordParts for the confirmation 23 Dipstick PC3Z-6750-A (PC3Q-6750-AB) (Discontinued) (48" Length - Tube shoulder to tip) 23-24 Dipstick PC3Z-6750-A (PC3Q-6750-AC) (48.375" Length - Tube shoulder to tip)
The lower pan is the same for all years of 6.7 as far as depth Tube is different from Upper tube has three variations, lower is the same for all years The dipstick has FOUR different lengths. Here are three of them.
I will be ordering a replacement for mine, (since mine is discontinued!. And I can have the increase and still have it on the stick properly.
Update: Feb 25, 2025 I got the opportunity to go by my local dealer parts. I he confirmed my findings that there are no capacity differences in the 6.7 over the years. Ford has adjusted the oil dipstick length.
All years of 6.7 can have a capacity of 15 qts.
There is no difference in the windage tray or anything else. There is a newer upper oil pan for the MY24. It has a solenoid on it now.

I have a 22 6.7 with the 13 qt capacity.If I am understanding you right the lower dipstick tube is the same on all 6.7 engines and by getting the dipstick for the 23,24 model listed it will give you the same capacity as a 24 engine. (15 quarts) . I have always been cautioned about overfilling. There must be quite a bit of extra capacity built in to the 6.7 pan.

thank you for the information

Exactly correct. The tubes and pans are the same. The dipstick itself is longer (AA) vs shorter (AC)
So with things being about equal, the same oil pan size, the same upper "pan" size, the same lower oil dipstick tube, the same engine design minus various changes like pistons, turbos, fuel system changes, etc... wouldn't the engine oil capacity remain the same?
Riddle me this Batmen, wouldn't an older truck like mine for example, be able to take 15 quarts, like new 23s and up?
We all know that at least 3 quarts of old oil remains in the block when doing an oil and filter change.
So when the 6.7 H.O. came out and Ford said it had a 15 quart oll capacity, and if everything that holds oll (upper pan, lower pan, filter etc) is the same as the standard 6.7, does that mean Ford just used a different dipstick to show the correct level of oll with 15 quarts in the engine??

I would have to imagine... so instead of having at least 17 quarts of oil in the block with a 13 quart oil and filter change, it will have at least 19 quarts of oil in the block.
Going from a longer 49.5" dipstick to a shorter 48.375" dipstick, all else being equal, has to result in more oil in the pan. 1.125" is a lot of volume. I don't have a lower pan handy to calculate that out, but it has to be close to two quarts.
So, if we're adding more oil and using a shorter stick, then I'm assuming it's okay for a 6.7 Powerstroke to have 15 quarts in the oil pan. Any newer truck owners running a full 16 quarts of oil?
15qts gets a guy to 3 Motorcraft 5qt bottles. That’d be handy, and nice to not have to deal with partials.
Edit: If it was safe, no reason even to change out the dipstick. I wonder if they kept the ‘low’ at the original level?
Great point Dave... I've been using Rotella T4 and T5. But if more looking into this reveals that, maybe go back to Motorcraft 5 quart jugs. What grade you run?
🤯 This whole time I assumed they must have used a larger pan under the '23+ to gain additional capacity...now the question, why up the capacity on this newest gen of 6.7l and not the earlier engines.

Because it's what they've sold lately. They care about the older models only when required to through a recall. There's no money is revising older manuals. Marketing on the other hand loves to publish more impressive specifications for the current model year.

Motorcraft 10W30 diesel. Between my two 6.7’s I’ve put over 400k miles combined, changing when the truck tells me to

Are there any benifits to increasing the capacity by 2 quarts other than marketing?
