2025 hybrid awd came out to oil on garage floor

[WJOHNM]

Leaking oil this morning from bottom of the skidplate. Couple days ago had oil,ptu, rdu fluids changed.

Looks & smells like the motor oil, but the dipstick shows full covering the top dimple cold.

--Ruled out PTU fluid leak since I have a bottle of 75W85, definitely thinner & doesnt have the PTU "onion" smell. Brake fluid thicker, clear & full.

So last oil source is hybrid drive, but I don't know what hybrid drive Mercon ULV looks & smells like & how to check it for leaks, could this oil be Mercon ULV?

I also 1 week ago had the car spray undercoated with Krown rust proof oil, doesn't look like the thicker Krown. Now I wish I hadn't, gonna suck looking for leaks.

1) Came out today to what looks like motor oil spilling out, yesterday had a 180mile drive.
oil, rdu, ptu fluids changed 4 days ago & haven't notice any leaks before.

Checked dipstick and oil is filled all the way. Color/smell on the floor matches oil on dipstick.

2) oil leakage is all at the oilpan change port, I haven't been under yet with skidplate off.

PTU is near same location as oilpan, but I have a bottle of Motocraft 75W85 & it is definitely not PTU fluid which is thicker with a distinct "onion" smell.

3) felt around the oil filter, oil filter is not oily even though in pic you can see some drips below it, may have migrated forward on the skidplate.

4) process of elimination: not brake fluid.

5) I will get dirty pulling off the skidplate & check for loose oilpan plug,

Question: if engine had been overfilled, would it spill out at some vent location so I dont need to worry?

Maybe the technician accidentally spilled oil on the skidplate when changed a couple days ago, and spilled oil only ran forward to spill when backing up my driveway.

That seems the most logical but I don't know what hybrid transmission Mercon ULV looks like, kinda scared if its a hybrid tranny leak that I wont be able to see it.

You say someone did a service, so why are you wasting time with all this anlisys, bring it back to shop who worked on it.

Krown will drip for a month and it looks like motor oil. I wasn't thrilled with that crap all over my driveway.

No problem, Changed everything just because I wanted to see the fluid from break in.
Debating doing Mercon ULV just to see it, or pull a sample out.

My trans. fluid was like new at 30k miles. I would go at least 50k myself.

Cheers.

Everyone you are talking to is WRONG. There are MANY threads on PTU/RDU oil changes, BOTH have a capacity of 16oz; one pint, half quart.

I was just talking about what the oil-change place said they charged me for, 2 bottles at a jacked up price from the Ford dealership.

Now Im confused: pints & quarts.

I use quarts because oil & fluids are sold in 1-quart bottles - so if I need 1.5 quarts I still need to buy 2 quart bottles to do the change.
I've never used pints to refer to anything but a big mug of beer. A pint is somewhere around 500ml & a quart is slightly smaller than a liter -- but unless motor oil is sold in liter bottles then giving ml is a more accurate but significantly less useful measurement.

Kinda like ignorant Europeans who keep spewing about "metric is the best" completely oblivious to the fact that Americans use metric just fine where its necessary, but for home cooking where approximate ratios are appropriate, measurement in teaspoons, tablespoons & cups are quicker & more intuitive, vs recipes in ml & mg requiring precise scales and measuring cups.

 

[JohnCondren1933]

That doesn’t help me here in Canada with damn metric! I Jest of course, had mine all done and all level and good. But don’t want to get into converting between the 2, I’m a boomer, and we know nothing!!!

Canadian-American here
Use both metric & imperial measurements where it suits.

Where referring to quarts make sense is for automotive fluid changes because they are (usually) sold in 1 or 5 quart bottles,
when you are asking "how much fluid"? you really want to know how many bottles of fluid to buy.

If you were told you need "3400ml" of oil you would need to do 3400/940 or however many ml are in a quart bottle, then add an extra bottle if the result has a modulus (remainder) - more "accurate" but less useful because more potential points of failure for getting the right # of bottles.

Same reason inches are used in residential wood-framing construction: 1 cm is too big a tolerance & 1 mm is way too small a real world tolerance - inches & 1/4 inch tolerance or 1/8 inch for critical areas is pretty common.

Legacy imperial/standard dimensions & parameters became problematic with automotive engineering, which is why it was arbitrarily declared that 1 inch = 2.54cm

Yes everyone is saying this & its what I did today -- but the service shop was 200 miles from my home I drove back home from a field service trip, & only noticed after I got home.
I was just worried here about risk/reward driving 200 miles back to the service shop to fix it when I returned, if it could've been anything else but the motor oil leaking.

EDIT: Problem was a leaking oilpan gasket after oil change, seems it wasnt seated properly, young new technician.
But only the 2nd oil-change ever, finding this strange, I've never replaced oil drainplug gaskets during oil change, I guess I need to buy one of those $40 valved oil drain plugs permanently mounted.

is replacing gaskets every oil change a thing now? I've also always only had steel oilpans, I guess oilpans are all now aluminum, horrible place to save weight!!

One more reason everyone needs a skidplate!! these stupid aluminum oilpans, hit a pothole one time you arent just blowing a tire, any contact youre cracking an oilpan destroying your engine if you dont shut down immediately.

It's not a 'thing' now- it's been around for god knows how long, just depends on the vehicle

Absolutely correct on quantity. I did both the PTU & RDU on mine same day. Each used less than a quart, 16oz or thereabouts.

A quart is larger than a litre.

 

[Darryl]

A quart is larger than a litre.

No it isn't. A quart is 0.946 liters look at any quart bottle of ANYTHING. a quart is 36 ounces whereas a liter is approximately 39 ounces.

 

[MikeS1942]

I stand corrected. A litre is 33.8 ounces, and quart is 32 ounces.

 

[Darryl]

I stand corrected. A litre is 33.8 ounces, and quart is 32 ounces.

I stand corrected as well. . I do know that A quart is 0.946 liters. I remember that one

I can't remember any of those conversions. I cheat. There is this gal, "Siri", who, apparently resides in my phone. I just ask her and BAM! Instant answer! Sure could have used this gal's help whilst taking those tests in high school and college! Ha.

To be honest, the main reason I remember the quart to liter conversion it's because it's literally marked on every can of oil . And I've been working on cars since I was about 12. An inch=2.46cm. I remember that because someone made a silly song in the late 1970s making the point that things just wouldn't be the same when we switched to the metric system. They used the kids song "Inch Worm" and changed the words to 2.46 centimeter worm. Back then my young mind was sharp enough to remember stuff without trying. I think to convert C to F temps it's 9/5 (or 1.8) C +32. = F. That's about it. Oh! And my parents tag number for the 1974 Ford LTD. It was 13w-16719. Again the 10-11 year old could remember stuff without trying. If I could delete some of that information that I would never, ever use again. Maybe I could remember new information. But my RAM and ROM memory is full.
