Time for the update to this thread. Beginning of the month, I was at the add mark finally on the dipstick. Approximately 3500 miles since oil change. I therefore added a quart of oil. Today, for no reason at all, I decided to check again (were not driving the miles we used to before this COVID thing) noticed it was down or at the half mark on the dipstick. Thought this was odd as it had only been about 500 miles since I had added a quart. Now, I didn't check the level right after I had added at the beginning of the month as I should have, but 500 miles to a half qt seemed pretty excessive. Tried an experiment at this point. I added another quart and waited about 30 minutes to see where that put it on the dipstick. It was actually just at the full mark now. So, in reality, the marks on our dipstick, at least the one that we have, it is a 2 qt difference between add and full. When I recalculated the oil consumption, ti comes out to just over 2000 miles/qt. That's after having the TSB completed, etc.

Will be calling our dealer on Monday and seeing where it goes from here.

 

That consumption seems high for 500 miles. My Ford dealer told me if my engine needed oil, that I was to come in and let them add it and document it in the work order.
Hope you kept the receipts and any other proof that you added the oil. Ford may not believe that you added the oil. I heard the 2018 5.0L consumed more than the 2019's.
I had my TSB done on January 30th, 2020. I went back two or three weeks ago and had my Ford dealer top up my oil which was, according to them, down about 1/2 a liter.
Mileage driven from January when the TSB was done was 6.100 km or 3,790 miles. In my case, it seems to have helped getting the TSB flash on the PCM done.
Is your truck a 2018? Good luck when you go speak to your dealership. From the consumption you mentioned, sounds like Ford should have a hard look at your engine.

 

There is no “Ford believing”. The TSB is specific. Don’t fart around. Take the truck in, let your dealer document the issue, and follow the required course. It’s likely changed from when I had my engine replaced, but nonetheless, Ford does have specific protocols you need to follow, and “telling” them you added oil isn’t one of them.

 

Didn't you get a 3.0L F-150 after having issues with your 5.0L or am I thinking of someone else?

 

Yes, I did.

 

Did you replace it with a superduty? I always followed your posts very carefully and am very curious to know of your experiences with the 3.0L.

Not meaning to derail from the main subject but the 3.0L is rarely talked about.

 

I have had a 3.0L for about a year. I love it. I figured IF I could get 25mpg at $0.25 a gallon more than gas, I’d pay for the upgrade from my 2018 XLT to this 2019 Lariat. I’m averaging about 26-27mpg daily, and have been paying $0.20 less for diesel since I bought it here in N. Illinois. This truck fits the bill for me perfectly. It’s more than I expected, and although it isn’t fast ax an EcoBoost, I’ll run mpg circles around one all day long. And frankly, at fuel costs today, I am saving money. The savings just aren’t going to buy me a new Porsche or GT, but it IS savings. The oil changes and maintenance don’t even touch the bank. Nothing like a 6.7L, and easy to do all. I expect 150k plus miles without issue to be realistic. Did I jinx myself?

We bought a 24 foot travel trailer this summer, and my only gripe is payload. With four adults in the cab and an empty bed, I’m at payload, and within 100# of the gross axle ratings when full of water. I travel empty, but man does it pull. It won’t win a race into the interstate, but I average 13.5mpg pulling the trailer loaded, where my 2017 6.7K would get 10. Dragging my 10k gross flatbed with 3 quads, 20mpg is the norm. I’m glad I bought it. I’ve even managed to accept the short bed.

Will I get another? Really, I’m not sure. For towin this trailer and future plans, no. For what I do now? Yes, without hesitation.

 

Checked the oil in mine yesterday, after having the TSB performed and dipstick replaced it is less than 8 oz low after 4000 miles, truck now has 34000 miles on the meter.

 

Keep in mind that the new dip stick doesn't show to add oil until it's 2 quarts low.

 

Started my 2nd test a month ago. The last time it used just less than a quart and that was over a year ago.. This time they re-programed one of the computers and did the dip stick change. I guess it needs to use 2 quarts to qualify this time. My catch can oil container usually has about 2 oz of oil in it at 3000 miles and I pour it back in.. My 2018 has 23000 miles.

 

Yea it was only down about 1/8" from full so I guessed 8 oz or less, didn't add any as it'll get a change in another 1000 miles.

 

I have a 5.0, it burns oil now. I have no faith in Ford's remedy, I think they botched the engine and this is a band-aid. It's sad, I bought the 8 cyl because I figured they had enough miles under it to not F it up, I was wrong. A big strike for Ford IMO, and I've had a ton of them which is why I bought this one. This is what happens when you screw around with something that doesn't need it. For the first time in well over a couple of decades I'll look at other manufacturers the next go-around.

 

I wanted the 5.0 because of the durability of the v8. I did not know until after I got the truck that it's a completely different engine in 2018, nor did I know about the oil consumption problem. I went out to check the oil before a camping trip and what do you know, I had to add 1/2 quart. After getting home from the trip I checked today and added another 1/2 quart. I have been doing a lot of towing lately so I'll see what happens when it's just daily routine driving. Makes me glad I leased this truck. I'm sure I will be getting an f250 or some other 3/4 ton truck when this one is up. I haven't bought a new ford since 2003, and when I do bam! They sock it to me. I guess I'll check it every 3 to 4 weeks and dump some Walmart supertech in it when it needs it. Truck only has 3700 miles on it and I've added a quart already.

 

Have you had TSB 19-2365 completed? If not, I suggest you do. Give the truck more time, needs about 10k to settle down.

Mine went to using a quart every 2500 miles to nearly none after the TSB and hitting 10k miles. TSB even states oil consumption during the first 10k is expected:

 

yeah i should do that. Did you have the tsb done before you had 10k miles, or should i wait?
