. My God some of you really go off on tangents!!

Flip, thanks for the info. I’m still unclear what to do. I just got back from my dealership for my first service. The dip stick is at least 1 inch above max. What action if any do you think I should take.

If the invoice says they put 7 in, let 'er eat.

I kind of scanned all the post, so maybe it's already been said.

But if folks are only getting six quarts out when they drain, but they're putting seven quarts back in because the dipstick is wrong and that's what the manual says..

How many oil changes before you have so much extra oil in there that you ARE going to cause damage.

Obviously I hope Ford sorts this out and gives us some better information. My second hope is that when I finally get my Bronco, I have the odd luck that the dipstick actually registers correctly like a few others have.

Otherwise, maybe I'll see how many courts it takes to get to the max line. And if it is six, toss in a half a quart to split the difference.

1} I drove until the engine was hot. Parked and waited 20 minutes then removed the oil filter.
2} Let oil drain from filter housing for at least 20 minutes.
3} Removed drain plug and waited 2 hours until oil dripped 1 drop in about 20 seconds.
Measured: Engine gave out 6.25 quarts. I put in 6.75 quarts.

I'm either under filled by .25 quarts or over filled by .50 quarts.

EDIT: after waiting overnight dip stick showed oil half way up on the twist.
my dipstick is # FT4E6750BF D454A

So I changed my oil about 4K miles. Saw some questions about fill, but let it drain for 20+ minutes and refilled with 6 quarts of Mobil 1. Came just under the “full” hash mark and thought it was good. Today I checked and the oils level was just a bit lower, middle of the “safe” hash marks. I know that I was safe to add, based on the capacity and slight decrease in level, I added a quart of the same 5w30 Mobil 1. Now shows slightly over the full mark. I will be super diligent and drain top and bottom and measure. I will replace what comes out and verify level with a scroll mark on the dipstick. My oil change friends will scold me for not doing so the first time (I was taught this early in my wrenching career and just neglected to follow established best practices). To affirm what many others have said, the quart difference one way or the other isn’t going to burn up the motor or drop a valve. Which of the horrible service managers do you all refer to? IME, they are mostly looking to resolve the issue and get the dealer and tech paid for their work. Nothing more or less. Happy Thanksgiving 🦃!

And after waiting at least 15 minutes, where was it on your dipstick?

da-jokker: the oil showed right at half way on the twist of the dip stick.

that is very close to where it showed on factory fill.

Exact same for me. 1,100 miles in...I asked the dealer tech to check dip stick level after adding 7 quarts; he was happy with it. Waited overnight - same stick# and reading as you. If its wrong, at least we have a lot of company

What I don’t understand is…. (And I’ve built several engines with modified baffling and wind age trays) with the same dip stick inserted into the block… you fill to the same oil level. For example if you install a large capacity pan you would add more oil, but the actual level on the dip stick would be the same.

If ford built a larger pan for the 2.7 Bronco to handle 7 qts…. The max fill mark should be at the same level…with the same dip stick….

This concept of adding a 7th quart and rising the oil 1” past the max fill mark (into the twisted section) makes Zero sense….

If the crankshaft is splashing in oil it’s not a good thing… In addition, making excess blow by at full boost with the turbos… along with an overfilled sump, would be a recipe for disaster….

This whole oil level thing is NOT trivial. To guess what the max fill oil level should be (without sound reasoning), is crazy…..Ford needs to address this issue immediately….

Ford if your listening, please help us out here!!!

1000% agree...finally a fellow engine builder who understands both the importance of not overfilling but also the concept of the same oil level height regardless of pan depth...and as a bonus the implications of too much oil in a boosted engine...
