Here it is...the definitive answer to our issues! The facts:

The correct stick is PN MB3Z-6750-B

It is 7/8 of an inch shorter from the base of the handle to the MAX line than the current sticks in our Broncos.

Note the pics...showing side by side comparisons of overall length and max mark lengths. Also note my oil position as measured PER THE MANUAL on the "new" stick. If you want an accurate oil measurement using the procedures indicated in the manual, with 7 quarts, buy the MB3Z-6750-B. I ordered it from my dealer Friday, it came today...19.45.

Thanks Rob!
You are most welcome...this stupid dipstick thing has haunted me since my first oil change back in October...my hope now is that it is TRULY the correct stick (it is now listed as such in the parts database) rather than Ford teasing us with a "7 quart oil capacity" and then later figuring out that although it holds 6 that it needs an entirely different stick to get an accurate reading (which the new one does beautifully). Call me skeptical but it seems really odd that the "solution" to the initial stick reading a quart off is repurposing an existing stick intended for an entirely different engine perplexes me. Even so, it makes me happier that at least all appears well as soon as I measure my oil.

I would wager that a lot of folks, however, will buy the right stick, then check their oil immediately after adding it and not wait the at least 15 minutes, and then complain that their oil measures too low...wait for it...

So to everyone...if you buy the correct stick, please wait until AFTER 15 minutes has passed after shutting off your car/adding oil to check the level (as per the manual).

Just want to point out that the engineering header classifies it specifically as a 2.7L Nano RWD U725 so I don’t actually think anything was reused from a 3.5L but I am also not saying that’s absolute either.

It's been bothering me too. I can't believe Ford could make this kind of mistake to begin with let alone taking a year after production to correct it.

Whenever I change my oil I always make a final check after it's been sitting overnight and top off in the morning.

My limited researching on this part number comes up specific to the 21-22 Bronco. Not sure where the 3.5l link originated from. A lot of these part numbers seem seem similar and I confused them a couple times.

Interesting this part number was referenced back in January.

Way earlier in this thread I shared that when I went to a dealership in AZ, a month after I received my Bronco, I wanted to sleuth and even then (November) I was told that the correct number was the MB3Z number...but they didn't have one in stock. Not sure why, if Ford indicated that the correct stick was in fact the MB3Z one, why up until even now Broncos have the wrong stick?

Do you know, did they just get these in stock?

My dealer does not stock them but it was cool that they get one in just a few business days. I went with the dealer that was local because if you type the part number in online, loads of places list it but then you won't know when it is going to arrive so I went with talking to a live person. I'd rather spend the 20 bucks than wait until Ford gets around to offering to replace our old ones...if they even do offer. They have run silent on this one since the beginning, which is odd because the solution seemed to have been known since at least November.

The question is… did those of us that filled only to the max fill hole on the original stick cause any damage?

I’ve apparently been running ~0.825 qt short for 2k miles since I decided to heed the owners manual text that stated specifically to not run above the max fill hole, knowing full well this contradicted the 7qt specifications (either option required disobeying the other; I chose to go with the one that allowed me to use something measured and graduated to reason about the fill level, but apparently this was the wrong decision)…

Regardless of the potential of sustained damage, I now feel the need to go perform a full drain and 7qt fill thousands of miles early since there’s no f***ing way to just add and measure where I’m at with the factory dipstick I was provided.

I doubt any damage was done at running 6 quarts...as long as the oil pump is able to pump oil under full pressure/no cavitation continuously no issues. With one quart less your oil will reach the end of its useful life sooner, but depending on the oil that should be far beyond 2k miles.

So, is the correct number MB3Z or MB3E?
